I am getting ready to have my hair done with the coppola straightening Keratin treatment, and had one concern. My hair is bleached blonde. It is in amazing condition for bleached hair, but it is still highly processed. I want to do this to help with frizz and curl. I was also hoping it would strengthen the hair with the deposit of the keratin. Has anyone out there done this on bleached hair? I know you are suppose to reduce the flat iron to 430, instead of 450...however, I feel like that is still really hot! I was thinking 380.... Any feedback would be appreciated!
