Alopecia areata
Alopecia areata is a condition characterized by loss of
hair usually in a localized patch or multiple patches. The scalp itself is usually perfectly
normal. In alopecia areata, the
body generates an immune attack on the hair follicles, such that the hair stops
growing just below the surface of the skin. Occasionally, the scalp itches slightly,
but usually there are no associated symptoms.
What to expect
The vast majority of children with alopecia areata are
otherwise well. Occasionally, the
hair loss will be great enough that all scalp hair (alopecia totalis) or even
all body hair (alopecia universalis) will be lost.
The course of alopecia
areata (that is, the frequency of hair loss, extent and hair regrowth) is
unpredictable. However, most
children with localized loss eventually experience hair regrowth. Recurrences of the hair loss are not
uncommon.
Treatment
Your child's doctor can encourage hair regrowth by
prescribing a topical medicine, although the response to these treatments is
also unpredictable. If the alopecia
areata is excessive and/or results in a significant cosmetic problem, purchase
of a wig may be advised.
