About nails: More important than you think

Did you know that your nails are made of dead cells, just like your hair? You might pay attention to how your hair looks, but you probably don't give your nails a whole lot of thought. But they're an important part of your body and come in handy. Just think how tough it would be to scratch an annoying itch if you didn't have nails. Or to pick up a penny from the ground. They not only help you do things, but your nails protect your fingers and toes. Also, the look of your nails sometimes can help doctors tell if you are healthy or sick.

A skin doctor (dermatologist) can help you care for your hair and nails, too.
