What if some gray hair is not simply a sign of age, but a receipt for stress?
Contrary to popular belief, graying hair is not necessarily a permanent sign of aging; it is often a sign of a hair follicle struggling with energy resistance. Interestingly, white hairs actually contain more mitochondria than colored hairs because the follicle cells overproduce them in a desperate attempt to stay alive. This struggle wastes a massive amount of energy until the follicle passes a threshold and loses its pigmentation.
