I'm with you on the EVOO. I use it from head to toe. Cocoa butter. I have a ton of uses for this one too! I'd be all alone on that island, but I would be moisturized and shiny!!
Jojoba oil is my multi-puropse product, I use it on my skin and hair.
I'd also be sure to pack Fruit of the Earth Block Up!, it's an excellent sunscreen/moisturizer.
I'm getting knots in my stomach just thinking about having only two items at my disposal.
Skin - Cetaphil cleanser (this is a new product for me, but I love it)
Hair - Mango and Lime something or other (I can't remember the full name)
