There is no must regarding your hair. Use it the way you like.
Also I think KY jelly pretty much does the same thing, among others
, and is way cheaper.
I tried CK both soaking wet and on damp hair. It worked pretty well, depending on the humidity, on both.
Hair: 2a or 3a (not sure), very porous and fine as frog hair
Day 1: Cowash and condition with AO GPB, ACV Rinse,
Co-Kra gel (this stuff is fantastic)
Day 2: KCKT, KCCC, plop, KCCC, plop again, air dry
Day 3: Curly Kinks Satin Roots, Coil Jam
Day 4: IAGirl's PT, KBB DT, FSG
Co-Kra gel is my own concoction of okra boiled in coconut milk. It is a cross between FSG and KCCC and leaves my hair very soft and shiny
