A study evaluating the hair growth effect of a topical saw palmetto serum applied for four weeks and a lotion applied for 24 weeks, in 50 men with androgenetic alopecia.
The researchers found the saw palmetto formulation demonstrated increased terminal hair counts at 12 and 24 weeks.
Terminal hairs are thick, strong, pigmented hairs that have fully matured.
