COMPOSITIONS AND METHODS FOR TREATING KERATINOUS SUBSTRATES USING POLYAMIDES

The disclosure relates to compositions and methods of using the compositions to treat keratinous substrates. The compositions provide a water resistant and non-transferable protective barrier on the substrate. For example, the compositions provide hair with improved shine, condition, manageability and color. The compositions contain at least one polyamide, at least one monoacid, at least one water-insoluble ingredient, solvent and optionally at least one auxiliary ingredient. The methods for treating keratinous substrates involve contacting the keratinous substrates with the compositions of the disclosure.
