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. Coarse hair med. density.
Protein sensitive but can use occasionally
Highly porous. Color over grey.
Best 1st day method: Ice Queen!
Stylers: Mix Curls in a Bottle into everything for shine. Terrible pj
Sometimes try roller sets or use a curling brush - classic glamor.
Every day is a gift
