I am assuming this is virgin coconut oil. Sooo...
You could use it in your hair, but you might find this very heavy for a daily oil treatment; however, as a deep oil prep before a wash, the coconut oil should be fine.

Virgin coconut oil is good for cooking or on the hair. "Pure" coconut oil comes from a variety of processes, some of which render it unpalatable and give it a woodsmoke smell.

It just takes a couple of drops in the hands to moisturize the hair. I have given myself deep treatments, and have found that coconut oil comes out easily with light conditioner, but olive oil requires repeated shampooings, which can't possibly be good for the hair.
