How to increase curl pattern in hair with torsion

Hi, I have wavy to slightly curly hair with torsion ( kink) in each hair. This torsion causes frizz and a diffused curl pattern. I don't know how to help my hair. PT does help some but not a lot. I have dense, medium texture, porous hai with torsion ( kink) but my curl pattern is 2 to 3a. I'm trying to control the kink so that the 2b -3a curls will show more. Any suggestion? I don't know if I should read under wavy, curly or kinky areas or porous or what. Please help.
