Yeah, I can't see any other oral anti-androgens coming out either, if you inhibit DHT you'll get the side effects, no matter the drug.
Maybe a new topical anti-androgen will come out that works well; I haven't seen any on the radar. Maybe in 10 years we'll have one "out soon".
I'm hoping for a new growth stimulator (like the testing going on with Brimatoprost). A growth stimulator that really does grow hairs would be very good for the hair loss market - I think it would sell very well even to people not overly bothered by baldness (people who don't generally browse these boards).
A growth stimulator that actually grows hair rather than minoxidil-like peach fuzz would be ideal.
Will we see this in 10 years? I have my doubts. Maybe, again, one will be "out soon".
I don't see any new hair transplant techniques coming out soon. Maybe FUE will just be refined - maybe with robotic surgery (enabling the surgeon to be far more precise) allowing hairs to be implanted closer together.
HM is just a hair transplant with infinite donor. It will be basically a hair transplant - not very dense, the hairs won't grow like normal hair, it would be hard to get a teenage mop of hair, but again it is better than being UCman bald. I think we'll be seeing field trials of HM in 2020. I can see it being like early FUE hair transplant's, where half of the grafts won't make it. Still, the infinite supply will mean you can just go back for more. Strip surgery will be consigned to history, where it belongs.
I can't see most "normal" bald men going for HM - it's still surgery after all. Those who go for hair transplant's will be delighted.
A pill that turns off male pattern baldness completely? I doubt we'll see this by 2020 either - barring a miracle discovery.
All in all? Pretty much the same situation as now - maybe a better Minoxidil, and with better hair transplant's. Not much hope for NW5+'s still.
