Lay opinion vs evidence: Haarausfall Genetik

The claim that hair loss (androgenetic alopecia) can be reliably predicted or reversed by a single genetic test is often exaggerated. While variants in genes like AR and EDA2R show GWAS associations with male pattern baldness, their individual effect sizes are small and clinical utility is limited. Most consumer tests oversimplify polygenic risk and ignore environmental, hormonal, and age-related factors. Evidence is best classified as 'GWAS' – not human-strong. No robust RCT shows that acting on such genetic information changes hair loss outcomes. Therefore, a DNA test may provide a rough risk hint but should not replace a medical workup (ferritin, thyroid, hormones). Be skeptical of marketing that promises personalized anti-hair loss treatments based on a single SNP.
