How often can you use hair oil?

You can use hair oil as often as your hair needs it. Healthy hair can handle a small amount of oil daily, for example 2 to 3 drops, to add shine and reduce frizz. Fine or quickly oily hair benefits less from frequent use; in that case, 1–2 times per week is enough, or only on the ends. Ingredients such as argan oil, jojoba oil, or vitamin E are great for nourishment, while lighter-textured oils are better suited for fine hair.
