It works!

My usual tough, thick hair has finally started to succumb to the bleaching and tight styles I’ve been doing the past year and nothing I’ve been doing on my own is quite got me back to how I like it. One use and my hair is butter soft and way less frizzy. I did use in combo with the shampoo and conditioned after letting the K18 do its thing. Went to bed and woke up to much healthier hair. Just wish the bottle was bigger!

Not much difference

My hair didn’t see much difference besides a bit less of frizz. My hair didn’t have glowing silky soft hair that it showed as results for many.
