"...Do not use products that contain mineral oil or petrolatum. Both of these cheap oils clog pores, rob the hair's moisture and can retard hair growth. Natural oils are the best bet. Jojoba and coconut oil are great conditioning oils. Shea butter is an excellent moisturizer. Pomegranate seed oil is my personal favorite. This exotic oil has excellent moisturizing and nourishing properties and is rich in lipids and essential nutrients. These impart brilliant sheen. It is also an excellent remedy for scalp issues such as dandruff and psoriasis, and has natural sunscreen properties."

As Eliza suggested, coconut oil works well and is available.
