How to fix this?

Hi everyone,

I relaxed my hair at the end of October last year. After washing it off I noticed that my roots may have been a little under processed but not too bad. Recently it's almost as if they're becoming more poofier, and I'm not counting the new growth which is my usual 4b hair.

The ends are straighter/smoother even though I applied to my roots first. It's almost time for my second relaxed and I'm unsure what to do about the poofy bits. Should I just add relaxer to them for a much shorter time than my roots?

Can't go to a salon to get it done because I'm unwilling to pay 150$ for someone to put a 20$ product in my hair and half the time they don't know what they're doing.
