3 published verifications about Dihydrotestosterone Dihydrotestosterone ×
“Obesity in women causes excessive levels of dihydrotestosterone (DHT).”
The evidence does not show that obesity in women causes excessive DHT levels. Studies commonly find that obese women may have higher DHT production or altered adipose androgen metabolism, but faster clearance offsets this, leaving circulating DHT similar or even lower than in lean women. The claim also blurs local tissue findings with whole-body hormone levels.
“Being underweight in men causes a deficiency of dihydrotestosterone (DHT).”
Available evidence does not show that being underweight in men causes DHT deficiency. Research more commonly associates lower DHT with higher body fat or obesity, while underweight-related studies focus on hypogonadism or testosterone and do not directly demonstrate low DHT. The claim makes a specific causal statement that the cited evidence does not substantiate.
“Dihydrotestosterone contributes to androgenetic alopecia (pattern hair loss) in humans.”
Evidence from mechanistic studies and human treatment trials supports DHT as a contributor to androgenetic alopecia. Balding scalp shows androgen-related changes consistent with DHT-driven miniaturization, and drugs that lower DHT, such as finasteride and dutasteride, often slow or improve hair loss. The main caveat is that DHT is not the only factor; genetic follicle sensitivity strongly affects who develops pattern hair loss.
