3 RATING IS FOR THE COMPANY not product itself

"The Keratin products are amazing and I love the results. However I hate that they bundle the product together. Would you please let us stylist purchase the product without the shampoos or the accompanying take home treatments,PLEASE!! I'm so frustrated I'm running out of room to store the pre-shampoos. I now have 8- back bar bottles of pre- shampoos from Max to Express. And it will be 3 ordering treatments so now 10 bottles that will be added to Pre shampoo graveyard. I'm running out of room!! On top of the sprays and conditioner support/take home products that you give away for to guest, it's a lot . When you are forced to get all this product when you just wanna purchase the actual solutions. For me I'm not a maximalist and maybe people will be happy to take it, I just don't have anymore room. Please reconsider allowing us just to purchase the Keratin solution by itself. Or have options to purchase packages and or the solution alone."

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"

"This was a great relaxer alternative for my client. The application was straightforward and the results were smooth and shiny hair."

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"

Q&A

Hi, my stylist did a face framing highlights,permanent dye service, and then used the NKST treatment on my curly 3B hair 13 days ago. She did not do more than 2 passes. The hair is still almost just as curly as before the NKST treatment just slightly loose. I wanted looser curls. The salon said their pamphlets don't say how long to wait before repeating a keratin treatment. But they recommend 1 month. How long would you recommend before they can do the KC Max treatment on my hair?
Hi Karla, Our NKST can be reapplied 2 weeks after the initial treatment. As far as technical questions, please contact our Customer Service team at 888-409-4445 or info@keratincomplex.com
Hi, I recently tried the KC Texture on a client of mine with extreme frizz/course/curly hair and didn’t really touch it. The KC max has been the only thing that has helped. I guess my question is if I have l ft over texture treatment and KC max treatment, could they be mixed?
Hi Lauren, Unfortunately, the treatments cannot be mixed together. I will have our Customer Service team reach out to troubleshoot with you on our KCTEXTURE.
Is KCMax applied , dried flat ironed & rinsed @ home by client 3 days later ?
Hi Deanna, Our KCMAX Treatment, once complete should be left in the hair for 24 hours before it is rinsed. It can be left in longer if desired, but leaving it in longer will not add to the longevity. For full instructions on our treatments, you can head to the Resource Center on our Pro site. If you have any questions, please also feel free to contact our customer service at 888-409-4445.
