Inside frizz?

My hair is fairly curly, with ringlets and some loose coils on the very bottom. I have a big issue with my curls clumping with frizz between them. If I try to pull them apart gently, it just ruins the curl. Is there anything I can do to get rid of the inside frizz between my curls? And to prevent the clumps, without causing too much volume/lessened definition (which happens when I rake my fingers through whether wet or dry). Thank you!
