"Constructive Living" by David K. Reynolds improved my life more than anything else I have ever read. It's flawed, but amazing.

Highly recommended.
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
