"Why Does Hair Turn Gray"
Ever wonder why your mom, dad, and grandparents have gray, white, or silver hair? This is just another natural part of aging. Each hair is made up of two parts: a shaft, and a root. The shaft is the colored part that is seen by the human eye. The root is the bottom part, which holds the hair anchored under the scalp. Each root is surrounded by a tube of tissue located under the skin, known as the hair follicle. Hair follicles contain a certain number of pigment cells, which continue to produce a chemical, melanin. Melanin provides each shaft with color whether it be red, brown, blonde, etc.
You are probably familiar with the fact that every human being has a different skin complexion. Melanin is the same chemical that makes skin color fair or dark. As we age, the pigment cells in our hair gradually die, which causes a more transparent color. Eventually ones hair color will completely turn gray due to the the small amount of pigment cells not being able to produce as much melanin.
You may ponder on the fact that younger individuals have gray hair. This is due to one's genes. If your parents started to get gray hair at an early age, most likely you will start around that same age.
