I color my hair with chemical dye (L'oreal). I'd suggest a protein treatment. That might help your curls pop. Don't do it immediately after coloring though, since it will make the color fade - it's fine to do after 48 hours.

The CG method doesn't work for everyone, but you do need to give it some more time. It's a lot of experimentation to find out what works best for your curls. Try some protein and keep us posted. Good luck!
2/c-3a Coarse hair med. density.
Protein sensitive but can use occasionally
Highly porous. Color over grey.
I love all the Curl Junkie products and use CJ CCCL as my main styler. Still hoping for 2nd day hair....
