corrective relaxer question?

i've used dark & lovely for long time now, but i don't think it likes my hair anymore, unfortuantly. i got a touch up in september and had a lot of underprocessed parts, so i did a corrective in october, and those parts are still underprocessed and i'm if not seeing things, i could swear my hair that was touched up in september is reverting into waves, too.

so, i want to switch to optimum anti-breakage (i was planning on switching to lye, but that wouldn't be a good idea, eh?), but i'm wondering if it's safe that i do the corrective + touch up with this relaxer, or should i try to fix it with dark and lovely one more time?
