Yes! OI Oil naturally adds shine and moisture to your hair, which helps to tame frizz and nourish strands. This oil won’t weigh down your hair or make it greasy.

We recommend applying OI Oil to your hair after washing and before styling. For added shine and moisture, you can also apply a small amount after styling. OI Oil works on both wet and dry hair. Typically, you only need to apply it during and after styling, but if you feel the need to reapply later, that's fine too. Just be careful not to overdo it—a little goes a long way to avoid making your hair too oily.

Yes! OI Oil works well for all hair types but it is especially beneficial for coarse and damaged hair. Coarse hair can be difficult to manage, being more prone to frizz and sensitive to environmental factors like humidity. The nourishing ingredients in OI Oil will help smooth the texture and control the frizziness of your coarse strands while repairing and preventing damage from styling and coloring.

Although OI Oil has protective properties that make it a styling staple for your hair care routine, we still recommend using a true heat protectant before applying heat. The OI All in One Milk is the perfect complement to OI Oil, helping to hydrate and detangle hair while also providing heat protection for up to 230°.
