It doesn’t take much Internet searching to debunk this long-held myth. There is tons of information out there decrying this one. Yet, it lives on.
The website www.hair-styles.org theorizes that the myth got its start in the military when young men entering the service were required to wear hats and soon showed signs of thinning hair. But the connection was more likely mere coincidence, since the age the men enter the military is also the same age that male pattern hair loss generally begins.
