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-3a Coarse hair med. density.
Highly porous. Color over grey.
I love all the Curl Junkie products. Still experimenting with gels and curl creams. Still hoping for 2nd day hair....
Every day is a gift
