Not likely: Alopecia areata is a cellular autoimmune disease. The mother's killer cells do not cross the placenta barrier and therefore will not attack the hair follicles in the fetus. However, the genes that predispose to alopecia areata are inherited and increase the risk of the child or adult developing the condition in the future.
