It works!

This shampoo gets rid of product buildup and leaves your hair and scalp really clean. Without damaging your hair. I use it once a week and I feel like my hair is growing longer, faster.

Really cleans your scalp

I love this shampoo. It throughly cleans my scalp and hair of any buildup of products. While at the same time it’s gentle on my hair. I use it once a week.
