Do you find that the occasional use of sulfate/cone-containing products makes your hair look bad?

I use sulfate-free shampoo/co-wash and cone-free conditioner/styling products most of the time, but occasionally I'll use a sulfate shampoo or put in a bit of smoothing gel w/cones. I've only just started paying attention to my hair routine, so I was hoping that I could get opinions from ladies who have been on routines like this for a while

(My sulfate-free shampoo is the curl Shea Moisture one...anyone know if it can remove cones?)
