Why scientists want to get to the root of grey hair
Early, late or not at all ... scientists are exploring the many mysteries of grey, white or silver-looking hair to learn more about ageing and also to understand what hastens greying,
Researchers are looking to see if there are links between greying hair and health.
Marco Kaltofen was 11 when he noticed his first white hairs. As his hair grew whiter, his middle-school friends started calling him "the professor." By his mid-30s, it was completely white, as it had been for three of his grandparents. His parents went white in their 40s. "So I had no chance of avoiding this," Kaltofen says.
Now 61, he is a civil engineer. He wears his white hair in a ponytail. "White hair is part of my identity, and I am completely at peace with it," he says.
