we went to a demo last monday night on the Keune smoothing treatment ( the permanent kind ) Its a combination of the Japanese straightening and the keratin complex kind. Quite a few steps and a lot of very strict rules which kinda freaked me out, made me feel quit stressed about performing the service or worse letting an employee perform the service on a client.
The effect is very good and lasting but it is the kind of straightening that breaks the bonds in the hair like perming so if timed wrong, damage can happen.
