Will I lose all the hair growth progress if I stop using Minoxidil? (photos)

I am a 69 y.o. Woman that suffered hair thinning after hipreplacement surgery. I wear wigs sometimes but notice that I have hair loss around my edges due to friction. I see little hairs around the edges and where the thinning has occurred. I started using minoxidil and have noticed the thinning hair around my edges and top of my head where the hair loss occurred is thickening and the tiny hairs I had before are growing. Will I lose all the hair if I stop treatment?
