@kmm179, Haha.. I wish I could.
Honestly looking at these companies is pretty laughable these days. I'm sure actually that the hair transplant industry is going to dominate the ranks in the near future.
Again, bottom line is that Androgenetic Alopecia is incredibly hard to reverse. And late Androgenetic Alopecia seem to reflect an irreversible state anyway. And like you say, we have no clue on how to actually deal with this problem. Not even proper models to go by LOL. Totally f*cking clueless. It's a very cruel hard-wired pathology.
I'm also close to 100% sure that Androgenetic Alopecia won't ever be cured from a drug that acts selectively on a pathway, even a multi angle approach won't do it. And again, late Androgenetic Alopecia in some people is irreversible anyway. Only the creation of new hair follicles will do in this case.
The best treatment wise what we are going to have in the next years is still hitting the Androgen/AR angle as hard as possible + minoxidil + the oh so feminizing 17b-estradiol. The rest will be sub-par to that from the current pipeline.
Regenerative therapy is where it's at in the future. But we are talking at 10+ years easily. That will give you one day a full head of hair and will most likely act as a reversal cure.
Going back to your initial point by the way.. The preventative cure is there already in a broad sense. And I wouldn't be surprised if that is going to deal with Androgenetic Alopecia in the future. We are talking about gene therapy
here;

Quite simply we know that if we silence the androgen receptor to full extent, Androgenetic Alopecia will never proceed. Treatments like RU-58841 and CB-03-01 have their downsides because they are too weak to fully deal with the AR, need to be used continuously, pose the risk of side effects because of systemic accumulation, hypothetically the AR might adapt etc.
Gene therapy? Can take care all of that. In fact in the study here above they used a antisense oligonucleotide and a small interfering RNA to silence the androgen receptor in vivo on dermal papilla cells. The antisense oligonucleotide inhibited AR function 100%.
Imagine something better than castration without the downsides that will work for a long amount of time. Truth being told some things still need to be worked on.. However it's realistic to assume that gene therapy to silence the AR will be a real possibility and it might come sooner than you think. The biggest problem won't be if we can't do it (because enough studies show big promise already also related to AR silencing , and enough gene therapy clinical trials are running related to other stuff), but the biggest problem will be the ethical questions that are going to be asked.
Is it ethical to use gene therapy for a cosmetic problem? Because that is how the public is going to look at it.
But yeah, the current things in the clinical trials are looking weak as hell, can't make anything else out of it unfortunately.
