Did you know thinning hair can be a result of dormant follicles and not actual hair loss?
Groh® is the only hair supplementation formula that gets to the root of a key hair loss problem - awakening dormant hair follicles. In many cases dormant follicles, which can become inactive due to improper nutrition, create the illusion of lackluster hair or permanent hair loss. In reality, these follicles just need the correct nutrients to spur new hair growth.
The #1 salon recommended solution for thinning hair.
Groh® is powered by Ergothioneine, an incredibly powerful antioxidant found in select mushrooms discovered in the forests of the Pacific Northwest. Your body uses naturally occurring Ergothioneine to do one thing only - grow hair, skin and nails. This is why salons nationwide recommend Groh® for new hair regrowth in men and women.
