You are treating the hair, not the hormone
Every method you have tried removes the hair that is already on your face. Waxing, threading, plucking, and laser all clear what is there today. Not one of them changes the message telling the follicle to grow the next one.
So you get a smooth week, then it returns, and you start over. It is like bailing water out of a boat while the tap is still running. The water on the floor was never the real problem.
