5. The hair color composition according to claim 1 , wherein the at least one carboxylic acid and the at least one amino acid are present in a ratio of about 1:1.
6. The hair color composition according to claim 1 , further comprising at least one fatty alcohol.
7. The hair color composition according to claim 1 , further comprising at least one surfactant.
8. The hair color composition according to claim 1 , further comprising at least one thickening agent.
9. The hair coloring composition according to claim 1 , further comprising at least one solvent chosen from water, glycols, alcohols, or mixtures thereof.
10. A method for altering the color of the hair, comprising applying to the hair a composition comprising:
(a) at least one amino acid comprising taurine,
