Amazing results
Started using Proaddiction about 6 years ago , I love how shiny and healthy the hair continues to be even months after it’s done unlike keratin treatments that fade and dry up the hair

Not what I expected
I expected this product to stand out in comparison to all the others I have worked with. Using it for the first time, according to your instructions to the tee I expect a better outcome. The hair is still frizzy and not as smooth as I expected to be. The ends are pin straight but that's about it. Every expensive and still have frizzy hair.
