I went back to consistent weekly shampooing around the time of my last BC (summer 2015) or possibly earlier. For coil definition I used to be a big fan of bentonite clay masks but for some reason they stopped working for me. I figured out that I could get the same results from a good cleansing with a shampoo that really removes residue.

These days, I will co-wash in the middle of the week if I feel my hair and scalp needs it. Typically I can get away with a plain water rinse instead. However, my "real" wash day involves sulfate-free shampoo.
