Questions people ask about Haarausfall Männer

Common questions about male hair loss focus on causes, prevention, and treatments. Medically, androgenetic alopecia (AGA) in men is driven by a genetic sensitivity of hair follicles to dihydrotestosterone (DHT). This predisposition is polygenic, with variants in the AR gene playing a key role. Stress (elevated cortisol) and oxidative stress (e.g., via SOD2 variants) can exacerbate hair loss but are not the root cause. Evidence linking consumer DNA tests to specific product recommendations is weak – these tests provide background insight rather than clinically validated guidance. Sudden or patchy hair loss requires a medical evaluation to rule out thyroid issues, iron deficiency, or autoimmune conditions. Proven treatments include finasteride, minoxidil, and low-level laser therapy; supplements generally lack strong evidence.
