- Also known as follicular degeneration syndrome, pseudopelade of the
central scalp, and folliculitis decalvans of the central scalp and vertex
- Scarring alopecia typically in African American women thought to be due
to chemicals or heat leading to premature desquamation of inner root
sheath
- Presents as alopecic ill-defined areas with scarring over crown or vertex
with gradual expansion; inflammation might not be appreciated
- Histology: concentric lamellar fibroplasia of involved follicles, perifollicular
inflammation, fragments of hair shaft and granulomatous inflammation

family, i.e. doxycycline)
