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.

An aqueous oxidizing compositions comprising one or more amino acids and hydrogen peroxide are described. The aqueous oxidizing compositions reduce hair damage during chemical services. The effect of hair damage reduction was found to be further improved when polycarboxylic acids were added to bleaching powder, oxidative dyeing, and permanent waving compositions.

A two-part oxidative dyeing composition is described. The two-part composition has an alkaline first part comprising oxidative dye couplers and/or oxidative dye precursors, and a second part comprising hydrogen peroxide, xanthine and/or its derivatives, and a lipophilic compound. The second part is formulated as water-in-oil emulsion and it was unexpectedly found that xanthines stabilize the viscosity of the second part composition allowing for improved dyeing performance.
