Myths vs facts: Hormoncheck Männer and Haut

Hormone checks for men are often marketed as a simple fix for skin issues like acne or hair loss. The reality: genetic variants (e.g., in the androgen receptor gene) can influence sensitivity to hormones like testosterone and DHT, but they are not diagnostic. A blood test measuring free testosterone, DHT, SHBG, and possibly cortisol is needed for a clinical picture. Myth: 'High testosterone causes hair loss' – this is oversimplified. The conversion to DHT and receptor sensitivity matter more. Also, claims that a genetic test can prescribe the ideal skincare or supplementation are not supported by randomized trials. Evidence is mixed: GWAS associations exist for androgenetic alopecia, but no RCTs show that genetically guided interventions outperform standard care for skin problems. Caution: Do not self-diagnose; consult a dermatologist or endocrinologist for skin changes or suspected hormonal issues. Consumer tests are not a substitute for medical evaluation.
