My salon just started using Coppola and I am considering having this process done.
My stylist said that there is a big difference in the safety (both to the hair and to one's health) between the Coppola and other brands of BKT.
I know that the active ingredient in Coppola is "adehyde" and that "formaldehyde" is in many of the other BkT's. Is there a significant difference between the two?
I would really appreciate any feedback, either from stylists, or from clients who have had both Coppola and a formol-based BKT done.
