Loose roots and grown out dreads

So I'm not too concerned at the moment, but I am curious as to what you can do for your roots once your dreads start growing out. I'm basically doing nothing except for separating my dreads every once and awhile. I have mostly natural/ freeform but I also have lots of twist and rip on the bottom section of my hair. What will happen if I just continue to leave my roots alone?

you should leave them alone as it matures they tighten but only as much as is comfy to the scalp u should still fit a fingertip under the roots

but the roots will take care of themselves

forced tightening is what causes balding
