My hair is frizzy and extremely unruly, and in order to avoid straightening it every day, I have done Brazilian Keratin treatment. My hairdresser had given me a different mask (by the way, after the Brazilian Keratin treatment, you have to wash your hair with specific shampoos and use specific masks). When it ran out, I searched and found this specific mask myself and decided to try it. I really noticed a difference. My hair became smoother and softer. When the shampoo that my hairdresser gave me runs out, I will buy the corresponding one from Braziker.
