I have a random bald spot on my head

Alopecia areata can create a smooth, sharply defined patch without obvious scaling. Scalp ringworm may cause scale, itch, broken hairs or tenderness and can spread between people. Tight hairstyles, repeated pulling, harsh chemical processing and rubbing can also damage hair. The pattern, skin surface, broken hairs and changes elsewhere on the body help a clinician narrow the cause.

Photograph the patch in consistent lighting and record when you first noticed it. Avoid tight braids, extensions, scratching and unverified regrowth products until the cause is clearer. Do not share combs, brushes, hats or pillowcases if scaling or broken hairs suggest infection. A clinician may examine the scalp and, when appropriate, test hairs or skin before recommending treatment. Hair Transplant is not usually the first step while an active cause remains uncertain.

Book an assessment if the patch is new, enlarging or joined by other patches. Seek prompt care for pus, marked redness, swelling, significant pain, fever or tender neck glands. Scalp hair loss with extensive scale or broken hairs needs attention because untreated infection can affect other people and may injure follicles.

Ask what features distinguish Alopecia Areata from Scalp Ringworm, whether testing is needed, how to protect household members, and what signs would show that treatment is working.
