At the very least use minoxidil. It's benign compared to anti-androgens. Understandable you wouldn't want to jump to finasteride. I was the same way (for 3 years).
Once/if you hit 2.5 or Norwood 3, you'll take the plunge. I call it the 5 stages of finasteride (very similar to the 5 stages of grief)
1.)denial - This cant be happening to me, I don't want to take this potentially penis killing drug
2.) anger - Screw you dad for your genes, screw you mom
3.)bargaining - Maybe I can just try minoxidil and these natural supplements? it might work
4.)depression - fcukk, i've hit 2 - 3.5
5) acceptance - well, might as well jump on finasteride. This hairloss is killing me inside.
6.) Profit??? - Hair regrowth!?
7.) Sexy ladies. - pure sex.
Damn...this hit too close to home, I'm currently between stage #2 and #3, except I'm only considering "natural" ways of maintaining what I have.
