I have multiracial hair. It’s mostly curls with some areas that are stick straight. Frizzy. It’s colored. It’s been bleached. I’ve straighten it. And it occasionally is blow dried. In other words, my hair is abused. Now, I do take care of my hair despite the abuse and keep it nice and healthy. As much as I can anyway. This mask made my hair extra smooth and soft to the touch. Much more manageable for a longer period of time. I did leave it on maybe 5 more minutes than the recommended time but I doubt that really had much of a hand in anything.
