What should you know about scalp hair loss?

Hair may thin gradually at the temples, hairline, or crown, or the part may look wider over time. This pattern can occur with male pattern hair loss or female pattern hair loss. Smooth, clearly defined patches may occur with alopecia areata, while breakage, tenderness, or scale can point toward a scalp problem.

A sudden increase in shedding after an illness, major stress, marked weight change, or another body change can follow a shift in the hair-growth cycle. Telogen effluvium is one possible explanation. Tight braids, extensions, buns, or other styles that pull repeatedly can contribute to traction alopecia. Scalp ringworm may cause scaling, broken hairs, itching, or swollen areas and needs medical treatment.

Arrange a dermatology assessment if shedding continues, becomes noticeable, or is affecting your confidence. Before the visit, note when it began, whether it is diffuse or patchy, and any recent illness, new medicine, dietary change, hormonal change, or stressful event. Mention relatives with patterned thinning and bring a list of products or supplements you use.

Use gentle hair care while you arrange advice: avoid hairstyles that cause pulling or pain, limit harsh chemical processing and high heat, and treat the scalp gently when washing. Do not start prescription hair-loss medicine or high-dose supplements without checking whether it fits your health history. A clinician may examine the scalp and hair shafts and decide whether blood tests or other evaluation is appropriate.

Seek prompt medical advice for rapidly expanding bald patches, painful or very tender areas, marked redness or swelling, pus, crusting, or significant scaling. Arrange an early review if eyebrows or eyelashes are also thinning, or if hair loss comes with fatigue, unexplained weight change, fever, or other new symptoms. A child with patchy loss, broken hairs, or a scaly scalp should be assessed because infection can spread to others.

Urgent care is appropriate for facial swelling, breathing difficulty, or a severe allergic reaction after applying a hair or scalp product. These symptoms need attention independently of the amount of hair shed.

Ask: What pattern of loss do you see? Could a scalp condition, medication, nutritional issue, hormone change, or recent illness be contributing? Should I stop any hairstyle or product? Which treatment options suit my medical history, and when should I expect to reassess progress? If finasteride is discussed, ask about who should avoid it, possible side effects, and how pregnancy-related precautions apply.
