Thicker, Fuller Hair

The #1 Salon Recommended Hair Growth Solution

Did you know thinning hair can be a result of dormant follicles and not permanent hair loss?


Groh® is the only hair supplementation formula for both men and women 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 permanent hair loss. In reality, these follicles just need the correct nutrients to spur new hair growth. 

The #1 salon recommended solution for new hair growth.


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.

What Groh® Customers Say

With my hair growing, I feel so much better about myself. It's not just an outer thing, it's inner beauty too. 

I have been using Groh products for about a year and I love them!  I was experiencing some hair loss and was really worried.  What a huge improvement!  Not only did my hair get fuller but the texture changed.  The texture feels so good and fuller.  

It's important for me to have healthy, shiny hair. And with Groh, that's what I have now. 

It was a drag going outside or to the beach and basically seeing thinning hair. But now both my forehead area and brows have filled in with Groh.
