Alopecia Areata is a common autoimmune disorder that often results in unpredictable hair loss. It affects roughly 2% of the population. In the majority of cases, hair falls out in small patches around the size of a quarter. For most people, the hair loss is nothing more than a few patches, though in some cases it can be more extreme. Sometimes, it can lead to the complete loss of hair on the scalp (alopecia totalis) or, in extreme cases, the entire body (alopecia universalis). The condition can affect anyone regardless of age or gender.

Below are ways you can talk about Alopecia Areata with children of various ages.
