I'll make a recommendation: Never use coconut oil on your hair, especially vatika. Haha. I made that mistake and I'm still paying for it. It does NOT come out. I've been applying olive oil to my hair and washing every 3rd day for a month now and NOW it's finally coming out. It also dried out my hair horribly.
Ive ben using vatika coconut oil for years, and i manage to wash it out no problem
Tho i wud suggest using shamppos that are more of a gel format rather than a creamy consistency, becos the gel onces form more of a lather and so its easier to get the oil out of the hair, I use herbal essences
