Hair treatment foil and method

Abstract

A web roll of flexible foil used in the chemical treatment, of hair, the roil comprising a front face and a back face, a continuous band of pressure-sensitive adhesive deposited on the front face and parallel to and away from an edge of the roll, the back face comprising a continuous deposit of release coating, the release coating allowing ready, tear-free separation of the back face from the front face when the front face and the back face are in contact. Disclosed also are novel design foiling methods on the diagonal utilizing the improved foil.

I claim: 
     
         1 . A web roll of flexible foil sheeting used in the chemical treatment of hair, the sheeting comprising a front face and a back face, a continuous band of pressure-sensitive adhesive deposited, in a machine direction, on the front face and parallel to and a distance away from a leading edge of the sheeting, the back face comprising a continuous deposit of release coating, the release coating allowing ready, tear-free separation of the back face from the front lace when the front face and the back face are in contact, the leading edge defined as the edge that a colorist folds back and places on a scalp when a desired size section of sheeting is torn from the web roll in use. 
     
     
         2 . The roll per  claim 1  further comprising a plurality of spaced apart perforations such that tearing at each perforation presents a section of sheeting that is a foil sheet of a specified size, each foil sheet comprising a band of adhesive at a distance away from and parallel to a leading edge of the sheet the leading edge folded back and placed on the scalp during a chemical treatment of hair. 
     
     
         3 . The web roll per  claim 1  wherein the distance equals one inch. 
     
     
         4 . The roll per  claim 1  wherein the pressure-sensitive adhesive is applied in a direction parallel to a machine direction during manufacturing of the roll. 
     
     
         5 . The roll per  claim 1  wherein the pressure-sensitive adhesive is applied in a direction that. is perpendicular to a machine direction during manufacturing of the roll. 
     
     
         6 . The roll per  claim 1  wherein the roll is treated with a tint that is true color. 
     
     
         7 . In a chemical treatment for hair, a method for performing balayage comprising the following steps;
 a. Bringing to a treatment work area a plurality of sheets of foil each sheet comprising a front face and a back face, a continuous deposit of a hand of pressure-sensitive adhesive on the front face of the sheet and a distance away from and parallel to a leading edge of the sheet, a release coating on the back lace of the sheet,   b. Sectioning hair in preparation for balayage,   c. Selecting a first section of hair for chemical treatment,   d. Picking up a first sheet of foil and folding back on its leading edge at approximately a top edge of adhesive, place the first sheet of improved foil under the first section of hair with the adhesive side up and away from the scalp,   e. Applying a treatment chemical to a surface of the first section of hair selected for treatment from approximately mid-hair shaft to hair ends, without folding the first sheet, where the treatment chemical is not 40 Volume Developer,   f. Placing a second sheet of improved foil over the first sheet such that the adhesive on the first sheet and the adhesive on the second sheet face each other and touch or kiss each other creating a foil sandwich and   g. Iteratively repeat steps b through f above until a desired number of hair sections has been treated.   
     
     
         8 . A method for design foiling of a head of hair comprising the following steps:
 a. Bringing to a treatment work area a web roll of foil sheeting, the sheeting comprising a front face and a back face, a continuous deposit of a band of pressure-sensitive adhesive on the front face and a distance away from and parallel to a leading edge of the sheeting, a release coating on the back face,   b. Selecting an approximate one inch first section of hair just over the top of a first ear,   c. Tearing off an approximate one inch section of sheeting from the web roll and placing it over the first section of hair, the adhesive side facing the scalp and   d. Iteratively sectioning off additional sections of hair, foiling and treating the hair working toward the crown of the head and applying, underneath each additional section of hair, adhesive side facing the scalp, a progressively larger section of sheeting tom from the web roll and   e. Repeating steps b through cl above on the opposite side of the head.
