Two young sisters in Ghana and a young internal medicine doctor in Kenya have something in common: a white hair streak. The white hair streak is a natural condition called poliosis. Socially it is referred to as the "Mallen streak". According to folklore, people who have it are respected as strong, powerful individuals. But while poliosis itself is not a harmful condition, it is associated with various other medical issues. Some of these are harmful, and some are not. When you notice a white streak in your hair, is it time to see a doctor? The 麻豆社's Dorcas Wangira reports.
