I was gonna answer with a joke but you actually made me think, me for example, I still have all my hair, so the sensible thing to do was to let it grow, let it grooooow, if you have all your hair in that head of yours then this is the only good option.
now, If you lost hair, I still wouldn't recomend to wear a wig, one day you're gonna be with 1cm of hair and the other you'll have long hair? everybody will notice, you will notice too, personally I can't stand wigs, they're itchy.
depending on your finantial situation I'd get a hair transplant, with the orchi you won't lose any more hair, hormones generally won't make you recover what you lost
