    This changed my life

    I love this product! I switched up my hair routine lastly because I felt my hair was falling out due to my house having hard water, and I had enough. After asking some friends and doing research, I found I was missing steps in my routine. I got this product for my thinning hair along my hairline, and omg after just a month, I find my hair has been coming back. TMI, I had bad acne on my scalp too, and this cleared it. The price is high, but I’m just not ready to give up on my hair. The bottle does go a long way, and the smell is just addicting.

    Unfortunately this product didn’t increase my hair growth. Which is why I am giving it a low rating. It was light weight and was not greasy hence the 2 stars.
