What should you know about a sudden bald spot?

Alopecia areata commonly presents with a smooth, sharply outlined patch where hairs have shed. Scalp ringworm may cause scaling, broken hairs, tenderness, swelling, or areas that look inflamed. Tight hairstyles, pulling, chemical treatments, or repeated friction can break hairs and create uneven density. A clinician may inspect the skin, look closely at hair shafts, and ask about illness, stress, medicines, grooming, and family history.

The appearance of a spot does not identify its cause by itself. A patch can enlarge, new patches can appear, or regrowth can begin, so photographs and a symptom timeline can help during the appointment.

Arrange a dermatology assessment, particularly if the patch is expanding or the scalp is scaly or sore. Use gentle washing, pause chemical processing and tight styles, and avoid scratching or picking. Do not apply steroid, antifungal, or hair-growth products to the patch without advice, because the wrong product can obscure the examination or irritate the scalp.

Treatment depends on the finding. A clinician may recommend prescription treatment for inflammation or infection, or simply monitor regrowth. A Hair Transplant is not a first response to a newly appearing patch while an active cause remains uncertain.

Seek prompt care for pus, marked swelling, severe tenderness, fever, or rapidly spreading hair loss. Urgent assessment is appropriate if scalp swelling affects vision or if you feel very unwell. Hair loss with loss of eyebrows, eyelashes, or body hair should also be discussed soon because it may change the evaluation.

Ask whether the patch looks smooth, scaly, scarred, or broken, whether testing is needed, and what signs would indicate infection. Discuss expected regrowth, ways to protect nearby hair, and when to return if the patch changes.
