This...^ I'm really curious to see how your hairline's holding up because the recovery you've made on your crown is just about the best I've ever seen in a short time span. Very impressive results.
I won't hijack your thread Breaking Bald but to answer this question it's hard to say as it seems i still have further miniaturization around my hairline but it's progression has seem to have slowed down pretty dramatically and I no longer have the inflammation sensations I had a couple months...
Seriously. finasteride gets a bad rap. I've been on finasteride a little over 4 months now and have had zero side effects. I think having NO side effects at all or very mild side effects is significantly more common than having truly adverse side effects. Regardless i'd much rather have a relatively low libido...
Grow some back? lol... Your hairloss isn't the least bit noticeable. You're still a NW1. You're at the "relax and continue to observe" stage. If it gets worse it may be time for finasteride or minoxidil. Otherwise I wouldn't stress about it. Of course you don't wait until you're a NW3 or beyond but don't...
Looks like a NW1 hairline to me. Not perfectly straight across (your's is slightly rounded/angled) but not all NW1's are. As they say "continue to monitor" but at this point i'm not sure you have any signs of male pattern baldness whatsoever.
No telling how well you'll respond until you actually begin treating it and unfortunately it's a waiting game after starting treatments. For what it's worth your hair loss pattern resembles that of bumblebeewang and he managed to go from a NW2 back to 1 on the big 3. Not saying you'll get those...
My worst nightmare is losing the frontal portion of my hairline (forelock) in the early stages of hairloss ala. NW2a or NW3a. That's a pretty jolting aesthetic change to have to endure early on.
In the grand scheme of hairloss this is nit picky. You can easily conceal a thin crown or hair whorl. Not so much the case with your hairline. I'd take a smallish bald spot on the crown with a full hairline any day. Not to say it's a crime for it to bother you but I wouldn't stress about it.
Couldn't give you a completely definitive answer but one thing to take into account is woman's minoxidil concentration tends to be 2%, while mens is 5%. A higher concentration usually leads to better growth.
