Review: I love everything about this product! Pricey but sooooooo worth it!!!! Used as directed and within the first week I started noticing a difference. My hair is softer, way less breakage, hair looks healthier, helped the hair growth. Smells really good too. I wish I would’ve taken before and after pictures.
