What should you know about folliculitis decalvans hair regrowth?

Folliculitis decalvans is an inflammatory scalp condition that can produce pustules, crusting, soreness, and grouped hairs emerging from one opening. Repeated inflammation may permanently damage some follicles and leave smooth scarred areas. Hair may look fuller where follicles remain active after inflammation is controlled, but a scarred follicle cannot reliably produce a new hair. A dermatologist needs to assess scalp activity and scarring rather than judge recovery from photographs alone.

Arrange dermatology care early and follow the prescribed plan consistently. Avoid picking crusts, harsh chemical treatments, tight hairstyles, and irritating scalp products. Keep a simple record of new pustules, pain, crusting, and areas of thinning so changes are easier to discuss. Treatment may involve antimicrobial medicines, anti-inflammatory care, oral antibiotics for acne in selected situations, or steroid injection into the skin for specific active areas. Do not start these medicines without clinical guidance.

Seek review promptly if pustules, crusting, tenderness, or hair loss continue despite treatment, or if new smooth scarred patches appear. Get urgent advice for rapidly worsening swelling, severe pain, fever, or widespread drainage. A flare should be assessed even when the scalp is not very itchy, because ongoing activity may be easy to miss.

Are there signs of active inflammation or scarring? Which follicles still appear viable? What is the goal and expected monitoring for each treatment? When should we reassess hair density, and could a scarred area need a separate hair-restoration discussion later?
