Is there a difference between the Coppola and the Foramaldehyde-Based BKT formulas (such as Marcia, Rejuvenol and Global). I know that Coppola uses "aldehyde". Is that the same as "Formaldehyde"?
Is Coppola less damaging to the hair and/or health?
Will it produce a better or worse result (in terms of getting rid of frizz)?
i would appreciate feedback from stylists and from clients who have had both the Coppola and one of the other brands done.
Thanks so much!
