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.
