Can I use extra virgin olive oil everyday as a leave in or do I have to rinse it out?
I have 3c hair
I wouldn't for two reasons: 1st - Continuously building that up would leave my hair really oily, but that's just me; 2nd - Oil doesn't actually moisturize the hair, it's meant to seal in moisture. I'm not sure how your hair would react, but it might end up being more dried out by the time you wash you hair.... BUT if your hair doesn't end up oily or dried out, I don't see any reason why you couldn't use it as a leave in.
