I have much more faith in Tsuji eventually becoming a cost-effective process than a small molecule cure being developed.
If there is a particularly effective small molecule route I suspect it'd be a series of applications of different molecules during specific windows, and these would have to be somewhat tailored to the individual.
And so maybe a future cream or ointment will come in several variants, like so much shampoo for dry to oily scalps or some such. I can see it all now, the sales person will say, Ah! You want this tube for type b hair loss. That'll be $9.95. And would you like to donate $2 dollars to Dutch refugees displaced by rising sea levels?
