I have been getting this treatment done since 2 years now at an interval of roughly six months and it is what keeps my hair sane. I have a wavy structure and I like it toned down a little bit just to smoothen and relax the waves but not a poker straight delusory hair and it does exactly that. However, my major concern has always been frizziness and this treatment works like a magic wand. It doesnot involve any chemical infused products and price range is also decent.
