Diagnosis
Because DCS can look like other scalp conditions (such as fungal infections, folliculitis decalvans, or lupus), diagnosis can be tricky. A dermatologist may perform:
-
Physical examination of the scalp
-
Dermatoscopy (scalp magnification)
-
Biopsy to confirm inflammation pattern
-
Culture tests if bacterial infection is suspected
Early diagnosis is important to prevent irreversible scarring.
