Combat hair thinning and restore confidence with our RootMD Hair Thickening Shampoo
RootMD Thickening Shampoo is a hair surgeon-formulated, science-backed shampoo developed by Dr. Ross Kopelman, a board-certified hair surgeon who has treated thousands of patients for hair loss. Unlike conventional shampoos that only cleanse the scalp, RootMD works at the follicle level to address the root causes of hair thinning — including DHT buildup, poor scalp circulation, and oxidative stress.
Formulated with natural DHT blockers including saw palmetto and pumpkin seed oil, along with rosemary oil shown in clinical research to support hair density, this shampoo helps protect follicles while strengthening strands from root to tip. Biotin and panthenol reinforce the hair shaft, while menthol and panax ginseng stimulate scalp circulation to support healthier, more active follicles.
Sulfate-free, paraben-free, and cruelty-free, RootMD Thickening Shampoo is gentle enough for daily use on all hair types. For best results, use 3–5 times per week and pair with the RootMD Thickening Conditioner and Hair Growth Serum as part of the complete four-step system. Made in the USA, 8 fl oz.
Apply a quarter-sized amount to wet hair. Massage into scalp. Leave on for at least 2–3 minutes before rinsing thoroughly. For best results, use daily and pair with RootMD Hair Growth Oil for enhanced benefits.
Key Actives:
A DHT-blocking shampoo is designed to reduce the impact of dihydrotestosterone (DHT) on hair follicles, supporting scalp health and promoting healthier hair growth. RootMD products combine medical expertise with proven natural ingredients to deliver results you can trust.
Scientific studies have evaluated ingredients such as rosemary oil and saw palmetto in reducing hair loss. A randomized trial showed that rosemary oil produced hair regrowth comparable to 2% minoxidil after six months.
Other peer-reviewed studies highlight saw palmetto’s role in blocking DHT activity at the follicular level. These findings support the inclusion of such natural ingredients in RootMD’s formulas.
Dihydrotestosterone DHT is a hormone formed from testosterone. In sensitive hair follicles, it binds to receptors and shortens the hair growth cycle.
This process leads to thinner strands, weaker hair shafts, and, in many cases, male pattern baldness.
People with early signs of thinning, shedding, or a family history of male pattern baldness benefit most.
Men and women experiencing telogen effluvium, postpartum, hormonal, or stress-related hair loss may also see improvement when DHT is reduced at the scalp.
