Stress. Cigarettes. Junk food. Bad karma. None is responsible for premature graying. For that you can blame Mom or Dad.
Hair turns gray because the pigment cells stop making pigment, or color. Melanocytes are cells responsible for skin and hair color and are found everywhere in your skin and in the base of each hair follicle. In everyone, these hair-based melanocytes eventually peter out. For most people this begins around the age of thirty-five. By age 50, 50% of people are 50% gray.
Some people go gray sooner. If you’re gray before 20 years old, it’s called “premature graying.” This is almost always hereditary. If you’re prematurely gray, talk with your doctor if you have any questions or concerns.
