I avoided cones for a long time or used them rarely and considered myself modified cg because I low poo'd once a week. Now I am slowly re-introducing cones when I wear my hair curly. So far - so good. Even the evil c-cone doesn't seem to bother my hair, but I use a mild shampoo for color treated hair which does have sulfates.

I find hot stylers much worse for my hair than cones.
2/c and some 3A.
Protein sensitive but can use occasionally
Highly porous. Color over grey.
Best 1st day method: Super Soaker
Stylers: Mix Curls in a Bottle into everything for shine. Terrible pj
Sometimes try roller sets - classic glamor but I prefer my curls.
Every day is a gift
