experiments have shown that saw palmetto has a positive effect on benign
prostatic hyperplasia, but a group of scientists decided to take it one step
further and decided to test the effect of oral intake of saw palmetto on male
pattern baldness in a pilot study involving men between the ages of 23 and 64.
The dose used was 400 mg per day, the equivalent to about 4 g of berry. The
double-blind results showed that 60% of the volunteers receiving active
treatment noticed improvement, compared to only 11% for the placebo control
group.
It is also possible that topical
application may also be effective since it delivers a higher concentration of
dose to the affected area. A daily application at night could substantially
improve the results of the clinical trial.
