Here's a list of some recommended carrier oils:

Extra Virgin Olive Oil is one of the best oils for your hair, skin, body, etc. It's filled with antioxidants, and incredibly moisturizing.

Jojoba Oil is excellent due to its chemical makeup similarities to our natural sebum. Excellent for ALL types of skin and hair.

Avocado Oil is highly and super moisturizing, making it perfect for dry, damaged hair.

Castor Oil is said to strengthen hair, but I've always had to dilute it. It's very thick, so don't overuse!
