This was gifted by Vegamour. This is a amazing hair serum! The Vegamour GRO serum has become a new favorite! I noticed in just a short time how many baby hairs have been growing in at a rapid speed. After looking into this product more, I’ve realized that it is clinically studied which makes me trust a product so much more. This stuff is super lightweight and I don’t even feel it on my scalp I rea Elizabeth S. · vegamour.com

This serum has honestly been a game changer for me. My water at home is very harsh and my scalp always feels dry and itchy after I shower. I also feel like I’ve been losing hair lately. My fist bottle I noticed a big difference, definitely waaay less dandruff and my hair feels thicker at the roots. Nothing miraculous, my scalp just feels hydrated and my hair feels more healthy as a result. I stopp bagso · sephora.com
