Absolutely! If mod-cg works for you, do that. Strict CG doesn't work for everyone. Also, it's not like you can't EVER use cones or sulfates, or can't ever straighten your hair - just do so in moderation, and let your hair recover in between.
You may find with regular diffusing you need to add more moisture, and you may find no difference at all! You already do PT's, so maybe you up the LI, or do an extra DT, or and some oil... Or maybe your hair will respond just fine!
I say if it makes your routine/life better, DO IT! If you feel better bc it looks nicer, and your routine is easier, what's the problem?
We can't live for our hair!! (though we may need to remind ourselves of that sometimes! Lol!!)
