Meet Dr. Hausman
Dr. Marvin S. Hausman, MD, is an Immunologist and Board-Certified Urological Surgeon with over 30 years’ experience in both pharmaceutical and nutraceutical research and development.
The basic nutrients that feed hair follicles must come from within to allow cells to function. The highest concentration of the ergothioneine transporter is found in the stem cell of the hair follicle.
Hair follicles live within the skin and not on its surface. ErgoD2® contained in the GROH® supplements and in all GROH® beauty products, supplies the key nutrients for stem cell survival and hair growth.
Younger, Youthful Skin
The middle layer of the skin (stratum spongiosum), is a primary location of the ergothioneine transporter and improves the elasticity and hydration of your skin.
Vitamin D & Female Hair Loss
30% of women suffer from hair loss. Vitamin D helps play an important role in stopping this occurrence. Our proprietary enhancement purification technology increases the vitamin D levels nearly 1,000 times the amount found in nature.
