Graying hair can be stressful for anyone, but even more so for young people, who are sensitive to even small signs of aging. But scientists say the color change is a natural part of pigment cells' aging that can occur relatively early in life.
The emergence of gray hair is largely governed by genetics, and premature graying tends to run in families. Stress and poor nutrition may also be to blame.
Many people pluck gray hairs, but experts advise against it and say that cutting is less likely to cause damage to follicles.
Some 25-35 follicles come out of a pore on the scalp in a lifetime, and a follicle lives for two to three years. Thus if a hair is plucked out, it cuts pore productivity by up to three years, quickening sparse follicle growth or baldness. This means plucking gray hairs can lead to hair loss.
