The present disclosure relates to methods for treating hair, which are particularly useful for repairing, strengthening, and protecting hair from damage. The methods include applying to the hair each of the following components, together, separately, or in any combination thereof, in one or more hair-treatment compositions: (a) at least one amino acid or amino sulfonic acid, and/or a salt thereof, which is present in at least one of the one or more hair-treatment compositions in an amount of at least 0.5 wt. %; (b) at least one non-polymeric mono, di, or tricarboxylic acid, and/or a salt thereof, which is present in at least one of the one or more hair-treatment compositions in an amount of at least 0.5 wt. %; and (c) at least one non-taurate surfactant, which is present in at least one of the one or more hair-treatment compositions.

Hair treated with the methods exhibit desirable cosmetic properties such as smoothness, gloss, improved combability, and improved strength and elasticity.
