Why does scalp ringworm cause hair loss?

Hair Loss is a common presentation of Scalp Ringworm. The infection can make hairs fragile near the scalp, so they break off and leave short stubble or bare-looking patches. Inflammation around follicles may also interrupt normal hair growth while the infection is active. Itching and scratching can increase damage. Scale, redness, tenderness, or swollen areas may accompany the loss. Because hair loss has many causes, the pattern and scalp findings need a clinician’s assessment.

Arrange a medical review for new patchy loss, especially when it comes with scale or itching. Treatment for scalp ringworm often includes an oral antifungal because infection can sit within hairs and follicles. Use a separate comb and towel, avoid sharing hats or pillowcases, and wash items as advised. Avoid scratching, tight hairstyles, and harsh products that make the scalp sore. Follow the treatment schedule even if the surface looks clearer.

Seek prompt advice for rapid spread, severe pain, a soft swollen mass, pus, thick crusting, or fever. Return for review if hair loss progresses, new areas develop, or the scalp remains inflamed after treatment starts. A persistent inflamed patch may need a different diagnosis or a change in management.

Ask whether testing is needed, which medicine is suitable, and how to tell treatment is working. Ask when regrowth might be assessed, how to reduce household spread, and whether close contacts or pets should be examined.
