Definitions
- the present invention relates to a hairdresser's aid, and in particular concerns a masking aid that is adapted to engage and mask selected strands of hair from other strands of hair while the selected strands are treated, for example by a bleaching or colouring process.
- European Patent no. 0,122,145 discloses a hairdresser's masking sheet comprising a substrate of flexible material having an adhesive strip carried by the substrate for effecting attachment of the sheet to selected strands of a head of hair prior to treatment and for rapid removal of the strands from the substrate after treatment.
- the masking sheet comprises two rectangular panels, of substantially the same dimensions, which are welded together along a common edge to form a transversely extending hinge about which the panels are pivotable relative to one another. The hinged joint enables the panels to be hinged apart to receive the selected strands of hair between the panels and brought into proximity with each other to envelop the selected strands so that the strands may undergo a treatment process within the envelope so formed.
- the masking sheet comprises a first panel of opaque flexible sheet material, for example polyester, and a second panel of substantially transparent flexible sheet material welded to the first along a common edge.
- the transparent panel allows the hairdresser to monitor the progress of the colouring/bleaching process.
- the adhesive securing means becomes ineffective when brought into contact with many of the substances used to treat the selected hair. Consequently, the device tends to be labile, often slipping from the selected hair, thus requiring repositioning or replacement.
- the strips of adhesive material provide a barrier to treatment substances. Therefore, it is difficult to treat all of the selected hair within the envelope, particularly the roots of the selected strands that remain outside the envelope on the other side of the adhesive strip in use. Additionally, a problem experienced by hairdressers includes excessive application of treatment substances.
- the application of too much treatment substance to the hair or to the interior of the envelope can lead to over processing of the selected strands, wastage of treatment substances and leakage of excess treatment solution from the envelope.
- the latter can be particularly problematic if excess treatment solution drips onto the clothing of the person undergoing the treatment process and causes bleaching or discolouration thereof.
- too much treatment solution is applied and over processing occurs, the selected strands tend to tangle with neighboring strands when the treatment solution is washed out and the hair is dried. This can lead to some of the selected strands breaking when subsequently combed.
- a hairdresser's masking aid for masking selected strands of a head of hair from other strands of hair while the selected strands are treated, the masking aid comprising at least two panels of flexible sheet material which are capable of being hinged apart to receive the selected strands of hair between the panels and subsequently brought into proximity with each other to envelop the selected strands in use, characterized in that the masking aid further comprises a bag like reservoir pouch for containing treatment process substances or
- the pouch is preferably provided in a region of the masking aid remote from the end of the masking aid in proximity to the scalp in use.
- the pouch is provided in a region of the masking aid furthest from the end -f the masking aid in proximity to the scalp.
- the panels are hinged together along a respective edge of the masking aid and the pouch is provided adjacent to the hinge between the panels.
- Adjacent panels may be partially sealed together to provide a partially sealed pouch between them or each pair of adjacent panels.
- one side of the pouch is open for receiving excess treatment solution applied to the selected strands in use.
- a window of substantially transparent material is provided in the pouch.
- the window enables the hairdresser to observe the level of excess produce in the reservoir in use, even if working in a different area of the hairdresser's salon or on a different head of hair. This can alert the hairdresser to prevent leakage from the reservoir if the reservoir is close to overfilling.
- the reservoir may provide a receptacle for treatment substance, preferably liquid treatment substance.
- the reservoir may act to receive excess treatment substance, or to house treatment substance, or precursors thereto, prior to treatment taking place.
- the reservoir may be provided with an absorbent substance, a porous substance or a treatment neutraliser, which may be used to mop up, store or neutralise treatment substance.
- the reservoir is preferably formed in an area of the sheet remote from the scalp, i.e. in spaced relation to the scalp, preferably a portion of the sheet disposed furthest away from the scalp when in use.
- the reservoir is preferably formed adjacent the pivotable portion (hinge), which joins the portions of the sheet.
- the reservoir may comprise a trough, blister or bubble type pouch formed in or by one or more parts (panels) of the sheet.
- the reservoir comprises a trough, blister or bubble formed adjacent the hinge between the two panels.
- the reservoir is formed from flexible, optionally resilient material. Resilient material allows the reservoir to retain its volume after, for example, being squeezed.
- the two panels are partially sealed together to form a flap or' tab with the reservoir formed therein, and means are provided to enable liquid to flow into the reservoir from the unitable envelope or vise versa.
- One or more channels may be formed in the sheet material, or in a selected portion thereof, which directs liquid into or out of the reservoir. Similarly, a channel or channels may be formed in the sheet, which allows distribution of liquid throughout an area of the sheet.
- the reservoir may be sealed prior to use.
- the reservoir may contain a treatment substance or precursor thereto.
- a frangible seal may be provided which is broken to allow treatment substance to enter the, envelope and treat the hair.
- the reservoir may be used to replenish the treatment substance in the envelope. For example, as treatment substance drains into the reservoir and collects, a squeeze of the reservoir allows treatment substance to be reapplied to the selected hair within the envelope as it is pushed out of the reservoir into -the envelope.
- the reservoir may be used to house treatment substance precursors.
- the reservoir may contain a colorant precursor or a bleach precursor.
- the hairdresser applies a first precursor to the selected hair and unites the panels to envelop the hair.
- the reservoir may then be opened, for example by breaking a frangible seal, and a second precursor is expelled therefrom, into contact with the precursor on the hair.
- a reaction between the precursors then takes place resulting in treatment of the selected hair. This is particularly advantageous as it provides a relatively clean treatment process. For example, handling of messy or hazardous treatment substances prior to application to the hair is avoided.
- the reservoir preferably has a volume of 0.1 -5ml , more preferably 0.25-3ml , most preferably about 2ml .
- the sheet is preferably constructed in whole or part from a flexible polymeric material, for example a polyolefin.
- a portion of the sheet or all of the sheet may be constructed from a metal foil material.
- at least some area of the sheet is opaque, preferably a light coloured material, preferably a substantially white material.
- an opaque sheet comprises a window of transparent material through which the selected strands of hair may be viewed.
- the masking aid comprises a metal foil sheet material laminated with a thin film of transparent polyester or like material.
- the sheet material is preferably rectangular, most preferably elongate rectangular material. In some embodiments, for example, where a reservoir is present, extensions to the sheet material of a n ⁇ n-rectangular shape may be provided.
- the two panels of the sheet are preferably of substantially equal area. It is particularly preferred that when the two panels are united, one panel may be substantially superimposed on the other.
- the panels may be formed from a single sheet of material provided with a pivotable portion enabling the two panels to unite or approximate to form an envelope.
- the pivotable portion may be a hinge, for example, a hinge created by plastically deforming the sheet material to form the hinge.
- the masking sheet may be formed from two separate panels, which are attached to one another, for example welded or heat sealed together, to form the pivotable portion.
- the pivotable portion is a transversly extending hinge.
- a hairdresser's masking aid for masking selected strands of a head of hair from other strands of hair while the selected strands are treated
- the masking aid comprising at least two panels of flexible sheet material which are capable of being hinged apart to receive the selected strands of hair between the panels and subsequently brought into proximity with each other to envelop the selected strands in use, characterized in that the masking aid further comprises securing means adjacent an edge of the masking aid having liquid conducting channels formed adjacent thereto, said channels adapted to facilitate liquid flow past the securing means towards the edge of the sheet.
- the liquid conducting channels enable a greater percentage of selected hair to be treated, in particular, hair located close to the edge of the masking aid, for example portions of the hair adjacent the scalp.
- the liquid conducting channels facilitate liquid flow towards the roots of the strands by capillary action along with the enclosed strands of hair.
- the securing means may permit accurate location of the masking substrate relative to selected strands of hair so that the substrate abuts the scalp of a head of hair. This is particularly advantageous if bleaching or coloration of selected strands is required, thereby ensuring that the whole of the strands outwardly from the scalp are treated.
- the securing means may also permit accurate location of the substrate in a longitudinal direction of selected strands in spaced relation to the scalp, so that only selected, for example, lower portions of the selected strands between the scalp and the substrate may be treated.
- the securing means may be mechanical engaging means.
- the securing means comprise an adhesive, substance, preferably a pressure sensitive adhesive.
- adhesive may be adapted to adhere to hair and/or adjacent sheet material.
- a continuous or discontinuous adhesive layer may be applied to a portion of one or more of the panels.
- the adhesive may be in the form of a strip of adhesive or discrete islands of adhesive.
- the adhesive may be recessed in the surface of the sheet, or embossed thereon.
- securing means are located on one or both of the panels, which unite to form the envelope.
- securing means may be provided on the outer face of the sheet, i.e. the outer surface of the envelope in use.
- the securing means may be used to secure the sheet to hair strands external of the envelope, and/or to adjacent sheet material.
- the securing means are discontinuous.
- the securing means are discontinuous.
- the panels may be adapted to provide a space between the panels, which facilitates movement, by capillary action, of treatment solution.
- Such a space may be provided by spacing means, for example, protrusions on the surface of the panel, or for example, the securing means, such as an adhesive strip, may provide the spacing means.
- the surface of the panels in the channel regions may be treated or coated to facilitate capillary action.
- a flap or strap of material may be provided which folds across selected strands of hair and is attached to a portion of one of the panels, thereby trapping hair between itself and a portion of the panel.
- strands of hair maybe placed on the panel and the flap or strap folded across them to secure the sheet to the hair.
- the treatment may then be applied and the envelope closed.
- the flap or strap may itself comprise securing means, such as adhesive, for securing the flap or strap to the hair and/or a re-ipective panel.
- a hairdresser's masking aid for masking selected strands of a head of hair from other strands of hair while the selected strands are treated
- the masking aid comprising at least two panels of flexible sheet material which are capable of being hinged apart to receive the selected strands of hair between the panels and subsequently brought into proximity with each other to envelop the selected strands in use, characterized in that a first panel of the masking aid comprises an enclosed or partially enclosed securing means, the first panel having - apertures formed therein permitting the securing means to contact strands of hair, thereby securing the sheet to the hair.
- a flap is provided, preferably extending from a portion of a panel adjacent the scalp in use.
- the flap is preferably pivotly attached to a panel of the masking and sheet.
- the flap may be folded backinto engagement with a corresponding portion of the panel and/or into engagement with a material disposed between the panel and the flap.
- a portion of the panels may comprise a two-ply laminate structure, between which a securing means may be located. These arrangements preferably provide an enclosure or partial enclosure within which a securing means may be secured.
- the flap and/or the portion of panel adjacent the flap is provided with apertures, through which the securing means may engage selected strands of hair.
- the apertures extend through the pivotable portion, through which the flap is attached, to the panel.
- a comb-like structure may be provided, the panel and the flap bearing the teeth of the comb and the apertures providing the gaps between the teeth.
- a securing means may be sandwiched between the flap and the panel and may be visible in the gaps between the teeth of the comb-like arrangement.
- the enclosed securing means may be formed by folding a margin of the sheet back on itself to form a second envelope (with respect to the first envelope, hereinafter referred to, formed by approximation of the two panels of the masking) and sandwiching the securing means therebetween.
- the securing means may be adapted to contact hair strands both inside and outside the first envelope in use, but as the securing means are preferably slightly recessed in the apertures, do not engage adjacent sheets thus facilitating stacking or packaging of sheets without securing one to another.
- the securing means may be contacted by selected hair strands from within the envelope, through the apertures, and may be contacted by hair or adjacent sheets from outside the envelope. This provides a plurality of secure contacts, increasing the stability of the device.
- a hairdresser's masking sheet for masking selected strands of hair from other strands of hair while selected strands are treated, the sheet comprising two portions which are pivotable relative to one another such that one portion may be brought into proximity with the other portion so as to envelop the selected strands, characterised in that a portion of the sheet is provided with teeth and adapted to receive strands of hair in the spaces between teeth.
- the remaining length of hair is fully keratinised and is hard and horn-like in texture.
- the greater hardness, of the keratinised hair makes it much harder for the chemicals to penetrate the hair and this increases the amount of time required for the chemicals to be absorbed, which increases the process time. This is not necessarily a problem when highlighting selected strands by bleaching since the desired effect is to remove all pigment from root to tip and similarly where a whole head of hair is to be coloured darker than the hair' s natural colour.
- the difference in processing times is significant when a whole head of hair is to be coloured lighter than the hair's natural colour and currently it is necessary for the hair colourist to first apply the treatment substance to the middle lengths and ends of the hair and wait for a predetermined amount of time, for example 20 minutes, before the same substance is applied to the roots in order to achieve even colouring.
- a predetermined amount of time for example 20 minutes
- the hair colourist it is therefore, necessary for the hair colourist to periodically check that the roots have been processed sufficiently so that they are the same colour as the remaining keratinised part of the hair. As previously mentioned this involves the colourist periodically opening the envelope formed by the metal foil to observe the extent of the colouring process..
- a hairdresser's masking aid for masking selected strands of a head of hair from other strands of hair while the selected sfrands are treated
- the masking aid comprising at least two panels of flexible sheet material which may be hinged apart to receive the selected strands of hair between the panels and brought into proximity with each other to envelop the selected strands in use, characterised in that an edge portion of a substantially opaque front panel has at least one window for observing the root portions of the selected strands being treated within the envelope adjacent to the scalp.
- the front panel is also provided with a second window spaced from the edge portion for observing non-root portions of the selected strands within the envelope.
- the two-window arrangement (top edge window and second window), in this embodiment of the invention has the advantage that the hair colourist can easily monitor the different stages of activation of the treatment substance on the non- keratinised roots and the keratinised middle and end parts of the hair.
- the windows enable the hair colourist to monitor this process from a distance, for example, while working elsewhere in the colourist' s salon, for instance on another person's hair, without having to stop, go over to the person who's hair is being treated and open the foil or other opaque masking sheet to see how the reaction process is progressing, as is currently the case.
- the curled edge can also make the masking sheet more difficult to handle, particularly when the sheet is held in one hand while the hairdresser applies treatment solution to the selected strands with their other hand. It will be readily appreciated therefore that the hairdresser must take considerable care when using masking sheets of the aforementioned type to avoid treatment solution falling on the edge portion of the front panel during the application of the solution to the selected strands of hair.
- a hairdresser's masking aid for masking selected strands of a head of hair from other strands of hair while the selected strands are treated
- the masking aid comprising at least two panels of flexible sheet material which may be hinged apart to receive the selected strands of hair between the panels and brought into proximity with each other to envelop the selected strands in use, one of the panels having an adhesive contact surface or surfaces for removably attaching the masking aid to selected hair, characterised in that an edge portion of at least one other panel has a stiffness greater than the remaining part of that panel.
- the stiffness of the edge portion is sufficient to substantially prevent distortion of the edge portion, in particular curling, due to stretching when the edge portion is separated from the adhesive in readiness for use. In this way it is possible to prevent, or substantially reduce, leakage of the treatment solution from the upper edge portion of the masking aid/sheet in use.
- the edge portion comprises a plurality of layers -of the said flexible material.
- the stiffer edge portion comprises a portion of the flexible material folded over on itself to provide at least one additional layer.
- only one additional layer is provided, that is to say, the edge portion has twice the thickness and therefore twice the stiffness as the remaining part of the panel. The present inventor has found that this doubling of the thickness is sufficient to prevent distortion of the edge portion of the panel when the edge is separated from the adhesive on or associated with the adjacent panel.
- the panels are joined together along a common edge of the respective panels.
- the panels may be joined by welding, by the application of heat and/or pressure, by ultrasonic welding, or by adhesive along a common edge thereof.
- the panels maybe adjacent portions of the same sheet folded over each other.
- the stiffer edge portion is located along an edge of the panel opposite the hinged edge of the panels that is to say opposite the common edge of the masking aid/sheet where the panels are j oined together.
- the adhesive is provided along an edge of a first of the panels opposite the hinged edge and the stiffer edge portion of a second adjacent panel overlies the adhesive on the first panel when the panels are brought together.
- the adhesive may be provided as a single strip or in discrete pockets spaced apart along the edge of the first panel opposite the hinged edge thereof. When the adhesive is provided in discrete pockets the gaps between the adhesive pockets advantageously allow treatment solution to pass over the adhesive towards the roots of the hair being treated to ensure the selected strands of hair are treated effectively from root to tip.
- the masking aid of the aforementioned aspect of the present invention comprises a pair of hinged panels, that is to say the masking aid can be opened to form of a single substantially planar sheet.
- the masking aid comprises a plurality of hinged panels, including at least one further panel overlying the said second panel. This arrangement advantageously enables different strands of hair to be selected and positioned between different sheets so that different treatment solutions can be applied to different selected strands of hair substantially without cross-contamination of the treatment solutions.
- a first strand of hair may be selected by the hairdresser and placed between a first and a second of the panels for treatment with a first dye and a second strand, adjacent to the first strand, may be placed between the second and a third panel for treatment with a different colour dye.
- the panels are substantially the same shape and size so that they overlie one another when they are brought together.
- the panels are substantially rectangular .in shape.
- Another drawback associated with known masking sheets of the aforementioned type is that the sheets only permit one chemical treatment to be applied to the selected strands of hair engaged by the sheet.
- the masking sheets do not readily enable hairdressers to apply different dyes to adjacent strands of hair, for example the application of one colour to one strand and another colour to an adjacent strand, without using multiple sheets in close proximity to each other.
- a hairdresser's masking aid for masking selected sfrands of a head of hair from other strands of hair while the selected strands are treated
- the masking aid comprising a first panel and at least two fiirther panels of flexible sheet material that are hinged to the first panel in an overlying relationship with the first panel so that the panels may be hinged apart to receive selected strands of hair between the panels and brought into proximity with each other to envelop the selected strands in use, the said first panel having an adhesive contact surface or surfaces for removably attaching the panel to selected hair.
- the masking aid according to this aspect of the invention has at least two panels, which over lie another panel allowing different treatment solutions for different treatment processes to be applied to adjacent strands of hair.
- This arrangement advantageously enables different strands of hair to be selected and positioned between different panels so that different treatments solutions can be applied to the different selected sfrands of hair substantially without cross-contamination of the treatment solutions
- two further panels overlie the first panel so that a first strand. of hair may be selected by the hairdresser and placed between a first and a second of the panels for treatment with a first dye and a second strand, adjacent to the first strand, may be placed between the second and a third panel for freatment with a different colour dye.
- the present invention also contemplates embodiments where more than two additional panels are provided which overlie each other so that more than two different freatment solutions can be applied to different strands of hair in close proximity with one another.
- the panels are substantially the same shape and size so that the panels form a stack of panels joined together along a common edge.
- two or more additional panels may be are arranged side by side overlying one or more larger size panels.
- the first panel may have an adhesive contact surface or surfaces for removably attaching the panel to the selected hair to be treated, and an edge portion of at least one of the further panels has a stiffness greater than the remaining part of that panel.
- a first of the panels is substantially opaque and the additional panels are substantially transparent or have at least one substantially transparent window therein so that progress of the freatment process can be monitored by the hairdresser in use.

- Figure 44 is a perspective view similar to Figure 3 of a hairdresser's masking aid constructed in accordance with another embodiment of the present invention.
- an elongate sheet subsfrate 1 which constitutes a hairdresser' s masking sheet comprising two rectangular panels 2 and 3 of substantially the same size and shape.
- Panel 2 comprises a substantially opaque, preferably white, polyolefin or polyester flexible sheet material and
- panel 3 comprises a substantially transparent polyolefin or polyester flexible sheet material.
- the edges 4,4' of the respective panels that are in closest proximity to each other in the central part of the sheet are provided with respective semi-circular portions 6,6' which depend from the respective edges 4,4' and connect the panels at a common apex point of the semi-circular portions.
- the semi-circular portions are preferably pivotable with respect to each other about the apex 7, that is to say they may be folded over each other about a common fold line as indicated by the dashed line 7 in the drawing of Figure 1.
- the marginal edges 8,8 ' of the semi-circular portions and the lateral sides 9,9' of the lower edges 4,4' are preferably formed flat (in the plane of the panel). Accordingly, panels 2 and 3 can be pivoted around apex 7 so as to bring the panels 2 and 3 toward one another and the edges 8 and 9 may be heat sealed with corresponding edges, 8 ' and 9 ' respectively to form a semi-circular shaped receptacle while leaving the surfaces of panels 2 and 3 unadhered to one another.
- a frangible seal 10, 10' may be provided along the edges 4,4' in the region of the receptacle to house a freatment substance in the receptacle.
- panels 2 and/or panel 3 may be provided with securing means, preferably adhesive strips, which enable removable fixation of the masking sheet to the hair and/or adjacent sheets.
- panels 2 and 3 may be approximated about a pivotable portion 11, 11' provided along edges 4,4' so as to unite the two panels either prior to use or in order to envelop selected strands of hair therebetween.
- the panels 2 and 3 are of substantially equal area, as are receptacle halves 6 and 6'.
- the sheet may be formed in a single operation, or selected components of the sheet may be welded or coextruded to provide the above described features.
- the edges 5,5 ' of the sheet furthest from the hinge 11, 11' define respective upper edge portions of the respective panels of the masking sheet when the panels are approximated as shown in Figures 2 and 3.
- Figures 4-6 shows a sheet subsfrate comprising a receptacle similar to that of Figure 1.
- Figure 4 shows panels 2 and 3, which are of substantially equal area and formed from similar materials as a substrate shown in Figure 1. Panels 2 and 3 are welded to one another along a common edge, or co-extruded, to form a transversly extending hinge 12.
- the substrate shown in Figures 4-6 may comprise one or more securing means, for example adhesive strips by, which the subsfrate maybe secured to selected strands of hair and/or adjacent sheets.
- Two halves of a receptacle 13, 13' are located adjacent the hinge and are formed as a blister, preferably by heat forming.
- the panels 2 and 3 may be approximated by pivotal movement about the hinge and heat sealed to one another to form a reservoir.
- the panels are preferably heat sealed on respective surfaces 14,14'. that surround the respective regions on the panels which form the reservoir.
- Treatment liquid may flow into the receptacle through a mouth portion 15, which opens into the region between the panels. Squeezing a blister 13 which contains a liquid freatment substance will cause the substance to flow out of the reservoir onto panels 2 and 3. If the envelope is closed, that is to say the panels are united and overlie on another, capillary action will allow liquid to flow between panels 2 and 3, thereby increasing the amount of treatment substance on the hair, or replenishing freatment substance after it is drained into the blister.
- sfrands of hair of a head of hair are selected and one of the panels 2 or 3 is place under selected sfrands of hair such that an upper margin 5,5 'of the panel is located adjacent the scalp of the head.
- the selected sfrands of hair may be subsequently coated with a treatment substance, for example a liquid colouring substance and the panel 2 is folded about the hinge 12 and is superimposed on panel 3 with the selected sfrands of hair located therebetween.
- a securing means for example an adhesive strip, is provided, the hair may be contacted with said strip, thereby securing the selected hair between the panels.
- one of the panels preferably the front panel, is transparent, or is provided with a transparent window in the panel, enables a hairdresser to monitor the coloration process of the selected strands of hair without having to remove the envelope 1 from the hair or peal back a panel 2, 3 in order to monitor the process.
- one of the panels is substantially opaque, for example white, this provides a convenient colour over which to view the colouring process.
- Figure 4a shows a -similar sheet substrate to that of Figure 4.
- panel 2 is provided with an adhesive strip 18, adapted to contact and secure to hair sfrands in use.
- Envelope sealing means 16 are additionally provided along the lateral side edges of the panels. These sealing means may be adhesive strips or a mechanical seal such as those found on food bags.
- seal 16 on one of the panels may comprise a raised ridge and the seal 16' on the other panel may comprise a ridge receiving trough.
- the approximation of seal parts 16 and 16' causes the ridge to enter the trough, thereby sealing the sides of the envelope, thereby preventing or reducing leakage of treatment substance.
- Seal 16 is shown running from the edges 5, 5' of the sheet, to the hinge 17, about which the panels 2 and 3 may pivot when surfaces 14 and 14' are sealed together.
- each of panels 2 and 3 may be separately grasped and pulled apart, or the envelope may be scrunched between fingers in order ,to separate panel 2 from panel 3.
- Figure 7 shows a similar sheet to that shown in Figure 6.
- Figure 7 shows a receptacle 13 containing a treatment composition.
- the receptacle is provided with a frangible seal 19 adjacent to the hinge 17 about which panels 2 and 3 may pivot.
- an apertured enclosure 21 is shown having an adhesive strip 22 enclosed therebetween. This feature will be discussed in more detail below in relation to the embodiments shown in Figures 14 to 20.
- the surfaces 14 and 14' are -shown permanently heat sealed together.
- Figure 8 shows a sheet subsfrate 1 having panels 2 and 3, joined by a transversely extending hinge 23 about which each panel may pivot.
- An upper marginal portion 24 of the panel 2 furthest from the hinge 23 is provided with islands of elongate adhesive material 25. These islands extend inwardly from the adjacent margin 24 and channels 26 are provided therebetween. These channels are adapted to facilitate the conveyance of liquid from the central region of the panels toward the edge 24.
- the pressure sensitive adhesive islands are slightly raised on the surface of portion 2, such that a slight space is provided between the panels 2 and 3 adjacent the adhesive islands. The dimensions of this space maybe adapted to optimise capillary action so that the conveyance of liquid towards the margin 24 is maximised.
- the edge 24, and the edges of other masking sheet substrates according the present invention are adapted to abut the scalp during use, are less flexible than the rest of the panels 2 or 3. Such a stiffening of the margin provides greater ease of use and handling.
- the adhesive islands Prior to use, the adhesive islands may be covered with a cover strip (not shown) having a release coating in contact with the adhesive. In use, the cover strip is pealed from the adhesive so as to expose the adhesive ready for use. It will be appreciated that use of a cover strip facilitates stacking of sheets.
- one of the panels for example panel 2 or 3 , is less flexible than the other. This provides a greater support for the selected hair strands in use.
- Figure 9 shows a side vie of the subsfrate shown in Figure 8 formed into an envelope. A gap between portions 2 and 3 is illustrated to emphasise the space, which may exist between the panels of the envelope to facilitate capillary action of treatment liquid located between the portions.
- Figure 10 shows a sheet substrate comprising panels 2 and 3.
- Panel 2 is provided with islands 25 of pressure sensitive adhesive and two substantially parallel sfrips of adhesive 27, 27' the strips of adhesive 27, 27' extend along the respective lateral side edges of panel 2 from panel margin 24, down to hinge 23.
- Adhesive islands 25 and strips 27, 27' may be provided on faces of both panels 2 and 3. In use, as panels 2 and 3 are approximated by pivoting about hinge 23, panel 2 contacts and adheres to panel 3 through adhesive strips 27.
- Adhesive islands 25 maybe used to contact and secure selected hair sfrands between panels 2 and 3.
- Adhesive strips 27 and 27 not only secure panels 2 and 3 together, but further provide a seal against the leakage of any freatment liquids from the envelope in use.
- FIG 11 is a side view of the masking sheet substrate shown in Figure 10.
- the substrate is shown folded so that adhesive strip 27, 27' is almost in contact with adjacent panel 3.
- the adhesive strips and islands may be provided with a cover strip having a release coating in order that the sheets may be stacked, for example, for transport or storage. Further approximation of panels 2 and 3 would lead to contact of the panels by the adhesive sfrips, thus removably securing panel 2 to panel 3.

Strands of hair are received by the gap 39 and moved towards the bottom of the gap, adjacent the base of the teeth 40.
- the hair is forced together and becomes removably trapped in the gaps.
- This provides a securing means.
- adhesive may be provided in order to approximate panel 2 with panel 3 so as to envelop selected strands.
- the size of the gaps between the teeth may be adapted in order that an approximately predetermined amount of hair is trapped therebetween. This may be used in order that a predetermined amount of treatment substance maybe made up and applied to the hair in the knowledge that the amount of treatment substance used is sufficient to treat the amount of hair gathered by the teeth.

- the adhesive strip 120 extends from one side of the panel 112 to the other slightly inward of an upper edge 122 of the panel, opposite common edge 116, so that an adhesive free region 124 is defined between the edge 122 and the adhesive 120.
- An upper edge portion 126 of the panel 114, opposite the common edge 116, has a stiffness greater than the remainder of the panel 14 so that the edge portion 126 does not distort when the sheets are separated from each other in readiness for use.
- the increased stiffness of the edge portion 126 is provided by increasing the thickness of the edge portion 126, for example by providing an additional layer of the same sheet material along the edge portion 126 to double the thickness and stiffness of the edge portion.
- the additional layer is preferably provided by folding the longitudinal edge of the panel 112 on itself along a longitudinal fold line at the edge of the panel as shown in the drawing of Figure 2.
- the dimensions of the edge portion 126 are preferably such that it completely overlays the adhesive strip when the panels are brought together.
- the panels may be hinged about the common edge 116 so as to unite the two panels, either prior to use for ease of storage and/or transportation, or in order to envelop selected sfrands of hair in use. Similarly the panels may be hinged apart to separate the panels in readiness for use to receive selected sfrands of hair between the panels.
- the panels 112 and 114 Prior to use, the panels 112 and 114 are separated in readiness for use by releasing the upper .edge portion 126 from the adhesive 120 holding the panels together.
- the adhesive free region 124 provides a finger tab for the overlying edge portion 126 so that the panels can be more easily separated.
- the stiffness of the edge portion 126 is such that the action of releasing the edge portion from the adhesive strip occurs without distortion, notably curling, to the upper edge portion due to stretching of the surface of the edge portion in contact with the adhesive.
- strands of a head of hair to be treated are selected by the hairdresser and the panel 112 is positioned under the strands in a known manner such that the adhesive strip 110 is located adjacent the scalp of the head.
- the adhesive adheres to the selected sfrands, which are then coated by the hairdresser with a treatment solution, for example a liquid colouring substance.
- the panel 114 is then folded over panel 112 about the common fransverse hinge and brought into proximity with panel 112 to close the envelope so formed ⁇ as indicated in the drawing of Figure 2.
- Panel 114 is held with respect to panel 112 by cohesive forces acting on panel 112 due to the surface tension of the treatment solution on the panel 114.
- panel 114 is transparent enables the hairdresser to monitor the coloration process of the selected strands of hair without either having to remove the masking aid from the hair or peel back the panel 114 to monitor the process.
- the other panel 112 is opaque, for example white, this provides a convenient colour over which to view the colouring process.
- panel 114 may be considered a front panel and panel 112 a rear panel when the masking sheet is folded in the closed configuration of Figure 40.
- the masking aid comprises an additional intermediate rectangular panel 130 of substantially transparent material.
- the panel 130 is substantially identical to panel 114 and comprises a substantially transparent polyolefin or polyester flexible sheet material.
- Panel 130 is joined to panels 112, 114 in substantially the same way that panels 112 and 114 are joined together, that is to say along common edge 116 by welding or other means to form a common transversely extending hinge about which all three panels may be pivotally moved with respect to one another.
- the panels are arranged with respect to one another so that they may be superimposed one on top of the other when they are brought together.
- the panel 130 enables additional sfrands of hair to be selected for freatment in addition to the selected strands enveloped between panel 112 and 114. Additional sfrands are selected once the freatment solution has been applied to the selected sfrands between panel 112 and intermediate panel 130 and the panels have been closed.
- the hairdresser may apply a different treatment solution, for example a different liquid coloration substance, to the additional sfrands and then envelop the additional strands between panels 114 and 130 by bringing the panels together.
- a different treatment solution for example a different liquid coloration substance
- thepanels 112 and ll4 arej inedtogetherbyadhesive.
- the first panel 112, shown in Figure 43a is provided with an additional adhesive strip 132 for joining the panels together.
- the adhesive strip 132 is substantially U-shaped and extends transversely along the common edge 116 of the panel 112 and part way along the lateral side edges 134 and 136 of the panel away from the edge 116.
- the adhesive strip 132 is provided on the same side of the panel as the adhesive strip 120.
- the adhesive strip 132 may be 5mm wide along the major portion of the edge 116, may be 10mm wide along the lateral side edges 134 and 136 and extend, say, 30mm along the edges 134 andl36 away from the edge 116. These dimensions readily enable the panels 112 and 114 to be hinged apart when joined together by the adhesive strip 132.
- the width of the adhesive strip 120 may be 12mm and the width of the gap 124 may be 3mm.
- the first panel 112 comprises a metalised polyester flexible subsfrate sheet material.
- the second panel 114 shown in Figure 43b comprises a rigid clear film material, preferably a transparent polyester material, that is coated with an ink or other suitable coating in the region 138 adjacent to the edge 116 of the panel 114.
- An uncoated triangular shaped part 140 is provided in the centre of the coated region 138 with the apex of the triangle positioned closest to the edge 116 of the panel.
- the triangle 140 provides a transparent window in the panel in the coated edge region 138.
- the U-shape adhesive strip 132 of the panel 112 partially surrounds a region 142 adjacent to the edge 116 of that panel.
- the partially enclosed region 142 provides a reservoir for holding treatment solution in use.
- the printed region 138 overlies the reservoir region 142 so that, in use, the contents of the reservoir can be viewed through the window 140.
- the edge portion 126 of the front transparent panel 114 may have a greater stiffness than the remaining part of the panel.
- an additional intermediate panel 130 is shown, which, in a further embodiment of the present invention, is provided between the panels shown in Figures 43a and 43b.
- Intermediate panel 130 is substantially identical to panel 114 but instead of the printed region 138 the panel comprises a U-shaped adhesive strip 144 substantially the same as the adhesive strip 132 previously described with reference to the rear panel of Figure 43a.
- the adhesive strip joins the intermediate panel 130 to the front panel 114 in the same way that the adhesive strip 120 joins the rear panel 112 to the intermediate panel 130 along the common edge 116 so that the panels may be pivotally moved with respect to one another.
- the panels 112, 114 and 130 have the same or similar external dimensions and are shown schematically in Figure 43d in a partial overlapping relationship.
- FIG. 43 d the individual panels shown in Figure 43 d are arranged one on top of the other when they are joined together with the panels effectively superimposed on one another.
- more than one additional (or intermediate) panel 130 may be provided in a masking aid of type described with reference to Figures 43a to 43c.
- two additional panels maybe provided so that the masking aid comprises four panels mutually joined together along a common hinged edge so that three regions are provided for separately treating different strands of hair.
- the front panel 114 is divided into two parts 114a and 114b between the upper edge portion 126 and the common edge 116 to provide two separate regions for receiving separate sfrands of hair and different colouring solutions.
