If you pluck out one gray hair, two or three will sprout in its place.
While this isn't true, plucking out those gray strands is a bad habit. You can damage the roots, causing infection or leaving a scar. Hair has color because cells in our hair follicles called melanocytes create pigment (color) in the hair. When these cells stop producing the pigment, the hair loses its color. Plucking out one gray hair will not affect the melanocytes in the other hair follicles, so other hairs will not turn gray as a result. Gray hair can occur as a result of age or a medical condition.Here are a few more interesting facts: Your "gray" hair is actually transparent, but appears gray due to the dead cells that make up the strand and smokers are four times more likely to have gray hair and premature hair loss.
