Abstract

Abstract A method of restoring the normal moisture level to hair initially having a severe moisture deficiency comprising the steps of: (1) shampooing the hair with a moisture stabilizing shampoo; (2) at least once a week, applying a moisture gain intensive conditioner to freshly shampooed hair; (3) at least once a week, applying a moisture gain deep heat treatment to said freshly shampooed hair; (4) conditioning the shampooed hair with a moisture stabilizing composition when said deep heat treatment or said moisture gain intensive treatment is not used; and (5) thereafter applying a moisture control styling lotion; each of said shampoos, conditioners and lotions comprising from about 0.01 to about 1.0 weight percent of sodium-2-pyrrolidone-5-carboxylate, from about 0.05 to about 5.0 weight percent of glycerin and from about 0.05 to about 5.0 weight percent of glycerin and from about 0.05 to about 5.0 weight percent of protein derived from a collagenous source.
