Alopecia areata

How many people have alopecia areata?

There are several estimates in the literature of the prevalence of alopecia areata. However, it appears that estimates slightly differ depending on the source. For example, according to older sources used by Medscape Reference, the prevalence in the general population was estimated at 0.1-0.2%, (a range of 1 to 2 per thousand people). According to the National Organization for Rare Disorders (NORD) in 2004, alopecia areata affected approximately 2.5 million individuals in the United States (close to 1% of the population at that time). Authors of an article published in 2017 estimated that about 2% of people (1 in 50) develop alopecia areata at some point in their lifetime.
