There is a strong belief among some people that a person's hair color can tell you some about their personality.  A new study out of Harvard suggests hair color can also tell you about a person's health risks.

FOX's Colleen Cappon reports in today's "Housecall for Health":

Top doctors say you can tell a lot about a person's health from their hair color:

-Blondes have a higher risk of melanoma, especially on their scalps, and should always wear a hat in direct sunlight.

-Brunettes are more likely to suffer from hair loss, and can help prevent it by getting enough iron.

-And a Harvard study finds redheads may have a 90% greater chance of developing Parkinson's Disease because of a specific gene mutation.
