My hair has been dyed every color you can think of from hot pink to mermaid turquoise that I am now. My hair goes through a lot of abuse, I bleach it, blow dry it and straighten it. I was looking for something to put that bounce and softness back into it..and I found it! This mask is a lifesaver, it completely took my hair from a poofy frizzy mess to a soft ,bouncy , healthy head of hair. It says to leave in for 3-5 minutes but I sleep with it in overnight due to my hair being damaged to this degree and I've noticed huge results. I definitely recommend this product!
