rare genetic disorder causing rough skin and permanent hair loss
Keratosis Follicularis Spinulosa Decalvans (KFSD) is a rare genetic skin disorder characterized by the development of rough, spiny papules around hair follicles, leading to scarring and permanent hair loss (alopecia). It typically begins in childhood and can affect the scalp, eyebrows, and other body areas, often accompanied by redness and inflammation.
