Hair testing What it is: This test uses bioresonance technology to examine hair samples. In theory, certain patterns of electromagnetic resonance from a hair sample can tell you if you have food or environmental allergies. The reality: There is no scientific evidence that hair is involved in allergic reactions.
How do forensic techs analyze hair?
How far back can hair detect drugs?
90 days

How reliable is hair analysis for food intolerance?
Is hair or blood better for intolerance testing?
Food allergy testing generally relies on seeing if your blood produces immunoglobulin E (IgE) antibodies in response to certain foods. But some home tests only measure immunoglobulin G (IgG) antibodies. There’s no evidence that this can help diagnose a food allergy. In addition, hair samples don’t contain IgE.
