Alopecia areata: This is likely to be the cause of a single bald spot. Get someone in the family to look at it and see if there are any single hairs in the bald area that look like the traditional appearance of an exclamation mark---broad top and narrow at growth point. That isdiagnostic. Trouble is, noone knows cause.
