I oil first, skip the wash before, cause i'm lazy, if you want some sort of energizer, you can rub your scalp with lemon juice before you put in the oil, really cool feeling. But just saturate your hair, put it in one of those caps, and then sit under a dryer for 30 mins. After that just wash your hair like normal, it might take up to 3 washes to get it all out, or it might rinse right out, it is finicky.

I found out about this through a bout with headlice in the 8th grade, we couldn't get rid of it, and a neighbor suggest olive oil, and it worked, and made my hair like silk, I've been doing it ever since.
