Tests for hair loss in females

The assessment usually begins with questions about onset, progression, recent illness, stress, nutrition, pregnancy, periods, medicines, family history, and hair practices. A scalp examination checks whether follicles are open, whether hairs are breaking, and whether there is redness, scale, scarring, or a defined patch. A gentle hair-pull assessment or close inspection may add useful information.

Blood tests are selected rather than automatic. Depending on the history, a clinician may consider thyroid, iron-related, nutritional, or hormone testing. A widening part can fit female pattern hair loss; diffuse shedding may fit telogen effluvium. Smooth patches, scale, or pulling suggest other conditions such as alopecia areata, scalp ringworm, or traction alopecia.

Photograph the part and hairline in consistent lighting before the appointment, and bring a list of medicines, supplements, recent illnesses, diet changes, and styling routines. Mention acne, new facial hair, irregular periods, fatigue, weight change, itching, or scalp pain. These details help decide whether blood work, a scalp-focused test, or observation is appropriate.

Avoid stopping medicines or taking extra supplements to influence a result. Ask what each test is checking, whether preparation is needed, and how an unexpected result would change the plan.

Seek prompt assessment for sudden or rapidly worsening loss, smooth expanding patches, scalp pain, marked redness, pus, thick scale, or broken hairs. New facial hair, severe acne, voice change, or a major period change alongside hair loss deserves timely medical review. Fever or a tender, swollen scalp should be assessed urgently.

Ask which diagnosis the examination is considering, which tests are genuinely relevant, whether a normal result would change treatment, and when results should be reviewed. Ask whether a dermatologist, endocrinologist, or another clinician should be involved if several body systems are affected.
