Can folliculitis decalvans cause scarring alopecia?

Folliculitis decalvans is an inflammatory scalp condition that can cause pustules, crusting, soreness, and clusters of hairs emerging from one opening. Repeated inflammation can injure the follicle permanently. Hair loss may appear as expanding patches with reduced follicle openings, a smooth or shiny surface, or a scarred centre. It often affects the scalp, and active inflammation can occur around the edge of a thinning area. Early control aims to preserve follicles that are still intact.

Arrange a dermatology assessment if scalp pustules, crusts, tenderness, or progressive patchy hair loss continue. Avoid squeezing lesions, scratching crusts, or using harsh oils and treatments that irritate the scalp. Use prescribed washes or medicines exactly as directed and keep a record of flares and photographs taken in similar lighting. A dermatologist may examine the scalp closely and sometimes take a sample to distinguish folliculitis decalvans from other causes of hair loss.

Seek prompt review for rapidly enlarging hair-loss areas, painful or draining pustules, spreading redness, thick crusts, fever, or significant tenderness. Urgent care is appropriate if swelling extends onto the face, you feel unwell, or severe pain develops. Do not wait for a completely smooth patch: loss of visible follicle openings can signal scarring, while active inflammation may still be treatable.

Are my follicles still visible in the affected area? What findings support folliculitis decalvans rather than another scalp condition? Do I need a scalp sample or treatment to control active inflammation? How should I care for the scalp between appointments?
