I’m a believer

Ok so I was skeptical . I’ve dyed my hair all my life and so it’s not in the best shape but I do use masks and treatments and try to take care of it. I tried this ONCE using a modified version of the Abby method and my daughter even commented on how soft and healthy my hair looked. I’m loooking forward to continued use to see the benefits. I will say my ends do feel a bit like straw but I hear this means it’s working. My hair is bouncy soft and shiny.

Too little amount of product

For the amount of product and price it is not worth it in my opinion. My hair is not dyed or bleach and I didn't notice a difference. I won't buy again.
