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.

Applied daily to the scalp, the serum also contains Spanish Microalgae, a prebiotic superfood that hydrates to rebalance the scalp environment.

    Worked so so for me

    I have been using Gro+ for over 4 months and results have been under expectations. I use consistently every time I have my hair washed every 2 days. I see more thickness and hair volume but not no hair growth not less grays.

    It works!

    Menopause hit me hard! I was losing my hair, and it had stopped growing. In combination with vitamins, this serum turned it around. My hair is longer and healthier than it has been in years.
