Shampoo and conditioner to bring out natural curl

Can I train my hair from shampoo and condition to get natural s curl type hair from a very short hair cut? hi im 17 black male with short buzz cut and want to grow my hair out and shampoo and condition it to bring out the natural curl in my hair, i really want to know if shampoo and conditioning hair will help train it to be curly when it grows out or if i should wait for it to grow longer? also like any tips for shampoo/conditioner to buy preferably something i can buy IN STORE and NOT online
