I wouldn't suggesr this brand in particular, but I'm trained in coppola keratin complex and based on that, i can give you a little idea. first, true keratin treatments are something you should never try at home, but def see a stylist. keratin treatments remove frizz and can help relax curl. they strengthen hair, and help give shine. reduce styling time. you can use them on chemically altered and color treated hair to improve hairs integrity. most last roughly 5 months.
