- A six-month prospective study published in *Dermatology and Therapy* showed Nutrafol's hair growth nutraceuticals increased linear hair growth rate by 19% to 37% in 180 women aged 18–70 (p<0.001). - The study is notable for measuring linear hair growth rate (LHGR), a technically demanding endpoint rarely assessed in clinical hair research, using Canfield HairMetrix imaging technology. - Participants also experienced statistically significant increases in anagen hairs, total hair count, terminal hair count, and scalp coverage, with self-assessments reflecting consistent improvements. - Nutrafol has now completed 26 clinical studies, including three randomized placebo-controlled trials, reinforcing its position as the #1 dermatologist-recommended hair growth supplement brand.
