Hey. Does plucking grey hair cause more to grow in its place? I'm 20 and I have around 20-25 grey/white hair, heredity and all. So is it a myth or does this actually happen?
The easy answer is no. Of course plucking out one gray hair will not make more gray hairs grow in its place. It won't even make more colored hairs grow in its place. Logic will tell you that if this were true, nobody would be bald or have thinning hair, gray or not. The human scalp has 100,000 to 150,000 hair follicles capable of producing several hairs in a lifetime, but only one at a time. Eighty to 90 percent of these follicles are in an active growth phase at any given time; the other 10 to 20 percent are in a resting phase.
