6 months post op - Minoxidil after hair transplant?

Hi i transplant my hairs around 6 month ago i want to know should i use minoxidil or not i heared when you use minoxidil your hair keep grow but as soon as you stop it, it start shedding so if i use minoxidil and stop it after a while can it cause transplant hairs shedding ? or it just cause normal hairs shedding ?
