Coconut oil is probably the best oil you can use on your hair, since it's rich in protein and antioxidants which are directly absorbed by the hair follicle, creating a protective layer for your strands. It is also great if you have an itchy scalp or suffer from dandruff, as it acts as a hair mask by providing intense hydration.
Here's how I use coconut oil: First, I wet my hair completely and ring out the water. Then, I apply 2 tablespoons of the oil onto my scalp and work my way to the ends (you might need a little more depending on your hair length). I wrap my hair in a towel and let the coconut oil sit for an hour. Then I proceed with shampooing my hair twice, or until I feel that I have gotten rid of all of the oil. Conditioning is not necessary after this step. I would recommend doing this once a week or every other week if you have fine hair.
Your hair might feel like it's on the greasy side until your next washing, but that's perfectly normal because, well let's face it, you are putting oil on your hair. Trust me, though: the results are amazing, and I rarely ever use conditioner anymore since I've started incorporating coconut oil into my hair care routine! My hair is just that silky!
