Abstract: The instant case relates to a method or routine comprising: (i) treating hair with an alkaline composition; (ii) treating hair with a conditioning composition; (iii) applying a leave on composition to the hair; and (iv) subjecting the hair to a thermal heat treatment. The alkaline composition comprises one or more alkalizing agents, such as an alkanolamine, and water. The conditioning composition comprises: (a) citric acid, a salt thereof, or a combination thereof; (b) cyclodextrin, a derivative thereof, or a combination thereof; (c) one or more cationic surfactants; and water. The leave on composition comprises: (a) one or more silicones; (b) one or more film-forming polymers; and (c) water. The hair is subjected to a thermal heat treatment, for example, treatment with a hot iron at a temperature of 150 to about 280° C. The methods improve hair fiber alignment, reduce frizz, and provide smoothness to hair.

Abstract: Hair treatment compositions and methods of using them to treat hair are described. The hair treatment compositions include: (a) citric acid, one or more salts of citric acid, or a combination thereof; or a combination of citric acid and one or more salts of citric acid, wherein the weight ratio of citric acid to salts of citric acid added to form the combination is from 1:10 to 10:1; (b) one or more surfactants; and (c) water; wherein the pH of the composition is from about 3 to about 10; and weight percentages are based on the total weight of the composition. The hair treatment compositions are particularly useful for strengthening hair fibers.
