Looking for any advice from NC.com saavy stylists on what things I should do before/after coloring?

I know the best is to not chemically process my hair at all, but I also know that there are curlies out there that do very modest highlights or all over color.

I know the chemicals/etc can damage hair so is there anything I can do to combat/lessen the damage? Like a deep treatment or a protein treatment? Before? After? Both?

Any tips appreciated!
