Stress Proven to Cause Gray Hair?

Posted Jun 16 2009 11:35pm

Mid Brain muses…

Scientists think they’ve figured out the cause of gray hair. In the June 12 issue gray hair of Cell, researchers describe ‘genotoxic stress’ that damages DNA and reduces the amount of melanin-producing cells (melanocytes) in hair follicles.

What kind of stress?

While emotional stress may be one factor, the kind of stress that these researchers are talking about are more molecular in nature. These include exposure to UV light, ionizing radiation and mutagenic chemicals. It’s estimated that cells get exposed to over 100,000 stressors each day.

Can you stop gray hair?

According to researchers, the cell damage is unavoidable which suggests there is little that can be done to stop the gradual onset of gray hair. Sun protection and anti-oxidants may help slow things down but eventually exposure to environmental stress will catch up to everyone. Fortunately, cosmetic chemists have come up with hair color.  So everyone can look like they’ve got the hair of a 20-year-old.

When did you start to go gray?  And do you cover it up with hair color?  Leave a comment below because inquiring Beauty Brains need to know.
