Bald spot on the top of a woman’s head: what to know

A widening part or gradual thinning around the crown differs from a sharply outlined smooth patch. Broken hairs, scale, redness, tenderness, or scarring also change what a clinician will consider.

Gradual thinning across the top can reflect patterned hair loss, while alopecia areata commonly presents as one or more smooth, clearly defined patches. A scaly area containing short broken hairs can occur with a scalp infection. Tight hairstyles, repeated extensions, chemicals, heat, or habitual pulling can injure hairs in a particular zone. A shiny surface with reduced follicle openings may suggest scarring and warrants prompt specialist review.

Photograph the crown in consistent lighting and note whether the patch is expanding. Avoid tight styles, harsh straightening, vigorous brushing, and picking at the scalp. Do not share combs or hats when scale or broken hairs are present. A dermatologist can examine follicle openings, hair-shaft breakage, and the surrounding scalp; they may also ask about recent illness, medicines, menstrual changes, nutrition, and family hair patterns. Treatment should match the diagnosis rather than the location alone.

Arrange an appointment if the area is enlarging, new patches appear, shedding continues, or the skin looks smooth and shiny. Seek prompt care for pain, pus, marked swelling, spreading redness, fever, or a tender boggy swelling. Eyebrow or eyelash loss, nail changes, or other new symptoms should also be mentioned during the assessment.

Ask whether the follicle openings remain visible, whether the pattern appears inflammatory or scarring, and whether scalp testing is needed. Clarify which hair practices to pause, what change would show that treatment is helping, and when the crown should be rechecked.
