Hair loss (alopecia) can affect just your scalp or your entire body, and it can be temporary or permanent. It can be the result of heredity, hormonal changes, medical conditions or a normal part of aging. Anyone can lose hair on their head, but it's more common in men.
Baldness typically refers to excessive hair loss from your scalp. Hereditary hair loss with age is the most common cause of baldness. Some people prefer to let their hair loss run its course untreated and unhidden. Others may cover it up with hairstyles, makeup, hats or scarves. And still others choose one of the treatments available to prevent further hair loss or restore growth.
Before pursuing hair loss treatment, talk with your doctor about the cause of your hair loss and treatment options.
Hair loss can appear in many different ways, depending on what's causing it. It can come on suddenly or gradually and affect just your scalp or your whole body.
Signs and symptoms of hair loss may include:
See your doctor if you are distressed by persistent hair loss in you or your child and want to pursue treatment. For women who are experiencing a receding hairline (frontal fibrosing alopecia), talk with your doctor about early treatment to avoid significant permanent baldness.
Also talk to your doctor if you notice sudden or patchy hair loss or more than usual hair loss when combing or washing your or your child's hair. Sudden hair loss can signal an underlying medical condition that requires treatment.
Male-pattern baldness typically appears first at the hairline or top of the head. It can progress to partial or complete baldness.
Female-pattern baldness typically starts with scalp hairs becoming progressively less dense. Many women first experience hair thinning and hair loss where they part their hair and on the top-central portion of the head.
Hair loss can occur if you wear pigtails, braids or cornrows, or use tight hair rollers. This is called traction alopecia.
