Skin aside, slathering coconut oil on your strands should be fine, right? After all, there's no risk of breakouts... or is there?

While it's commonly recommended as an at-home hair mask and remedy for dry, brittle hair, you want to make sure that it doesn't end up inadvertently causing breakouts on your bod, cautions Barba. "If you are using it in your hair, make sure to thoroughly wash your back, neck, and chest after you rinse it out to remove any excess residue."

If all of this oil info is making your head spin, we don't blame you. A foolproof solution if you want to play it safe? "Choose oil-based products, rather than pure oils," recommends Gohara. "Let the beauty companies do the work for you. They can formulate a cosmetically elegant product that will allow you to reap the benefits of an oil, without having to worry about the downsides."

Plus, because oils have the potential to oxidize (as do most other active skin care ingredients) you want to make sure they've been properly formulated in a way that ensures they're going to remain stable and effective, adds Barba.
