Can Gray Hair Be Reversed?

It's long been a fact of life that if we are lucky enough to grow old, our hair will either turn gray or fall out. Or both. In recent years, the stigma of having gray hair is not as dire as it used to be, and gray hair has become kind of chic among young people. This shift ironically coincides with new research that shows why hair turns gray, and how we can stop it from doing so. Further medical research shows that hair that has already turned gray can, in some cases, start to grow in color again.

Fortunately, most people already know a shortcut to covering gray hair, or changing one's hair color completely. It comes in a bottle and you can even do it at home, as I have off and on since I was a teenager. Now that my hair is partially white, I have expanded my palette to include a range of shockingly unnatural hues. But I can see the value in this research, as it contributes to our understanding of how our bodies work at the cellular level. (via Geeks Are Sexy)
