Men, two ways to reduce your chances of premature greying

A cross-sectional study of more than 6000 men published in the Journal of the American Academy of Dermatology journal identified three risk-factors associated with premature hair greying:

1. Family history of premature greying (especially on father's side)
2. Obesity
3. Smoking (more than a 5 packet-year history)

You can't change your family, but quitting smoking, and maintaining a healthy body weight can reduce the chance of turning grey early. Do it in 2016.
