Testing for hair loss may include:

1 Complete Blood Count (CBC) - Checks for anemia or other blood-related issues.

2 Thyroid Function Tests (TFTs) - Assess thyroid hormone levels, as imbalances can contribute to hair loss.

3 Hormonal Panel - Tests for hormones like testosterone, DHEA-S, and others that may impact hair growth.

4 Iron and Ferritin Levels - Low iron can lead to hair loss, so testing these levels is essential.

5 Vitamin D and B12 Levels - Deficiencies in these vitamins can contribute to hair problems.

6 Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH) - Helpful in evaluating hormonal imbalances.

7 Cortisol Levels - High stress levels can contribute to hair loss, so cortisol testing might be beneficial.

8 Scalp Biopsy - A dermatologist may perform a scalp biopsy to analyze hair follicles for abnormalities.

9 Hair Pull Test - A simple test where hairs are gently pulled to assess hair loss severity.

10 Trichoscopy - Examines the scalp and hair using a specialized device for detailed analysis.

Always consult with a healthcare professional or dermatologist to determine which tests are most relevant to your specific situation.
