me and @Ikarus started balding at 14-15. dutasteride didn't stop our hair loss. same thing for @hemingway_the_mercenaryhttps://www.hairlosstalk.com/intera...to-weakest-antiandrogens.123173/#post-1806158
here is my thread on the strongest to weakest oral anti androgens for hair loss. finasteride won't do anything for someone who starts balding before 20. Finasteride is the weakest antiandrogen since it reduces androgenic activity in androgen dependent tissue by only 25%. Dutasteride is a little stronger and reduces androgenic activity by 35%. If you start balding at 14-16 then that means you are likely sensitive to even a little androgenic activity in the body since that is the timeframe when men hit tanner stage 2 in puberty and testosterone levels skyrocket from increased LH and FSH.
if u think DHT causes baldness, you are wrong. Just look at how many men on dutasteride/finasteride for BPH still develop prostate cancer from testosterone alone. This is relevant because prostate cancer gene is encrypted in the Androgen X chromosome, the same chromosome that carries the genes for scalp hair.
