the problem is that in this sector, more than in others, researchers have worked by induction and not by deduction.
Results have been found with minoxidil, finasteride etc etc only by chance or pure intuition.
No one or almost no one has bothered to draw a complete map of the problem, therefore what we can have are exclusively solutions that target a single piece of the puzzle.
In science perfection or complete description of processes is impossible, there will always be something that will escape, but starting with a complete mapping of the reference system would be the starting point for any search for a solution, excluding any luck
