Hair Regrowth with Novel Hemp Extract

Dr. Gregory L. Smith, MD, Gregory L. Smith, Inc.

A study was done of 31 subjects (15 males and 16 females) with androgenetic alopecia (AGA). They used a once-daily topical hemp extract formulation, averaging about 30 mg per day for 6 months. A hair count of the greatest area of alopecia was carried out before treatment was started and again after 6 months of treatment. On average, growth was 164% more than baseline, ranging from 31% to 2000% (P value (P<0.00001)) increase in nonvellus hair after six months of once-daily use. This case study suggests that topical hemp extract high in THCV, CBDV and CBD is associated with significant hair regrowth benefits in both men and women with AGA. This was a follow-up study to another study on the effects of CBD for hair regrowth, which had promising results, but with the addition of Varins to the topical formulation, subjects saw twice the amount of regrowth than with CBD alone.
