Definitions

  • the present invention relates to a process for treating hair fibres.
  • a device which makes it possible to apply a cosmetic product to the hair, to expose the latter to steam, to subject said hair to heat treatment and to comb it is known from international application WO 2014/064660 .
  • the comb is placed downstream of the member for applying the cosmetic product and the combing step is therefore carried out after the product application step.
  • the invention aims to meet this need, according to a first aspect, by means of a process for treating hair fibres, comprising:
  • this makes the treatment of the hair fibres easier by facilitating the movement of the tool(s) carrying out the process along the hair fibres, in particular by decreasing the force which the user must exert in order to deposit a predetermined amount of product.
  • hair fibres denotes human keratin fibres such as the hair or synthetic fibres known as "extensions" which are added to an individual's head of hair by various means, in particular by adhesive bonding, this being in order for example to modify the appearance of an individual's natural head of hair.
  • the steps of the process can be carried out by at least two different tools.
  • the combing step (i) and the step of applying a hair product (ii) are carried out using a single tool.
  • all the steps of the process can be carried out using a single tool, in particular using a device for shaping the head of hair configured to carry out the various steps successively in the same portion of hair fibres.
  • the steps of the process are carried out by moving the tool(s) along a lock of hair fibres.
  • Step (iv) of heat-treating the hair fibres can be carried out using a hair smoothing iron.
  • the process of the invention makes it possible to improve the smoothing of the hair, in particular to decrease the hair volume.
  • steps (i) and (ii) are carried out, for example, during the same session at the hairdresser, with a period between them of less than or equal to 5 min, better still less than or equal to 1 min, even better still less than or equal to 30 s, preferentially less than or equal to 15 s, and more preferentially less than or equal to 5 s.
  • all the successive steps are carried out with a period between them of less than or equal to 5 min, better still less than or equal to 1 min, even better still less than or equal to 30 s, preferentially less than or equal to 15 s.
  • the process is preferably free of any combing step after step (ii) within a period of 15 s.
  • the process comprises a single combing step.
  • the fact that there is only one combing step makes it possible to simplify the process without the efficiency of the treatment being affected thereby.
  • step (iv) is carried out after step (ii), in particular less than 5 min, better still less than 1 min, after step (ii), even better still less than 30 s, preferentially less than 15 s, after step (ii).
  • step (iii) is carried out after step (ii) and before step (iv), in particular less than 5 min, better still less than 1 min, even better still less than 30 s, preferentially less than 15 s, before step (iii) and after step (ii).
  • the heat treatment can be carried out by contact of the hair fibres with hot surfaces, in particular hot surfaces applying to the hair a tension that makes it possible for example to smooth, style or disentangle the hair fibres.
  • the heat treatment can be carried out at a temperature greater than or equal to 90°C, preferably greater than or equal to 120°C, more preferably greater than or equal to 140°C, even more preferably greater than or equal to 170°C, and/or less than 230°C, preferably less than 220°C, more preferably less than 210°C; the hot surfaces are preferably brought to such temperatures.
  • the amount of steam applied during step (iii) can be greater than or equal to 1 g/min, preferably greater than or equal to 2.5 g/min and less than or equal to 60 g/min, preferably less than or equal to 30 g/min, preferably less than or equal to 10 g/min, more preferably less than or equal to 6 g/min, and even more preferably less than or equal to 4.5 g/min.
  • the steam applied to the hair fibres during step (iii) may contain one or more cosmetic ingredients and/or active agents such as a fragrance, and/or a hair shaping and/or conditioning active agent.
  • composition applied to the hair fibres is preferably in the fluid state during the application.
  • the composition may be aqueous or anhydrous.
  • the composition may comprise at least one ingredient chosen from solvents, surfactants, thickeners, preservatives, fragrances, dye precursors, direct dyes, silicone or non-silicone and fixing or non-fixing polymers, fatty substances, in particular mineral, vegetable or synthetic oils, and waxes, reducing agents, oxidizing agents, UV screening agents, conditioning agents, agents for combating free radicals, sequestering or stabilizing agents, antioxidants, acidifying agents, alkaline agents, volatile or non-volatile silicones, reactive or chemically inert polymers, pigments, solid organic or inorganic particles, vitamins, plant extracts, or propenetrating agents or fibre-swelling agents.
  • solvents solvents, surfactants, thickeners, preservatives, fragrances, dye precursors, direct dyes, silicone or non-silicone and fixing or non-fixing polymers, fatty substances, in particular mineral, vegetable or synthetic oils, and waxes, reducing agents, oxidizing agents, UV screening agents, conditioning agents, agents for combat
  • the composition is a hair fibre care composition.
  • the step of applying the composition can be followed or preceded by rinsing, by a step of washing the fibres, by a step of hair shaping or controlling the shape, for example using a fixing gel, a hair shaping mousse, a lacquer or a leave-in conditioner in cream form, by a step of permanent, semi-permanent or temporary dyeing, by a step of permanent deformation using a reducing agent and optionally a fixative, by a step of alkaline straightening, in particular with sodium hydroxide or with guanidine carbonate.
  • a subject of the invention is a process for treating hair fibres, comprising:
  • the process may, according to this aspect of the invention, optionally comprise a step (iii) of treating the hair fibres by applying steam.
  • the process comprises four successive steps 10, 12, 14 and 16 carried out on a lock of hair fibres by a device for shaping the head of hair.
  • the device is configured to perform the various steps of the process successively on the hair fibres, by movement of said device along the lock of hair, in particular over a portion of the hair fibres inserted between two arms of said device, forming an iron.
  • Step 10 is a step of combing the hair, making it possible to separate the hair fibres, before applying a composition in step 12.
  • the application of the composition 12 is preferentially carried out immediately after step 10.
  • the hair fibres are then subjected to a steam treatment 14 which is carried out immediately after step 12.
  • the hair fibres are subjected to a heat treatment 16 intended to smooth them. They are brought into contact with hot plates, in particular each arranged on one arm of the device, between which they are held tight.
  • composition 12 can be carried out using an applying member placed on one of the arms and which holds the portion of hair fibres undergoing treatment tight against a counter-bearing surface of the other arm.
  • the application of composition 12 can be carried out using two tools, in particular an applying member and a member for distributing the composition on the hair fibres.
  • Steps 10 and 12 can be carried out with a same device, for example a comb or a hairbrush applying the composition
  • steps 14 and 16 can be carried out by a same device, in particular a smoothing device, or by two distinct devices, in particular a device for applying steam and a device for smoothing the hair.
  • a first device suitable for the treatment according to the invention is used on locks of natural hair of Caucasian type, having type IV curliness.
  • composition A INCI Name % by weight AMODIMETHICONE (and) TRIDECETH-6 (and) CETRIMONIUM CHLORIDE (1) 1.0 PEG-40 HYDROGENATED CASTOR OIL 0.8 DIMETHICONE (and) LAURETH-23 (and) LAURETH-4 (2) 5.0 BEHENTRIMONIUM CHLORIDE 1.0 STEARYL ALCOHOL 1.5 Active agents 0.12 Fragrance 0.2 Preservative 0.9 Water qs 100 (1) XIAMETER MEM-8299 EMULSION sold by the company DOW CORNING (2) XIAMETER MEM-2664 EMULSION sold by the company DOW CORNING
  • the locks are then subjected to steam with a flow rate of approximately 3.5 g/min, then the locks are pinched between two plates of the device, heated to a temperature of200°C.
  • a second device is used on locks of hair of the same type as previously. This device makes it possible to carry out the same steps as previously, but the combing step is carried out after the application of the product.
  • the combing force is measured using a tensile testing machine, in particular a Lloyd LS1® with a 50 N sensor, by measuring the mechanical strength of the device by passing over a lock of hair.
  • Table 2 Combing force measured for the first and second devices, at equivalent amount of product applied COMBING FORCE / APPLICATION (a.u.) Condition Mean Standard deviation Second device 3807.8 1126.9 First device 1356.1 413.6
  • Carrying out the combing step before the applying step facilitates the movement of the device along the lock of hair while preserving good composition application.
  • a first device suitable for the treatment according to the invention is used on a lock of natural hair of Caucasian type, having type IV curliness.
  • the lock is combed by passing through a comb and then composition A is applied to the lock by pinching the latter between an applying member and a counter-bearing surface.
  • the lock is then subjected to steam with a flow rate of approximately 3.5 g/min, and then it is pinched between two plates heated to a temperature of 200°C.
  • the above treatment is carried out by passing the device along the lock of hair for a period of 15 s.
  • a second device is used on a lock of hair of the same type as previously.
  • This second device makes it possible to carry out the same steps as previously, but the combing step is carried out after the application of the composition.
  • the treatment time is the same.
  • a commercial smoothing device in this case a Styler® ghd gold classic, is used on a lock of hair of the same type as previously.
  • This smoothing device does not comprise any combing means and means for applying the composition. It is passed along the lock of hair 3 times, each pass lasting 8 s.
  • the locks of hair used for these various treatments are from the same batch.
  • Figure 3 presents four locks of hair.
  • the first lock 20 starting from the left is a lock of hair of the type previously described, which has undergone no treatment.
  • the second lock of hair 22 is a lock of hair of the same type, which has been treated with the first device.

  • the first device performs two passes lasting 15 s over the lock of hair.
  • the lock of hair passes through a commercial smoothing device, in this case the Styler® ghd gold classic previously used.
  • This smoothing device makes it possible to pinch the lock of hair between two plates heated to a temperature of 190°C. It is passed along the lock of hair twice, each pass lasting 15 s.
  • a second treatment is carried out on a lock of hair of the same type as previously.
  • the second treatment is identical to the first, except that the applying step is carried out with a second device.
  • the latter makes it possible to carry out the same steps as previously, but the combing step is carried out after the application of the composition.
  • the treatment time and the number of passes over the lock of hair are the same.
  • the combing force as a function of the amount of product applied is determined by measuring the resistance of each device to the passing over a lock of hair using a tensile testing machine, in particular a Lloyd LS1® with a 50 N sensor. The measurements are taken for each applying and smoothing step.
  • the measurements are taken on three different locks of hair of the abovementioned type.
  • Carrying out the combing step before the applying step facilitates the movement of the devices along the lock of hair while preserving good composition application.
