In superficial folliculitis, the inflammation is restricted to the infundibular aspect of the follicle, whereas in deep folliculitis the inflammation not only involves the deeper aspect of the follicle, it also extends into the surrounding dermis. Deep folliculitis can eventuate from chronic lesions of superficial folliculitis or from lesions that are manipulated, and may ultimately result in scarring.
