A lot of people like avocado oil for it's high smoke point and nutritional properties.
I depend of coconut oil for hair treatments. Both are also great for cooking.
A lot of people swear by olive oil, especially EVOO. There's a reason Mediterranean skin is as gorgeous as it is.
"Pulling" oils and different substances is glimmer. Don't bother. There's no science behind it. Eat a normal, relatively healthy diet and you'll get everything you need; use doctor's labs to determine any specific imbalances.
