Fixing a bald spot: what to know

Fixing a bald spot starts with finding its cause, because patchy loss from alopecia, infection, or scarring needs different care. A clinician checks the scalp, the skin around the patch, hair shafts, and the pattern of other hair loss. Treatment can range from observation and prescribed medicine to procedures for selected stable patterns.

A smooth, round patch may occur with alopecia areata, an immune-related condition. Scaling, broken hairs, tenderness, pus, or swollen neck glands can point toward scalp ringworm, which needs medical treatment and should not be managed with hair products alone. Loss with shiny skin or absent follicle openings may indicate scarring, where early assessment matters because regrowth can be limited once follicles are destroyed.

Take clear photographs in consistent lighting and note when the patch began, whether it is enlarging, and whether shedding occurs elsewhere. Avoid tight hairstyles, harsh chemicals, and scratching until the scalp has been assessed. Do not share combs, hats, or pillows if infection is possible. A dermatologist may examine hairs or take a sample; a hair transplant is generally considered only after the cause is clear and the area is suitable.

Book prompt care for a rapidly expanding patch, scalp pain, scaling, broken hairs, pus, crusting, fever, or swollen glands. Seek urgent help for facial swelling, severe infection symptoms, or sudden widespread hair loss with feeling very unwell. Early review is especially useful when the scalp looks shiny, inflamed, or scarred.

Ask what pattern the patch suggests, whether testing for infection is needed, when regrowth might be assessed, and which treatments fit your diagnosis. If a procedure is discussed, ask about donor hair, healing, density, and the chance that untreated hair loss could continue.
