Blood work for Hair Loss
Your hair loss might be one blood test away from being explained.
These 5 deficiencies are directly linked to shedding:
∙Iron (ask for ferritin specifically, not just “iron”)
∙Vitamin D
∙Zinc
∙B12
∙Selenium
Most GPs don’t test all five.
Ask for ferritin below 70 ng/mL specifically.
That threshold alone has ended shedding in people who were told their levels were “normal.”
