Before diagnosing, your doctor will probably perform a physical examination and inquire about your diet, hair care practices, and medical and family history. You might also need to undergo tests such as the following:
- Blood test: It may help diagnose medical conditions that lead to hair loss.
- Pull test: your doctor carefully pulls on several dozen hairs to assess how many fall out, helping to determine the stage of hair shedding.
- A scalp biopsy: involves your doctor scraping skin samples or plucking a few hairs to analyze the hair roots under a microscope. This procedure helps identify if an infection is contributing to hair loss.
- Light microscopy: involves using a specialized instrument to examine hairs cut at their roots. This technique helps detect potential hair shaft disorders.
