Here's a list of things you can use plain old kitchen Olive Oil for:
1) Hair Treatments: Rubbing olive oil in your hair can help keep it healthy and shiny. I usually just rub it on the ends of my hair to help prevent split ends and to keep it from drying out. Most people use it all over their hair and massage it in especially in the roots and tips. You should leave it in you're hair for about 15-20mins. Wrapping a warm towel around your head can help you get the full effect. Some people also recommend wrapping saran wrap around your hair to keep the oil in. It may take a few shampooings to get it all out, but it's definitely worth it.
2) Face Wash/Makeup Remover: I love using olive oil as a face wash/makeup remover. I don't use it every day because I find your skin can get a bit oily (especially if you've got oily skin naturally.) I use it a couple of times a week in the shower or just around my eyes to get my eye shadow off. It's great in the winter when your skin gets especially dry. Make sure you massage it in all over your face (or where you're trying to remove makeup) and wash off with a warm, damp cloth.
3) Shaving Cream: Olive oil is a great substitute for shaving cream! Just rub it all over your legs, shave, and then wash off with warm water or a warm, damp cloth. It leaves your legs feeling moisturized and very smooth.
