What Tests Are Needed to Diagnose Hair Loss?

Diagnosing hair loss typically does not require extensive testing. In most cases, a specialist can determine the cause through visual examination. However, certain tests may be recommended if an underlying health issue is suspected.

1. Initial Examination

• A dermatoscope may be used to closely inspect the scalp and hair follicles.

• The specialist looks for signs such as:

  • Miniaturized hairs (a sign of androgenetic alopecia).

  • Exclamation mark hairs (common in alopecia areata).

  • Inflammation or scarring (which could indicate conditions like frontal fibrosing alopecia).

2. When Are Tests Needed?

• If the diagnosis is unclear, additional tests may be required.

• A scalp biopsy might be done in rare cases when conditions like scarring alopecia or unusual hair loss patterns need confirmation.

3. Blood Tests (If Necessary)

• If an underlying medical condition is suspected, a doctor may order blood tests to check for:

  • Thyroid function (TSH, T3, T4) – To rule out thyroid disorders.

  • Iron levels (Ferritin, CBC) – To check for anemia.

  • Hormone levels (DHEA, Testosterone, Estrogen, Progesterone) – Especially in cases of hormonal hair loss.

  • Autoimmune markers – If autoimmune diseases are suspected.

4. What to Expect at Your Appointment

• In most cases, you will receive a diagnosis on the same day without the need for invasive tests.

• If the specialist is uncertain, additional testing (biopsy or blood work) may be recommended.

So, if you're preparing to see a hair loss specialist, you can feel reassured that rigorous testing is usually not necessary, and you’ll likely receive answers right away!
