well every one uses oil differently, my hair for example, soaks most oils up, in small amounts that is. i oil my ends to "seal" the water in, this helps with dryness n breakage. i oil my ends almost every day. after my shower or refreshing/washing my hair, i mix my condish and a little oil in the palm of my hands. then i work it in my hair. the bottom half. i guess i just smooth it in, though i do make sure that the very ends of my hair is totally coated. i can leave the oil in over night/during the day, and my hair doesnt get greasy, i dont get build up from it. my hair just soaks it up.
