Don’t hesitate- it’s great.

"Clients are in love!!!"

— Alissa P. (5/5)

Go with NKST instead if you can

"I originally had the NKST and was very excited with the results. It was time to get the treatment done again, however my salon only uses the KC Max now. Just had the treatment done last weekend and washed my hair last night, very disappointed, it offers about 50-70% of the results compared to NKSt. I rather wait 72 hours to wash my hair."

KERATIN MAX

"So far I’m loving it. Smoother process and the silk and shine results are amazing."

— Lilia A. (5/5)

"Keratin Complex has truly elevated the standard for smoothing treatments. As a salon professional, I’ve worked with various keratin brands, but Keratin Complex consistently delivers reliable, healthy, and long-lasting results. It’s especially impressive how well it smooths frizz, restores shine, and improves overall manageability—without compromising the integrity of the hair. Love love love this brand"

Love KCMAX

"Love love the KCMAX, in fact the results are GREAT and way more than I expected. I would definitely make it a main service in my salon. The only problem I had that it didn’t arrive the time I wanted even though I paid for the fast delivery. Anyway, the results were amazing. Love it"
