Stopped using minoxidil after 7 months of usage; I'm 20. Had good hair before applying it. Will it regrow? (Photos)

I have stopped using minoxidil after 7 months of usage I am 20 the results were bad,I had good hair before applying it . I don't have even 40% of the hair that I had earlier now . My scalp is visible from many areas,scalp hair has thinned,hair from my front & temple has almost gone,so I want to ask will I regrow the healthy hair which has fallen because of minox with time in long term, or this situation is permanent now,will I regrow my hair as it was before 7 months good amount of hair.
