Hair Loss (Alopecia)

It's normal for everyone to lose some hair. In fact, we lose about 100 hairs each day as old hairs fall out and are replaced with new ones. With hair loss, though, hair thins at a rate that can't be replaced. When hair falls out and isn't replaced by new hair, a person can become bald or have bald patches. Hair loss can be temporary or permanent, depending on the cause. If changing your hairstyle or other treatment doesn't help, see a doctor. He or she may prescribe a drug to slow or stop hair loss and to help hair grow.
As with the rest of our bodies, hair is healthiest when we eat right, exercise, and protect it from too much sun.
