ABSTRACT:
A method of obtaining a hair damage rating is obtained by determining the change in hair structure, such as measuring the amount of free sulfhydryl groups after hair treatment or exposure to agents, comparing this with a number of such groups before treatment to obtain a percentage change, establishing a rating scale having a range of percentage change values, and selecting the hair damage factor a number corresponding to the determined percentage change after treatment.
