Now there may be another reason to take saw palmetto: new hair growth.
According to the May/June ’12 Well Being Journal, Colorado researchers gave either saw palmetto or a placebo to 20 men, aged 23 to 64, who had mild hair loss.
Among those who took the supplement, 60 percent showed improved coverage and thickness. The authors concluded, “This pilot study showed significant hair-restoration benefits.”
