If you're wondering whether to put hair oil on your scalp or ends, the answer is both! Depending on your hair type, you may need to adjust the amount of oil you use and where you apply it, but as a general rule, it's a good idea to treat your whole head with hair oil.
If your scalp is dry, itchy, or flaky, using hair oil can help to soothe and protect it. Applying a few drops of oil to your scalp before shampooing can also help to loosen any build-up of dirt and debris. When massaging the oil into your scalp, be sure to use gentle circular motions.
On the other hand, if your ends are feeling dry or damaged, hair oil can help to seal in moisture and prevent further damage. When applying hair oil to ends, start with just a few drops and work up from there until you've reached the desired level of coverage. As with the scalp, massage the oil into your ends using gentle circular motions.
