I am willing to bet the bald rich don’t care. With the kind of money they have, any one of Bezos, Musk, Buffet, Ballmer can make hair loss a thing of the past. To put this in perspective, $15M was all that Stemson needed to fund their research, chump change for people like Bezos.
Funding will help but hairloss is more of a matter of more science than money you pump into its research. Millions of $$$ of been poured into research and little has churned out. Its just a matter of finding the right chemistry, stem cells, protein, growth factor, etc.
