I think our hair properties sound similar except my hair is only med. density. It used to be more, but alas....

Anyway, I am going to try KCCC again - maybe with a little Knot Today which I sort of gave up on the last time I tried it, but couldn't bear to throw it out, so here goes! Glad you posted.
2/c-3a 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
