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.

    GRO+Advanced Hair Serum

    I have been using the GRO+Advanced Hair Serum for about a year now.

    My hair was falling out and as soon as I started using the serum, the fallout stopped.

    I now am seeing new baby hairs in the really thin patches - this product worked for me.
