I was so excited when I saw the Ulta Kerastraight treatment. While I was at my salon getting my haircut I had asked her if she had known anything about it. She told me that she went to an all day class and was thoroughly NOT IMPRESSED! It does not reduce frizz, in some cases has made it worse.. causes more damage and can cause it to break off. It is a very harmful chemical that is used. All I have to say is I dont not recommend this treatment for anyone. There are better ways to reduce fizz then chemically killing your hair. The goal is to help it not make it worse!!
