Studies show saw palmetto supplements may help with hair thinning: users saw 60% improvement in overall hair quality, 27% more total hair count, and increased density in 83% of people. About half stabilized their hair loss. Results came from small studies mixing topical and oral doses (100-320 mg), and it was generally well-tolerated with no serious side effects reported.

Researchers reviewed 5 randomized controlled trials and 2 smaller prospective studies on saw palmetto for hair loss. They searched medical databases for published evidence on safety and effectiveness in people with androgenetic alopecia (male/female pattern baldness) and other hair loss types.
