WNWNTION TITLE: 'An improved hair piece and a method of attaching a hair piece to the head of a person' The following statement is a fall description of this invention, including the best method of performing it known to us: ~g~l la I "AN IMPROVED HAIR PIECE AND A MEIOD OF ATFACHING A HAIR PIECE TO THE HEAD OF A PERSON" This invention relates to an improved hair piece and to a method of fiting a hair piece to the head of a person.

I The applicant's Australian Patents 495956 and 578904 describe apparatus and methods for attaching a hair piece to the head of a person. Australian patent 495956 describes a method of attaching a hairpiece wherein groups of strands of glandular hair are pulled through apertures in the ribbon portion of the -i 30 foundation of the hair piece. These groups of strands of glandular hair are Ssubsequently knotted together and a bonding agent applied to the knot The S.j. bonding agent serves to prevent the strands from unknotting and to hereby

T

It -2maintain the hair piece in position on the wearer's head SA aian patent 578 teaches another method of attaching a hair piece to As78904e patted 578904r metho the head of a person. In this method the hair piec is fitted with a plurality of deforab elongated tubes along the peripheral ribbon of the hair piece.

Strands of glanduar hair are passed through the tubular elements and then each tubular element is deformed In this way the strands of glandular hair are retained in the tubular elements ad the hair piece is ixed the wearer.

2 10 10Althogh the methods decribed in both of the applicant's previous patents are advantageous over the prior art methods they suffer the disadvantage that the advantageous hair piece is only attached to the head of the wearer at a number of discrete locations This means that if any stress is applied to the hair piece this stress the e e c n ehair piece in is transmitted to the few strands of glandular hair that hold to the position. Thus, any stress placed on the hair piece can cause discofo the t a p the hair piece l al b e aue wearer because the glandular hai secring the hair piece wil be pued.

Another problem with these methods of connection is that the majority of the Another problem with 'he n o the head of the wearer and thus periphery of the hair piece is not cnnected to thethe he ad of the wearer the hair piece may not sit firmly, nor does i sit fat against the head of the wearer. This sometimes means that the hair piece looksunnatural because it does not blend sufficiently well with the glandlar hair of the wearer.

Another problem with conventional hair pieces and their method of 25 attachment is that in areas such as the forehead where there is no glandular hair, the transition between the scalp of the wearer and the foundation of the hair piece can be quite obvious.

It is an object of the present invention to provide animproved method of 30 attaching ahair piece to the head of the wearer. The invention also e provide a softer transition between the scalp of the wearer and the hair piece itself in areas of the head where there is no glandular hair.

-3- According to a first aspect of the present invention there is provided a method of fixing a hair piece to the head of a person, said hair piece comprising a centre portion which is surrounded by an adherent track, said method comprising: a) adhering a first portion of the adherent track of the hair piece to a portion of glandular hair of the person's head; and b) securing the remaining portion of the adherent track to the head of the person by positioning adherant or double sided adhesive means between the head of the person and the hair piece.

According to a second aspect of the present invention there is provided a method of fixing a hair piece tu dte head of a person, said hair piece comprising a centre portion which is surrounded by an adherent track, said method comprising: a) adhering a first portion of the adherent track of the hair piece to a portion of glandular hair of the person's head; b) attaching strands of hair to an area of the person's head over which the hair piece has not already been adhered, but which lies beneath the hair piece when it is positioned on the person's head; and c) securing the hair piece over the strands of hair and to the person's head using double sided adhesive means or another mechanism so that the strands of hair are positioned between the scalp of the person's head and the hair piece and so that the unattached ends of the strands of hair extend out beyond the periphery of the hair piece so as to soften or disguise the connection between the scalp and the hair piece.

Preferably, the portion of glandular hair on the person's head is formed by portion of the person's head.

Preferably, adherent is applied to the line or the track of glandular hair on the person's head and on a portion of the adherent track which is arranged to lie over said line or track of glandular hair when the hair piece is positioned on the person's head.

Preferably, strands of hair are adhered to the scalp or to hair stubble on the area of the person's head to which the hair piece is not already adhered. The strands of hair are attached on an area of the person's head which is bounded by a line coincident with the periphery of the adherent track of the hair piece when it is positioned on the person's head.

15 An embodiment of the invention will now be described by way of example only with reference to the accompanying drawings in which:- Figure 1 is a plan view of a foundation of a hair piece; Figure 2 is a side view of a man to whom a hair piece is to be attached; and Figure 3 is the front view of another man to whom a hair piece is to be attached.

Figure 1 shows a ha;r piece comprising a foundation 10 having natural or synthetic hair attached thereto. The foundation 10 comprises a central net portiin 12 and a peripheral adherent track 14. The foundation 10 and the adherent track 14 are dimensioned such that when the hair piece is placed on the wearer's head the adherent track 14 is located over a region of glandular hair 16 on the weaer's head.

A preferred method of the attaching the hair piece to a wearers head will now

LA

Ct4A be described with reference to Figure 2. The first step in the method is to ensure that the hair piece chosen for the wearer is of the correct size. Once the correct size of hair piece has been chosen the wearer's head must be marked to show the exact position of the periphery 18 of the foundation when the hair piece is correctly positioned on the wearer's head. The exact position of the hair piece on the wearer's head can be marked using a wax pencil. A line 19 is drawn with the wax pencil just inside the line of contact of the neripheri 13 of the foundation 10 on the wearer's head- Using this line 19 as a guide, clippers or scissors can be used to trim the hair above the line 19.

Thbis area of trimmed hair forms a track 20 of glandular hair. It is over track that the adherent track 14 of the hair piece is subsequently adhered. The hair of track 20 should be trimmed to a fine stubble so as to ensure good bonding between the adherent, the hair stubble of track 20 and the adherent track 14. The track 20 of glandular hair should be of a width similar to the width of the adherent track 14 on the foundation 10. Track 20 should extend, where possible, around the wearer's head. As shown in Figure 2 the track extends fro m temple to temple of the wearer.

The wearer's head is then cleaned with an appropriate solution, e.g. alcohol to ensure proper bonding between the track 20 of glandular hair, the scalp and the hair piece.

A smnall amount of adherent is then applied to the track 20 of glandular hair and to the adherent track 14 of the foundation 10. Adherent on the track of glandular hair should be applied Using a back and forth motion. The final brush stroke of adherent on the track 20 should be made in the direction of hair growth. This will ensure the wearer's comfort as the hair grows.

Using the line 19 as a guide the hair piec%- is positioned onto the wearer's head with the adherent track 14 overlying the track 20 of glandular hair. Gentle pressure should be applied to the area of the track 20 so as to ensure a good bond between the scalp, the glandular hair and the hair piece.

g- -6- In Figure 1 the portion of the adherent track 14 which is actually adhered to the track 20 of glandular hair is the cross-hatched portion labelled as 14a.

Portion 14a of the adherent track 14 is of a length sufficient to surround the wearer's head from temple to temple. The portion of the adherent track 14 which is not adhered to the wearers head is labelled as portion 14b. If the hair piece was attached to the wearer shown in Figure 2, the portion 14b of the adherent track would be positioned over the forehead area of the wearer.

This part of the hair piece (the front part) is conventionally attached to the wearer's scalp using double sided adhesive tape.

When the front part of the hair piece is attached to the head using adhesive #i.4 tape the underside of the foundation 10 lies against the scalp of the wearer's head. One problem with this type of connection is that there is a rapid transition between the bald forehead area of the wearer and the foundation I15 of the hair piece. This generally provides an unnaturally hard hairline. This hard hairline effect can be quite noticeable on some hair piece wearers and Sthus can make the hair piece look unnatural. To overcome this problem strands of hair can be attached to the scalp area above the forehead and arranged so that they extend outwardly between the scalp and the underside of a 20 the foundation 10 of the hair piece.

If strands of hair are to be applied to the scalp area above the forehead the hair piece must first be attached to the wearer's head as previously described.

With the hair piece attached to the wearer's head along the portion of the adherent track 14a the unadhered portion of the hair piece is placed in position on the wearer's head. A second line 22 (Figure 3) is then drawn with a wax pencil just inside the periphery of the unadhered portion 14b of the I adherent track 14. In the examples shown in Figures 2 and 3 this line would extend above the forehead from the right hand temple of the wearer to the left SI 30 hand temple. The line 22 defines a limit over which adherent may not be Sapplied.

A typ 26. Area 26 is bounded by is applied is shown in Figure 3 and labelled as oaude of he line 22 and line 23. Adherent should ot a lied er line 22 because any adherent positioned outside the line 22 willbe visible when the hair piece is in position.

With the adherent placed on the area 26 strands of n be a rrangched on the area. In Figure 3 a group of hair standS 28 are shown attached to area S26. he hair can be arranged in any manner but it should be done with a view that the hair should look as realistic and as natural as possible. It should be that the hair should look eis to soften the transition'line remembered that the function of this hair is to soften the trasition lie between the scalp and the underside founatl loo t he final layer hair has been attached to the area 26 to provide a natural oo e ina ae of adherent should be applied. When the adherent is dry double sided tape used to secure the front part of the hair piece over the strands of hair e strands of hair are thereby positioned between the wearer's scalp and the underside of the foundation 10. Once the hair piece is properly secured over the strandsid of hair the strand can be cut and styled to a natural appearance.

20 These strands of hair are generally lighter and finer in texture used in the hair piece.

hough it is possle to adhere the strands of hair directly to the scalp of the wearer it is preferable if there is some stubble or fine hair othe area 26 The strands of hair will adhere better t stubbhlle or fine hair than if ust adhered to the scalp itself. Depending on the lifeshould reai attached theor amount of hair on area 26 the strands of hair should remain attached for amount of hair on area 26 the strands should around 2 weeks. The attachment of the hair piece along track 20 should remain secure for between 3 to 6 weeks. The time period over which the hair 3 perem ai secure thrack 20 depends greatlyonhe rate at the piece rmans securif the growth of glandular hair is fast it will be necessary glandular hair grows If the to reattach the hair piece more often.

i9 15 f-'f i 2i ~w i- To remove the hair piece it is simply lifted away from the head of the wearer and clippers inserted therebetween to cut the hair piec away from the glandular hair. Once this is done the hair piece must be properly washed ready for reattachment. Meanwhile any adherent left on the client's hair and scalp should be removed using a suitable solvent. This solvent should be worked along the perimeter of the glandular hair rather than into the body of the hair itself. If sufficient hair growth has occurred a new track 20 should be cut into the wearer's hair. The hair piece can then be attached in the manner described previously. It is optional to leave a small area 30 of the adherent track 14 unattached to the scalp. This area 30 would generally be positioned at the back of the hair piece and provides a drainage area through which shampoo etc. may drain from betwee' the scalp and the underside of the foundation The method of attachment described herein is particularly advantageous because the hair piece is attached along a continuous track This provides a more secure attachment and makes the hair piece more comfortable to wear.

This comfort arises because any stress applied to the hair piece is transferred to a greater areaof the scalp rather than to individual hairs as with previous attachment methods. Furthermore, the attachment of the hair piece is such that the hair piece is more securely fitted to the head and is shaped to sit against the scalp of the wearer. This provides a more natural appearance for the hair piece. The individual strands of hair placed along the front hair line soften the transition between the scalp and the underside of the foundation.

lthogh the embodiment of the invention described herein teaches adhering the individual strands of hair to an area above the forehead, these strands could be fitted to any other area of the scalp where there is hair loss.

Te embodiment has been described by way of example only and modificatio are possible within the scope of the invention.
