I can't imagine who reviewed this at Birchbox and thought others would love it. Putting this grease on my hair (NOT my roots) because I shampooed was weird. Why do I want to repelled water when I need to wash my hair? Well, it repelled the shampoo as my hair didn't suds up at all. My hair was terribly greasy the rest of the day. Terrible product. Got to a salon to get better color, do not use this.
