Transverse microscopic anatomy of the human scalp. A basis for a morphometric approach to disorders of the hair follicle

Abstract

• Transverse sections of cylindrical scalp biopsy specimens can provide excellent samples for histologic, quantitative morphometric analyses of the follicles and hair. This study describes and illustrates the morphologic details of the normal transverse anatomy of follicular structures, including the various phases of the normal hair cycle.
