When you get out of the shower you can use a leave in conditioner to help manage some of the frizz and help hold and tame your hair more, then you can try styling it in another style besides the afro and your hair won’t become as big with the conditioner in it. You can also try some serums or oils to help with the fizz as well. If you are not opposed to a ponytail you may be able to get the front slicked back and wear it that way? It may look a bit neater (just a suggestion). Keep your hair moisturized to reduce frizz and use good conditioners.  Also you could try a salon and a good hair stylist, get a cut or style that is more manageable than the fro and then just keep it tamed and maintained with conditioners and oils or serums that are good for your hair.
