Hair care compositions and methods for improving curl retention of hair are provided. The hair car composition may include a carrier and a quaternary ammonium compound. The method for improving curl retention may include contacting the hair care composition with surfaces of the hair of a subject in need thereof.

The present disclosure relates to hair care systems comprising: (1) a booster composition containing at least one ionic polymer functionalized with at least one carboxylic acid moiety; optionally, at least one compound selected from an alkoxysilane, a nonionic latex polymer, or mixtures thereof; a thickening agent; and a cosmetically acceptable carrier; and (2) a hair treatment composition containing at least one surfactant selected from an anionic surfactant, an amphoteric surfactant, a cationic surfactant, a nonionic surfactant, or mixtures thereof. The hair care systems of the present disclosure can be used to clean and/or condition hair, as well impart frizz control and manageability benefits to hair.

An aerosol cosmetic composition is provided that includes an oil soluble gloss enhancing film forming component, a solvent, a colorant, a propellant, and useful for application to hair or skin. An aerosol dispensing system and a method of preparing an aerosol sprayable color composition are also provided.

Compositions are provided that include date palm pollen or an extract thereof. The compositions may be formulated for topical use in methods of treatment or prophylaxis of various skin conditions or methods to counteract the effects of skin aging.
