Alopecia Areata

Alopecia areata.Alopecia areata is a condition in which a person has hair loss as a result of the immune system attacking the hair follicles. We do not know why this happens. Often, the hair loss involves only a few patches, which are round in shape. Hair loss is usually seen on the scalp, face or body, but is most common on the scalp. Sometimes it can be more extensive.  

About 4 million people in the United States have alopecia. It affects people of both sexes, all ethnic backgrounds and can occur at any age. It is only rarely seen with other autoimmune diseases in children. Alopecia areata often happens once and then there is regrowth of normal hair. Sometimes, recurrent episodes of hair loss may occur with periods of regrowth. This may occur over many years. 

  • Alopecia areata − patches of hair loss, usually in the scalp
  • Alopecia totalis − complete loss of scalp hair
  • Alopecia universalis − complete loss of hair on the head, face and body (may occur very rapidly) 

For limited areas of alopecia, the affected hairs shed and new hair may regrow. No treatment is usually needed because 95 percent of the time the hair will regrow.

Your doctor may prescribe a few medications to try to help the hair to grow. However, there is no good evidence that any of these treatments will guarantee the hair will regrow. These may include:

  • Steroid cream, ointment or solution that is put on the skin where hair loss has occurred
  • Another type of medicine put on the skin, called topical calcineurin inhibitors (Elidel cream, protopic ointment)
  • A form of vitamin A that is put on the skin (topical retinoid)
  • Steroid injections  

Follow the instructions for use very carefully. If the skin gets irritated, or if you have any questions, call your doctor.

There is little evidence that use of oral medicines will produce lasting hair regrowth, and the side effects of these medicines usually outweigh any potential benefit.

Hair may or may not regrow. Hair that is trying to regrow may respond to treatment and continue to regrow. There is little evidence that hair that is not trying or able to regrow can be “made” to regrow by the use of medicines or other treatment.

  • Age of the child: The younger your child is when hair loss starts, the less likely it is to grow back.
  • Amount of hair involved: If your child has many areas of hair loss, it is not likely to grow back.
  • Amount of time: The longer the hair loss continues, the less likely it is to grow back.
