Abstract: Cosmetic compositions, kits thereof, and methods of making and using such cosmetic compositions. The cosmetic compositions typically include about 20 to about 95 wt. % of a polyol; about 5 to about 70 wt. % of one or more monoalcohols having from 2 to 6 carbon atoms; about 0.1 to about 10 wt. % of one or more cationic surfactants; about 0.1 to about 20 wt. % of one or more fatty compounds; and about 1 to about 15 wt. % of a combination of a urea compound and citric acid, wherein all weight percentages are based on the total weight of the cosmetic composition. The cosmetic compositions have a weight ratio of polyol to monoalcohol(s) that is from 20:1 to 1:20. Additionally, the cosmetic compositions typically have a mole ratio of citric acid to urea compound of that is about 10:0.5 to about 0.5:10.

Abstract: The present disclosure is drawn to methods for oxidatively bleaching or coloring hair. The methods employ a fortifying composition and a conditioning composition, which are used in various routines. Treating hair according to the routines prevent, minimize, or mitigate damage to the hair caused by the oxidative bleaching or coloring process. The fortifying composition includes: (a) citric acid, a salt thereof, or a combination thereof; (b) cyclodextrin, a salt thereof, or a combination thereof; (c) one or more polyols; and (d) water. The conditioning composition includes: (a) one or more cationic surfactants; (b) one or more non-silicone fatty compounds; (c) one or more silicone oils; and (d) and water. The methods strengthen the hair, improve curl retention of the hair, prevent frizz of the hair, and remediate damage to the hair caused by chemical bleaching or coloring of the hair.
