Abstract
Abstract Human hair is highlighted by a procedure in which the hair initially is moistened with water and towel dried. The hair is then teased and on the teased hair is sprinkled a dry powder bleach mixture which sifts downward through the hair. A mist of a solution of hydrogen peroxide is applied to the dry powder bleach mixture and thereafter the hair is rinsed and shampooed. The final rinsing and shampoo takes place within five minutes following application of the solution of hydrogen peroxide. A dry solid powder composition used in the procedure includes at least one oxidizing agent, an activator to change the PH of the oxidizing agent from acidic to alkaline, a drying agent for absorbing moisture present in the mixture, an accelerator for accelerating the bleaching process, a thickening agent, a humectant and a chelate agent.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
136 words
The method of highlighting the natural color of human hair comprising the steps of a. moistening the hair with water and towel drying it, b. teasing the hair lightly, c. sprinkling a dry powder bleach mixture uniformly onto the hair permitting some of the mixture to sift downward through the hair, said bleach mixture comprising at least one oxidizing agent, an activator to change the pH of the oxidizing agent from acidic to alkaline, a drying agent for absorbing moisture present in the mixture, and a thickening agent, d. applying a mist of a solution of hydrogen peroxide to the hair to contact the mixture, said hydrogen peroxide having a strength in the range of 30 to 50 volume, and e. rinsing and shampooing the hair within five (5) minutes after application of the hydrogen peroxide.
Claim 2
Independent Claim
136 words
The method of highlighting the natural color of human hair comprising the steps of a. moistening the hair with water and towel drying it, b. teasing the hair lightly, c. sprinkling a dry powder bleach mixture uniformly onto the hair permitting some of the mixture to sift downward through the hair, said bleach mixture comprising at least one oxidizing agent, an activator to change the pH of the oxidizing agent from acidic to alkaline, a drying agent for absorbing moisture present in the mixture, and a thickening agent, d. applying a mist of a solution of hydrogen peroxide to the hair to contact the mixture, said hydrogen peroxide having a strength in the range of 30 to 50 volume, and e. rinsing and shampooing the hair within five (5) minutes after application of the hydrogen peroxide.
Claim 3
Dependent Claim
34 words
The method of claim 1 in which a protective cream is applied around the hair line, top of the ears and around the neck line prior to sprinkling of the dry powder bleach mixture.
Claim 4
Dependent Claim
24 words
The method of claim 1 in which care is exercised in the sprinkling step to avoid contact of the bleach mixture with the scalp.
Claim 5
Dependent Claim

The method of claim 1 in which the strength of the solution hydrogen peroxide is color coded.
Claim 6
Dependent Claim
54 words
The method of claim 1 in which the dry powder bleach mixture is a composition comprised of at least one oxidizing agent, an activator to change the PH of the oxidizing agent from acidic to alkaline, a drying agent for absorbing moisture present in the mixture, and an accelerator for accelerating the bleaching process.
Claim 7
Dependent Claim
35 words
The method of highlighting the natural colors of human hair comprising repeating steps c. and d. of claim 1, and rinsing and shampooing the hair within two (2) minutes following the application of hydrogen peroxide.
Claim 8
Dependent Claim

The method of claim 1 in which the bleach mixture also includes a chelating agent.
Claim 9
Dependent Claim
14 words
The method of claim 1 in which the bleach mixture further includes a humectant.
Claim 10
Dependent Claim
