light therapy improves hair count in male pattern baldness

This study (a double blind randomized controlled trial) looked at red light therapy using either 655 nm lasers or 655 nm L.E.D’s and found that both groups had significantly increased their total hair count after the course of the 16 week study. Both groups applied the light every other day for a total of 60 treatments, and both groups benefited by around a 35% increase in hair count <view study>
