I use EVOO in my DT's, and sometimes as a pre-poo.
I use EVCO as a pre-poo way more commonly than EVOO, especially overnight (when I know I'm washing in the morning). I use it as an additive to LI once in a while, and as an additive to PT's, in that it's suppose to aid in protein retention.
EVCO has some natural SPF qualities.
I find EVCO can be co-washed out where EVOO cannot. (At least for me).
I have put EVCO on dry hair (mainly in the summer when it will stay liquidy - otherwise it makes my hair feel dry when it solidifies in it), but find EVOO on dry hair can be tragic for me!
