There is maybe hope that we could somehow trigger something in the body that would grow new hairs, but there is currently no indication this is possible. There will probably be methods to help alleviate it down the line but my guess is no outright cure.
Same thing with ageing. You can't fully cure it 100%, because it's fundamentally a problem of physics i.e. entropy. You can only band aid the problem.
