Coconut Oil and Olive Oil are the most preferred Oils for dandruff removal. In the case of Coconut Oil, use 3 to 5 teaspoons of it to rub over your scalp, leave it for an hour and shampoo your hair. But it’s a different case with Olive oil. You must rub your scalp with several drops, cover the head properly with a towel or shower cap before you go to bed, and shampoo it in the morning.
