Methods for Treating Relaxed Hair

摘要

Methods and kits for treating hair or preventing damage in the relaxing of hair are disclosed herein. Hair that is damaged during a relaxing treatment with hydroxide-containing relaxing agents, can be treated with formulations containing one or more active agents. The active agent formulations can be applied simultaneously with the hair relaxing formulation, or optionally applied immediately following application of the relaxing formulation, to reduce damage and breakage. Use of the active agent formulation along with a relaxing treatment can be used to control the level of curl achieved or retained in the relaxed hair, as compared to the natural amount of curl in the untreated hair.

1. A method for achieving a desired level of curl in hair comprising:
(a) applying to the hair one or more relaxing agents; and (b) applying to the hair an active agent of Formula I: wherein A, B, C, and D are reactive moieties containing one or more charges, and wherein each of A, B, C, and D independently contains a moiety selected from the group consisting of a vinyl sulfone, an acrylate group, a methacrylate group, a styrene group, an acryl amide group, a methacryl amide group, a maleate group, a fumarate group, and an itaconate group; R is a linker that contains two or more charges, wherein the charges are opposite to the charges on the reactive moieties, wherein n=1-10, and wherein R is not a polymer, and wherein the sum of the charges is zero; and wherein the reactive moieties are ionically bound to the linker;wherein each occurrence of p, q, r, and s is independently an integer from 0 to 25, wherein the sum of p+q+r+s is equal to or greater than 2; and
wherein the amount of the active agent is effective to retain a level of curl (percent curl retention) in the treated hair in the range of about 0-99%, compared to the amount of curl in the hair prior to step (a).
