BLOOD WORK FOR HAIR LOSS: WHICH TESTS MAY HELP UNCOVER THE CAUSE?
In this episode of Let’s Talk About It with Kelly, Kelly Ranney sits down with John Ranney, Certified Clinical Trichologist and President of Freedom Clinic Toronto, to discuss blood work that may be considered when investigating hair loss, excessive shedding, or changes in hair growth.
Can low iron contribute to hair shedding? What do thyroid function, vitamin levels, hormones, and overall health have to do with your hair? John explains why blood work can be an important part of a comprehensive hair loss investigation—and why simply being told that your results are “normal” may not always answer every question.
Hair loss can have many possible causes, including genetics, nutritional deficiencies, thyroid conditions, hormonal changes, illness, stress, medications, autoimmune disease, and inflammatory scalp conditions. Blood testing may help a qualified healthcare professional identify or rule out some underlying factors, but the appropriate tests will depend on each person’s symptoms, health history, medications, age, and type of hair loss.
In this episode, you’ll learn about:
• Why blood work may be recommended for hair loss
• Complete blood count and general health markers
• Iron, ferritin, and iron-deficiency concerns
• Thyroid testing and changes in hair growth
• Vitamin D, vitamin B12, folate, and zinc
• Hormonal factors that may affect hair loss
• Female hair loss and menstrual or menopausal changes
• Male and female pattern hair loss
• Telogen effluvium and excessive hair shedding
• Nutritional deficiencies and restrictive diets
• The connection between overall health and hair health
• Why test results must be interpreted in context
• When additional medical assessment may be needed
• The importance of combining blood work with a scalp and hair analysis
John also discusses why there is no single blood test that diagnoses every form of hair loss. A proper investigation may include a detailed medical and family history, scalp examination, assessment of the hair-loss pattern, review of symptoms and medications, and appropriate testing ordered by a licensed healthcare professional.
Blood work is only one piece of the puzzle. Results should never be interpreted in isolation, and supplements should not be started simply because hair is shedding. Taking unnecessary vitamins, minerals, or iron can be ineffective and may sometimes be harmful. Personalized medical guidance is essential.
If you are experiencing unexplained hair loss, sudden shedding, thinning hair, bald patches, scalp discomfort, or changes in your hair’s density, this episode will help you understand which questions to ask and why a thorough, evidence-based investigation matters.
