You can get coconut oil at most groceries, usually near the health food or organic items. Look for extra virgin coconut oil, and keep it in the fridge. It will turn solid, but go back to liquid with the warmth of your hands. I put it in my hair, mostly at the ends, and let it sit for 30 minutes or so, then wash it out. Just make sure you rinse well, or you may look greasy. Then again, I have dry hair and an oily scalp, so it could just be me.
Coconut oil and Moroccan Oil are the two products I swear by. Oh yeah, and Sally Beauty's Wen knock-off. With these three, I can have healthy straight hair or embrace my curls without frizz and frustration.
I'm glad you're enjoying your new hair!
