Many diseases of hair follicles result in alopecia, which is simply defined as any type of hair loss. The alopecias are conventionally grouped into nonscarring and scarring categories. Nonscarring alopecias may be localized or diffuse. Since the follicles are not destroyed in the nonscar-ring alopecias, there is potential for regrowth or return to normal hair density in these conditions. Follicular diseases that result in follicular destruction and permanent hair loss are termed scarring alopecias. There is some confusion in this categorization scheme because some of the nonscarring alopecias can eventuate over many years into areas of permanent alopecia through follicular "drop-out."
