Your hair goes through three phases of development: growth, transition, and resting. Each strand has three layers; the outer layer gives the much-required shine, the middle layer has the pigment cells, which add color to your hair, while the third layer is not really visible and is often found missing if the hair is extremely fine. If the pigment cells in your hair become inactive, it turns white.With age, both men and women experience graying and often color their hair with permanent chemical hair dyes. These might be to cover grays, but the harm done is indispensable. A consequence of this action is damage to the hair cuticle that ultimately degrades the hair's structural integrity. Your hair may become dry, brittle, unhealthy-looking over time.
