The GROH® Ergo Boost product line leverages powerful antioxidants to promote thicker, stronger hair and lashes, healthier skin, and increased nail strength, as shown in a recent research study.


Our 90-day hair and scalp study included a mix of gender and age, there were no specific hair or scalp conditions associated with study participants. GROH is not just a solution for a problem, but can benefit everyone, helping each person make personal improvements.

Our study included the measurement of physical channels of the hair and scalp, as well as, blood testing to track the effects of Vitamin D changes throughout the study. We tracked Vitamin D including D2, D3, and total. Vitamin D is an essential nutrient to maintain healthy hair growth cycles and minimize shedding.

Each participant took 2 capsules daily of the GROH Daily Replenishing Supplements and used ErgoBoost Hair & Scalp Conditioning treatment 3x a week. Participants completed brief questionnaires every two weeks and submitted blood samples at the beginning and end of the 90-day period. At the end of the study, participants completed a comprehensive exit survey of which, we have shared the results!

HAIR CARE STUDY: Autumn Season

Because this study took place from September to November, we observed that all participants experienced a drop in Vitamin D3 levels, directly related to their limited exposure to sunlight during the Autumn season.


All participants noted an immediate difference in their hair – their hair was softer, shinier, and smoother within 2-4 weeks of use. At the end of the study, 87% of participants said their hair keeps better until the end of the day. Starting at 60-days and through the remaining 90-day study period, participants consistently reported significant improvements in skin appearance, as well as, improvements in nail health as measured by increased nail strength (75% of participants) and faster nail growth (81% of participants).

After 90-days of using the ErgoD2 supplements in combination with the ErgoBoost conditioning treatment, 88% of people reported decreased hair loss (less hair in drain, comb, or pillow), 75% reported faster hair growth, 94% reported increased hair thickness, 92% reported decreased hair breakage, and 94% reported increased hair volume. Similarly, we observed statistically significant increases in hair growth potential, hair strength, hair flexibility, and hair hydration.


Hair thinning affects 25 million women in the US alone. 1 in 4 women suffer from some level of loss or thinning hair. The primary reasons for this hair loss include stress, heredity, illness, and poor nutrition. 


Your stylist knows your hair and can tell when changes are impacting your overall well being. We are thrilled to partner with Salon Visage to bring this revolutionary new innovation to every salon guest.
