Suggest Treatment For Hair Loss

hi I developed very bad daily habits (sleeping 3 am in the morning, skipping meals) since i had been to college . I have lost substantial amount of hair .I also had gilberts syndrome .I once used minoxidil lotion and had severe ED now I am doing fine but hairloss is still prominent ?What should I do?Does Shaving head stop hairloss temporarly because in my case it seems to .And any nutrients u would suggest for regrowth without affecting my sexual performance?
