LOVE K-18 SYSTEM

I’VE BEEN USING THE K-18 HAIR MASK FOR A YEAR AND LOVE HOW IT ONLY TAKES 4 MINUTES FOR MY HAIR TO GO FROM A TANGLED MESS TO EASY TO COMB . BUT I ALWAYS WONDERED ABOUT THE VARIOUS SHAMPOOS THAT I WAS USING. NOW THAT K18 PEPTIDE PREP SHAMPOO IS AVAILABLE, MY HAIR IS MORE SHINY AJND SMOOTH THAN BEFORE. I’M SOI GLAD TO BE ABLE TO USE THE COMBINATION OF 2 PRODUCTS. THANK YOU

K-18 Products

The K-18 product is great.

My hair was damaged from years of highlighting/ color. After using the leave in conditioner and shampooing with maintenance shampoo. Hair is feeling silky and shining.
