How to use this product

Key Ingredients

Tap into the power of plant active ingredients.




Curcumin Stem Cell Extract
Curcumin Stem Cell Extract

Also commonly known as turmeric, it has been shown in clinical studies to help prevent causes of hair loss by inhibiting DHT production and supporting IGF-1 & BMP4 production.

Red Clover
Red Clover

Rich in isoflavones, red clover may act as a natural DHT blocker to help minimize issues such as hair thinning and hair loss.

Mung Bean
Mung Bean

Mung bean contains copper, an essential element for scalp and hair health, and may strengthen the ability of the hair follicle to resist premature shedding.

Just the facts

Frequently Asked Questions

Results vary by individual. Used as directed, you can expect to see thicker, fuller looking hair by month three, with the maximum appearance of increased hair density by month four.

Like all living things, hair has a growth and rest cycle. Many factors like age and stress-levels can impact your growth cycle. We recommend daily use of our GRO Hair Serum. Many see results as soon as 90 days, with peak results appearing after as few as 4 months of daily use.

    Noticeable Difference

    My scalp feels healthier! I can definitely skip a day of washing (when I don’t get sweaty at the gym). My hairstylist also said she noticed baby hairs growing! I’m three months in and I love this product. I’ll give an update at 6 months.
