There is still a long way to go. This seems to work when the hair follicles are inhibited from growing. We do not know if it will work for male-pattern baldness.
Those hair follicles are likely being inhibited also but whether the same pathway is used will be the focus of more owrk.
If it works, I wonder just how much the companies will charge? Probably depends on how often it has to be applied.
But if it works, they will make billions.
