"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. Coarse hair med. density.
Protein sensitive but can use occasionally
Highly porous. Color over grey.
Best 1st day method: Smasters!
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
