    Perfect for thinning hairline!

    This hair growth serum works wonders for my thinning hair and bald patches! Unlike some others I tried, the serum doesn’t make my scalp feel weighed down or oily at all. This was complimentary from vegamour.

    Be patient and results will follow!

    I’m seriously so impressed with the GRO Jumbo Hair Serum! It’s lightweight, non-greasy, and easy to use daily. I’ve noticed way less shedding and my hair feels healthier overall. I love that it has clean ingredients too. Definitely recommend! Gifted by Vegamour.

    Dense is good

    Gifted by vegamour This hair growth serum made a huge difference in the density of my hair. I noticed it mostly around my temple area even though I used it all over my head. I noticed the difference after about four weeks of use on my scalp. I would definitely recommend this product if you want thicker hair with some hair growth.

    So good!

    I love that this formula isn’t greasy at all. It’s water based so it doesn’t make my hair look dirty. The jumbo size is a life saver, I feel like I go through the smaller bottles so fast. My baby hairs are finally growing back! Gifted by vegamour
