Our most common questions we receive: 

My hair is thinning, which Groh® product should I use for the quickest results?
A. Begin with our Jump Start Kit, or the Daily Vitality Boost. The key to quick results is the Daily Vitality Boost, which contains the proper amounts of Ergothioneine for optimal follicle health and growth. 

How does Groh® work to grow hair?
A. Decades of research shows that the human body contains a transporter system that essentially carries one nutrient - Ergothioneine - to only one place - our hair follicles. And one of the highest concentrations of the Ergothioneine transporter is found in the stem cells of hair follicles from which hair cells are produced. Groh®'s unique formulas, powered by ErgoD2®, supply nutrients important in stem cell function, and promote restoration of normal hair growth.

The active ingredient within GROH® is ErgoD2®. This potent antioxidant has its own unique specific transporter system within the human body. This transporter is present in the outer cell wall membrane of human cells and is highly expressed in healthy skin, hair, scalp, nails, and lashes.

GROH® products work internally and externally with the body’s complex biological system to help support healthy skin, scalp, hair, nails, and lashes—from head to toe.

Is Groh® Daily Vitality Boost a product natural? 
A. Yes, our Daily Vitality Boost is a whole-food supplement containing a blend of six specialty mushrooms with known and proven health benefits. In addition, our Daily Vitality Boost is 100% vegan and contains no animal products.

What are the active key ingredients in Groh®?  
A. Ergothioneine is a mushroom extract found in very select species of mushrooms. In addition, Vitamin D2 helps to amplify the nutrients found in Ergothioneine and Groh to provide the maximum benefit in a small amount. 

How long before I see results? 
A. Most Groh® customers see new hair growth in 3 - 4 weeks, with noticeable hair growth in 6 - 8 weeks.  

Where can I get more details on each product? 
A. Go to each individual product page, then click each tab under the product description to see detailed benefits and recommended usage. 

Are Groh® products cruelty free?
A. Yes. We do not test our products on animals.
