Need to start something...

[Brandle]

I'm 29 yrs old and have been slowly shedding from age 23-24, until recently I think it may be getting a little hastened. More people seem to comment anyways...
which btw, WTF Yes, I do know I am thinning out on top. does anyone else get people asking them this? Honestly... W T F.
I digress...
I have always had fine hairs, but A LOT of them, I had a bushy head of hair until my younger 20s. My fiance and I have recently broken up and I am in need to get back in the game, however my confidence is slightly hindered due to the above stated reason. I would really like to start some treatment before I actually start getting a bald spot on my crown. Temples are inching back as well...

My question, before I dive into heavy research - Dutasteride or Finasteride? Who takes one or the other? Both? What are the occurring side effects, if any? How is the regrowth/seizing of shedding/overall outcome of the product? and do any side effects stick around after you stop the product?

My main concern is the possible sexual side effects... I know this doesn't occur in all people, but that's what this thread is for! Information!

Any info is much appreciated. Thanks in advance!
