HOLY GRAIL
Omg if I could give this product 10 stars!!! I recently got a balayage, I’m a natural brunette & of course with any bleaching there will be some damage to your hair. I purchased this to help keep my hair as healthy as I could. Safe to say, my hair has been looking so good! My hair is soft, looks hydrated, and I’ve definitely kept it healthy as much as possible.

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.
