My genetics are solid (everyone has full heads of hair except my paternal grandfather and maternal great grandfather) but, like everyone else, I can’t be sure that I’ll never develop MPB. I’m currently 21. I identify heavily with my hair. Can I rest assured that if I catch MPB in the bud early, I can expect myself to keep my hair as if I never had MPB in the first place if I keep taking it?
Finasteride works well in men under 25. The younger you are, the better it works, especially if caught early. 21 is an age where I would expect good results.
