Hair loss can affect just the scalp or the entire body and can be temporary or permanent. It may be the result of heredity, hormonal changes, medical conditions, or a normal part of aging. Anyone can lose head hair, but it is more common in men.
Baldness generally refers to excessive hair loss on the scalp. Hereditary hair loss in old age is the most common cause of baldness. Some people prefer to let hair loss run its course without treatment or concealment. Others may cover it up with hairstyles, makeup, hats, or scarves. And still others choose one of the available treatments to prevent hair loss or restore growth.
