The Claim

Dihydrotestosterone contributes to androgenetic alopecia (pattern hair loss) in humans.

Verified by Lenz ·

The Short Version

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.

Caveats

  • Do not interpret this as meaning DHT is the sole cause of pattern hair loss; genetic susceptibility and local follicle sensitivity are major co-factors.
  • Systemic blood DHT levels alone do not reliably predict balding; the relevant biology is largely local to scalp follicles.
  • Benefit from DHT-lowering drugs supports contribution, but it does not prove every case of androgenetic alopecia is driven to the same extent by DHT.
