Scarring Hair Loss: What to Know

Look for smooth or shiny skin where follicle openings are hard to see, especially if the area is expanding. Itch, burning, tenderness, redness, scale, pustules, or crusting can accompany active disease. By contrast, alopecia areata may produce smooth patches without scarring, and male or female pattern hair loss tends to show patterned thinning. Scalp ringworm, telogen effluvium, and traction alopecia each have different clues and treatments.

Avoid tight braids, extensions, frequent chemical processing, and scratching while arranging care. Bring a list of medicines and supplements, describe when shedding began, and mention pain, itch, scale, or family history. A dermatologist may inspect individual hairs with magnification and may recommend a biopsy. Treatment aims to calm the active process; cosmetic restoration is considered separately after the cause is understood. Finasteride treatment is not a universal answer and is only suitable in particular circumstances.

Seek dermatology care soon when loss is rapidly spreading, the scalp is painful or inflamed, or follicle openings appear to be disappearing. Same-day help is appropriate for fever, pus, rapidly increasing warmth, severe swelling, or intense pain. Early attention matters because scar tissue cannot be converted back into a functioning follicle.

Ask what pattern is visible, whether inflammation is active, whether a biopsy is needed, and what signs should prompt an earlier follow-up.
