Notice anything different about President Obama's hair over the years?
It happened to Bill Clinton, George W. Bush and Jimmy Carter, and now it's happening to President Obama.
What did all these men have in common, besides holding the highest office in the U.S.?
All of them quickly turned gray during their presidency. Why? One word - stress.
There's a condition called Telogen Effluvium, and in a nut shell Telogen Effluvium is when we're losing our hair more rapidly than we should.
As the stress triggers this condition, it causes the hair to fall out, and every time a follicle loses a hair, and the hair grows back, it uses up pigment.
When each new hair follicle is replaced, pigment is used.
Once the pigment runs out, then gray or white hairs appear.
Now as President Obama enters his second term, it's hard not to notice the fast-spreading speckles of white in his dark hair.
With the economy, gun control and overseas conflicts on his plate, he may see more speckles to come.
