i love coconut oil! its amazing for my curls. give it ago! you can do it any how you want, just try it and see what works best. i apply it when its wet and when its dry, i use it as a prepoo i mix it with my leave in, (normal condish) i use it over night. somtimes i dont wash it out until next wash day, though sometimes i wash it out striaght away.
it all works for me, same other curlies have to expiroment with it. that goes with all the oils, almond and olive as well, though coconut is my fave hair oil, almond is good on the ends.
same curlies swear by olive oil, and i used to love it as well, but, its too greasy for me now so i dont use it.
i would suggest to use them seperate first and see how they go. then when you know what your hair likes mix them a bit.
dont forget a little goes a long way, so start with a bit and add more.
