I've met a few people who have had it done and it looked good, I've always been happy with my curls but I'm bored and looking for a different style (that doesn't take much effort) I suit waves - not straight hair. I was thinking of buying the product online as my BF is a hairdresser, trouble is now I've looked online and read up on the dangers of the formaldehyde, so I'm looking to hear any views, please
