Rated 5 out of 5 by from Smooth blonde hair that stays blonde with no frizz I’ve been using Keratin Complex since it came out, but it did always darken the blondes until this wonderful product came out!! We get the best of both worlds with smooth non-frizzy hair and blondes stay blonde for months!!

Rated 5 out of 5 by from Love it! I used this keratin complex blonde on slightly damaged dark hair (which it says not just for blondes). and the results were WAY better than all the other keratin complex treatments I was use to doing. Hair is very silky smooth and alot easier and quicker to dry. Even after washing. The drying time was cut in half maybe more. I would definitely use this again.

Rated 5 out of 5 by from nice treatment I’ve used the NKSTB treatment on myself twice. I’ve got fine highlighted hair and my goal has been to grow my hair out. This treatment i feel helps my ends from getting to fragile allowing me to actually see the length I’m getting. Love the treatment, my hair feels so fortified and smooth after it’s freshly done.
