KidsHealth.org notes that 50 to 100 hairs are normally lost every day through washing and hair care. Usually, when a hair falls out, a new hair begins to grow in its place. However, some medical conditions can prevent hairs from regrowing, resulting in hair loss. Although this can be particularly frightening when it occurs to young children, understanding the causes can help you locate the proper treatment.
Tinea Capitis
According to the American Hair Loss Association, the most common cause of child hair loss is the disease tinea capitis, or ringworm, on the scalp. This condition, which is the result of a fungal infection, can cause patchy hair loss on the scalp, eyelashes and eyebrows. Some hairs may also break off at the surface, resulting in tiny block dots on the skin. This condition is usually treated with a shampoo or antifungal medication. If a child uses the medication as directed, he should be allowed to continue school as normal and should not be contagious.
Trichotillomania
MayoClinic.com explains that trichotillomania is a disorder in which a child uncontrollably pulls out hair. She may pull it out from anywhere on the body, including the scalp, eyelashes, arms and eyebrows. This usually results in patchy bald spots that are difficult to hide. Other symptoms include chewing on the hair and playing with yanked out hair. While some children may pull hair unintentionally, others do it deliberately. Treatment usually involves a form of therapy called cognitive behavior therapy in which a child learns how to control the habit. In addition, medications, such as antidepressants, may also help control symptoms.
Alopecia Areata
Alopecia areata occurs when the immune system attacks hair follicles, resulting in round spots of hair loss. The cause of this disorder is currently unknown, but environmental conditions, such as a virus, can sometimes trigger it. According to the American Hair Loss Association, 1 in 1,000 children suffer from this disorder. Although there is no known cure for alopecia areata, a doctor or dermatologist may be able to suggest a medication to lessen its symptoms. With treatment, hair regrowth will generally occur in about a year.
