Rescued my hair

Used after bleaching my hair. Left it much more manageable. A little goes a long way.

This product saved me from being bald headed

After using this product 1 time, it stopped my shedding due to relaxer and medication. After several uses my hair stopped shedding and my stylist was amazed! She purchased some for the salon. I love this product and have told several people who have purchased
