 Hair

    When you study your image in the mirror, what do you notice first? If you answered "my hair," you're in the majority. Your hair and nails are composed of keratin, a type of protein. The hair roots are beneath the skin in small pockets called follicles. As new hair cells form in the follicles, old ones are forced outward through the surface of the skin.

    In other words, the hair that's visible on the skin's surface of dead cells. The hair on your head grows about a half-inch every month. When a hair ceases to grow, it falls out and is replaced by a new hair.

    Taking care of your hair is important. Use a gentle shampoo, and make sure you rinse it out thoroughly. Try to let your hair dry naturally because blow-dryers and curling irons can be damaging. Research shows that what you put in your body, rather than the expensive products you put on your hair, counts the most. Eating a nutritionally balanced diet is the surest way to have healthy, shiny hair.
