Being off Finasteride + Minoxidil for 6 months

Hello, I am currently thinking about joining the army and I imagine I wouldn't be able to take finasteride during bootcamp. I was wondering if 6 months of being off finasteride would really mess up my hair? If I were to resume finasteride (and all my other treatments) after bootcamp, would my hair grow back to what it was before when I was taking finasteride? How much hair would I lose if I was off finasteride for 6 months? I will also be off of minoxidil as well.
