I don’t like the smell of these products at all, but hot damn, they work! I used to dye the living baloney out of my hair, but I’ve since stopped and because of all the damage I caused to it, I’ve had to use repairing hair products. This mask was one of the weekly masks I used. It really does repair hair and makes it shiny and manageable. The only problem for me is the smell, and the fact that you can’t leave this mask on for longer than a minute, because it makes your hair hard and brittle then. I’m assuming because of the keratin in the mask.
