When putting products in try raking them thorough with your fingers also a deman brush helps with clumping the curls and fighting frizz hope this helps 
If parts of your hair are still straight from the relaxers, then the curls won't come back unfortunately. But that doesn't mean that you have to big chop. You can transition by doing braidouts, flexirod sets, protective styles, etc. that will help you hide the straight parts and blend them with the curly. As your hair grows, you can slowly cut off the straight ends. Make sure you deep condition and do protein treatments regularly to avoid breakage.
