There’s now definitive proof that hair greying is reversible, albeit rare, in humans. What’s more, stressful life events play a primary role in triggering your hair to turn grey, while relaxation—like a two-week vacation—may help give your roots back their original color.
Grey hair is one of the earliest and most obvious signs of aging. By the time most people reach their 30s, hair begins to go grey, becoming progressively [more] grey with time. It’s generally assumed that once a hair goes grey, there’s no going back, but a team from Columbia University in New York and colleagues suggest this may not be the case.
