I haven't tried Darcy's yet (but love other products from this brand), but the CJ and AIA are my two staple co-washes. As rymorg said, CJDF is great if you have hard water or use the occasional cone; the AIA is perfect for an everday co-wash (works well without stripping my hair) and is affordable and available on the ground.
2c/3a, botticelli/wavy/'swavy (huh?)
fine, dense, normal porosity/elasticity, dry climate
My favorite brands are Kinky Curly, As I am, Curly Kinks, Curl Junkie, and Darcy's Botanicals. Also love sealing with oils (loving argan oil right now) and styling with jelly products (KCCC is my current favorite). Mostly trying to keep it simple!
