Groh® Hair Growth Boost Duo

Groh® Hair Growth Boost Duo




A powerful duo to quickly boost your overall hair health, stimulate hair growth and improve overall scalp conditioning. With our Boost Duo you save 20% compared to purchasing them separately! 

One of our most popular selections, the Boost Duo includes our flagship Daily Hair Boost supplement formula and our Stimulating Scalp and Thickening Serum. 

Groh's Daily Hair Boost supplement is the secret to Groh's effectiveness. This powerful advanced formula provides the required daily nutritional support for efficient cellular function, which is required for growing new hair, as well as thicker hair, improved hairlines and a healthier scalp.

The secret is our bio-nutrient dense formula, featuring our key antioxidant ingredient, Ergothioneine. By combining Ergothioneine with Vitamin D2 and additional proprietary bio-nutrients, this formula replenishes your body’s essential building blocks to stimulate new hair growth.

Our Groh® Scalp and Hair Thickening serum delivers the active ingredients needed to help promote healthy hair growth, re-balance dry and oily surfaces, soothe dryness and reduce itchiness and flakiness for increased hair growth.  

This oil-free serum, created with the natural antioxidant Ergothioneine, whose unique transporter delivers this bio nutrient directly to skin cells, supports hair follicle health, important for stronger and more vibrant hair.

  • All GROH® products are color-safe and free of parabens, sulfates, petrochemicals, GMOs, animal testing, petroleum and artificial colors.

Use GROH® Boost Duo along with GROH® Restorative Shampoo and GROH® Replenishing Conditioner for best results.

I’m seeing my hair is thicker in texture and appears filled out I’m liking the results for a 74 year young male

Good stuff

I liked very much my experience with the products and did notice a change in thickness in my hair. When I can, I will continue to purchase again. It would be great if the company offered monthly low payments on their products for individuals that have employment but are on a budget to be able purchase the products and pay low monthly payments on an installment payment plan.
