My hair is like 4 different textures, Help!

Practically my entire family has straight hair, so up until i was like 14 i didn't even know there were products specifically for curly hair (i was about 3a-b then). I straightened + colored it constantly, and  as a result it got really gross and damaged. Then i stopped, cut it shoulder length and let it be for the most part. Now I've finally found a style that suits me (buzzed everywhere but the top, long part reaches about mid ear) but my hair is somewhat damaged from bleaching, so the curl pattern is super inconsistent, from mild 2a waves in the back to mostly 3a with some 3b in the front. Is there a product that can help make the curls/waves more uniform and defined? Thank you.
