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.
I love all the Curl Junkie products and use CJ CCCL as my main styler. Still hoping for 2nd day hair....
Every day is a gift
