De ce chelesc bărbații odată cu vârsta? Motivul surprinzător pentru care părul dispare de pe cap • Newsweek România

Men experience hair loss due to a combination of genetic predisposition, hormonal influences, and evolutionary processes. The primary cause is androgenetic alopecia, where dihydrotestosterone (DHT) affects hair follicles, leading to their gradual miniaturization. Interestingly, while DHT contributes to hair thinning on the scalp, it can promote hair growth in other body areas, illustrating the paradox of androgens. Evolutionarily, traits that enhance reproductive success in youth may have negative effects later in life, a phenomenon known as antagonistic pleiotropy. Although male pattern baldness is generally cosmetic, it may also signal maturity and experience, although this theory remains unproven.
