title: Alopecia--a challenge for dermatologists.
abstract: Alopecia is a loss of hair in the areas where it normally grows. It has to be distinguished from atrichia, the congenital absence of hair due to the absence of hair follicles, and hipotrichosis, scarcity or absence of hair in some congenital diseases. Alopecia is either scarring, when the skin appears atrophic, scaling, and smooth and the hair follicles are absent, or nonscarring, when hair loss is not accompanied by the destruction of hair follicles. This paper is a review of all types of alopecia and their features in an attempt to make them easier to identify and differentiate.
