Definitions

  • the present invention relates to a method and apparatus for use in treating selected strands of hair and particularly, but not exclusively, to a method and apparatus for use in the colouring of selected strands of hair.
  • strands of flexible material for isolating selected strands of hair daring a process of hair treatment such as colouring.
  • strands of hair to be coloured are first selected by a hairdressing technique known as weaving. These strands of hair are then laid over a length of liquid impermeable material which effectively isolates the selected hair from the remaining hair.
  • the barrier material will generally have a width of 2 or 3 inches (i.e. between 5 and 8 cm) and a length at least equal to that of the hair to be treated.
  • One edge of the material is located adjacent me roots of the selected hair strands and in contact with the scalp. The hair roots are then pressed onto a portion of the material provided with a contact adhesive.
  • the material is thereby retained in position on the scalp during the hair treatment process.
  • an appropriate hair treatment substance may be applied to the selected strands of hair.
  • the scalp and remaining hair strands are protected from exposwe to the hair treatment substance by means of the barrier material.
  • Prior art documents WO 97/38602. and FR 2 585 565 disclose hair treatment apparatus comprising a substrate provided with a plurality of hook elements for gripping selected strands of hair and retaining the substrate in position Once a hair treatment substance has been applied to the selected hair stands, the substrate is folded so as to encapsulate the selected hair strands and mask the hair strands from the remaining head of hair. However, the substrate is retained in the folded position-by means of the inherent stiffness of the substrate material and/or by means of the surface tension of the hair treatment substance.
  • a further prior art apparatus for the treatment of hair is disclosed in US 5,664,590. This further prior art apparatus comprises first and second substrates which overlie one another and are connected along one edge so as to be hingedly movable relative to one another. One surface of the first substrate is entirely covered with hook fasteners whilst a mating surface of the second substrate is entirely covered with loop fasteners which, in use, cooperate with the hook fasteners.
  • the present invention seeks to solve certain problems with the presently known hair treatment apparatus and process.
  • use of the prior art apparatus can be problematic since a practitioner will often cause the adhesive on the barrier material to contact surfaces (such as the scalp, the hair ends rather than the hair roots, or the barrier material itself) by mistake.
  • Further use of the apparatus will require remedial action in order to free the barrier material from the surface to which it has been mistakenly attached.
  • subsequent use ofthe.apparatus will not be possible and the apparatus will be disposed of without having been used. Even where further use of the apparatus is possible, the effectiveness of the contact adhesive will often have been reduced by its previous surface contact.
  • the prior art apparatus can therefore lead to a time consuming and wasteful hair treatment process.
  • the prior art apparatus do not tend to adhere effectively with greasy types of hair.
  • it will very often be necessary to wash hair to be treated before use of the aforementioned prior art apparatus. Again, this leads to a time consuming process.
  • the adhesive will of course only secure to the barrier material those strands of hair which it contacts.
  • selected strands of hair will very often overlay further selected hair strands in contact with the adhesive and, accordingly, not themselves be secured to the barrier material. This can lead to an increased risk of hair treatment substance bleeding onto the scalp.
  • the problems with the prior art apparatus also include the difficulty of selecting a barrier material from a store of such materials.
  • barrier materials are generally sold in cartons as tightly packed individual barrier materials.
  • the user is presented with a plurality of barrier materials which are pressed closely together and not readily removable.
  • removal of the materials from the carton can lead to the materials becoming misplaced and is not conducive to good order.

  • the portion of hooked material 406 adhered to the base sheet 404 is that portion of hooked material 406 located between the upper edge 409 of the base sheet 404 and dotted line 410 shown in Figure 12. It will be apparent to the skilled reader that this feature can be employed on any of the previously described embodiments and other arrangements.
  • a strip of fibrous, or, in accordance with the present invention, hooked, material 411 is secured by means of a suitable adhesive adjacent the lower edge 413 of the base sheet 404.
  • the lower strip of material 411 will engage the upper strip of material 406 and become connected therewith This connection not only assists in retaining the base sheet 404 in a folded position, but also assists in preventing hair treatment substances from undesirably leaking onto the scalp.
  • the fibres of said material may be looped or, ideally, have a free end.
  • FIG. 13 A partial plan view of the strip of hooked material 406 is shown in Figure 13 of the accompanying drawings.
  • the enlarged view of Figure 13 shows that the hooked material 406 is provided with a plurality of circular mushroom shaped hook members 414.
  • the hook members 414 are arranged in a plurality of columns which run parallel to the longitudinal axis 415 of the base sheet 404.
  • strands of hair may locate between columns of hook members 414 without being bent or kinked. In other words; strands ofhair may assume a straight form whilst lying between adjacent columns ofhook members 414.
  • each hook member 414 has a flat planar upper surface 417.
  • each hook member 414 has a head 416 with a conical upper surface 418.
  • the upper surface may be part spherical as shown in Figures 3 and 4. The use of a curved or otherwise sloping upper surface assists in locating hair strands between the hook members 414.
  • said upper surfaces 418 of the hook members 414 serve to guide hair strands towards the gap between the hook members 414.
  • the strip of hooked material 406 shown in Figures 13 to 15 may be substituted with the further modified strips of hooked material shown in Figures 16 to 18 of the accompanying drawings.
  • the hooked material shown in Figures 16 to 18 comprises a plurality of elongate T-shaped hooks 420.
  • the formation of the hook members 420 is such that an elongate T-shaped groove 422 is formed between adjacent hook members 420 which extends parallel to the longitudinal axis 415 of the base sheet 404 and extends from an upper edge 423 of the hooked material to a lower edge 424 thereof Since the grooves 422 are straight, strands of hair may be retained in a straight form between adjacent elongate hooks 420.
  • the heads of the hook members 420 has be provided with sloping upper surfaces 423 for guiding hair strands towards a groove 422.
  • the lower strip of material 411 In order for the lower strip of material 411 to connect with a strip of hooked material 406 comprising the elongate hook members 420 shown in Figures 16 to 18, the lower strip of material should preferably be provided with a plurality of hook members in accordance with the present invention (for example, mushroom shaped hooks or elongate T-shaped hooks). Such hook members are more likely to securely connect with the elongate T-shaped hook members of the hooked material than loops or other fibrous material.
