A study published in the Journal of Alternative and Complementary Medicine in 2002 investigated the efficacy of Saw Palmetto for hair growth in men with androgenetic alopecia (male pattern baldness). The study found that Saw Palmetto was effective in improving hair growth in men, with 60% of participants reporting an improvement in hair density.

  2. A 2014 study published in the International Journal of Immunopathology and Pharmacology examined the effects of Saw Palmetto on hair growth in women with androgenetic alopecia. The study found that Saw Palmetto was able to improve hair density and thickness in women, with no reported adverse effects.

  3. Another study published in the Journal of Cutaneous and Aesthetic Surgery in 2014 investigated the use of a topical Saw Palmetto formulation for the treatment of androgenetic alopecia in men. The study found that the topical Saw Palmetto formulation was effective in improving hair growth in men with androgenetic alopecia.

  4. A review of multiple studies on Saw Palmetto and hair growth published in the Journal of Clinical and Aesthetic Dermatology in 2017 concluded that Saw Palmetto may be a useful natural alternative for the treatment of androgenetic alopecia in both men and women.

Overall, the available scientific evidence suggests that Saw Palmetto may be an effective natural treatment for hair loss in both men and women with androgenetic alopecia. However, more research is needed to fully understand its mechanism of action and potential side effects.
