Mayo doesn't go well with hair. Trust me.

Ok. You seriously need to listen to me. If you ever, EVER, see a recipe for a deep conditioner that calls for mayo, eggs, and olive oil, DON'T EVER PUT IT IN YOUR HAIR!! Because you know what? It makes your hair smell like potato salad and feel really greasy. It does not make shine. It makes grease. And the mayo? Oh, don't expect that to come out after only one wash!! Oh no it won't my dear:) But on the bright side, it's actually really good for your face:) At least mine. Don't use on sensitive skin. Ok?
