Smooth but brassy hair

"My hair feels amazing smooth but this treatment in particular stripped my color. I have never had an issue with the KCMAX or the Express. Will definitely not buy this for my salon again. Thank goodness I tried it on myself before using on my clients."

— Shelly K. (3/5)

Q&A

Can you do a color service right after smoothing treatment?
Hi Danette, Any highlighting should be performed prior the the KCSMOOTH Treatment. Once the treatment complete you can apply color/toning services after the Restorative Leave In Lotion is applied. For further information please feel free to contact our Customer Service Team at 888-409-4445 or info@keratincomplex.com
