The instant disclosure relates to methods and kits for artificially coloring hair and improving the durability of the artificially colored hair. The methods include: (I) combining an antioxidant booster composition, a hair coloring base composition, and a developer composition to form an antioxidant-enriched hair coloring composition within 2 hours of application to the hair; (II) applying the antioxidant enriched hair coloring composition to the hair and allowing the antioxidant enriched hair coloring composition to remain on the hair for a period of time; and (III) rinsing the antioxidant enriched hair coloring composition from the hair. The antioxidant booster composition can be included in a kit with a hair coloring base composition and/or a developer composition, wherein the antioxidant booster composition, the coloring base composition, and the developer composition are separately contained.

PLGA-based polymers include pendant nucleophiles protected with photocleavable protecting groups. Upon deprotection, the polymers degrade rapidly via intramolecular cyclization into small molecules. The polymer may be formulated as a nanoparticle, with an encapsulated payload, which may be an imaging agent, a bioactive agent or a pharmaceutical agent.
