Preparing for daily life with hair loss requires a realistic, evidence-based approach. Hair loss has many causes: genetics (androgenetic alopecia), hormonal changes, nutrient deficiencies (iron, zinc, vitamin D, B12), stress, or autoimmune conditions. A MyBody-X test can hint at genetic risk variants (e.g., in the AR gene) or nutrient deficits, but it does not replace a medical diagnosis. Practical steps include gentle hair care: mild shampoos, avoiding harsh styling, and heat protection. For diffuse thinning, have your doctor check iron, ferritin, vitamin D, and thyroid function (TSH). Supplements like biotin or zinc are only useful if a deficiency is confirmed – overdosing (e.g., zinc >25 mg/day) can be harmful. Evidence for most 'hair vitamins' is weak. For genetic hair loss (androgenetic alopecia), minoxidil and finasteride are the only well-proven treatments – but finasteride carries potential side effects. A healthy lifestyle with adequate sleep, stress reduction, and a balanced diet supports hair quality. Importantly, not all hair loss is permanent; seeing a dermatologist is the first step. The predictive power of DNA tests for hair loss is limited – they indicate risk, not destiny.
