What Else You Need To Know

GRO+ Advanced Hair Serum

Formulated for those with severe shedding, this hair serum is powered by our patent-pending GROActive+ Complex™, an innovation that is helping to redefine the results of what a plant-based formula can achieve. The compound features an AI-selected blend of antioxidant-rich Rhapontic Rhubarb Root and Japanese BeautyBerry Extract that work synergistically to help improve hair density. Applied daily to the scalp, the serum also contains Spanish Microalgae, a prebiotic superfood that hydrates to rebalance the scalp environment. Plant stem cells help anchor hair follicles from the root, empowering thinning hair to thrive again.

    Autoimmune hair loss

    I have been using this product for several years in order to combat my autoimmune hypothyroidism, hair loss. At one point, I was losing my hair in large clumps in the shower. I started to use their serums and within a matter of six months of consistent use I started to see a real difference in the thickness of my hairline. I still consistently use the serum to keep my hairline full. I am currently using this serum while pregnant and have not noticed any hair loss yet. I am hopeful that the steer will continue to keep my hair loss at bay postpartum.

    Nice Product

    I have noticed a reduction in hair fall since starting this product and it also doesn't bother my scalp. My scalp is very sensitive. I haven't noticed a huge change in hair growth but I'm starting my third bottle so we will see.

    This product works!

    I’ve been using this product for more than a year and I feel so much more confident. I had a wide part and thinning hair with visible scalp. My part/hair look so healthy and the visible scalp has significantly decreased. My hair also grows very fast. I use it nightly and it does not make my hair greasy at all. I highly recommend this for anyone with thinning hair. It takes months to notice change so be patient with the results.
