An absolute must have for silky hair
So good, I recently bleached my whole head and my hair is the healthiest it's ever been because of this product. I could not recommend it more. I would pay millions for this product.

Worth every penny!!
I need k18 to never stop making this product. This version has 2 less alcohols than the original. It also smells amazing and my hair is shiny for the first time ever!
