Risks and limits of Haarausfall Senioren

Hair loss in seniors is multifactorial: genetic predisposition (androgenetic alopecia), hormonal shifts, nutritional deficiencies (iron, zinc, vitamin D), thyroid disorders, or medication side effects. Direct-to-consumer (DTC) DNA tests, such as those from MyBody-X, can identify certain genetic risk variants (e.g., in the AR gene), but effect sizes are small and predictive value limited. A genetic test does not replace a medical workup – especially sudden or patchy hair loss requires dermatologist evaluation. Microbiome tests may hint at inflammatory gut processes linked to hair loss, but evidence is mostly observational. Key limits: lack of clinical validation for DTC tests in seniors, absence of age-specific reference ranges, and risk of overinterpretation. Balanced nutrition, stress management, and evidence-based treatments (e.g., minoxidil, finasteride) are more reliable than test-driven recommendations alone.
