How often should you use leave-in conditioner?

You can use a leave-in conditioner as often as your hair needs it. In general, applying it a few times a week after washing is enough to give your hair extra nourishment and protection. If your hair looks dry, frizzy, or dull, you can use it more frequently, such as between washes. Just be careful not to use too much, as this can weigh the hair down. Ingredients such as glycerin, shea butter, and oils like argan oil or coconut oil help nourish the hair and lock in moisture.
