Olive oil is an old folk remedy for dandruff. When you apply olive oil-based treatments to your scalp, the oil moisturizes dry areas that may be flaking off. Olive oil can soak into thick, scaly areas on the scalp that cause persistent dandruff issues, hydrating them enough to allow them to loosen and release in a large piece instead of smaller flakes. This often puts an end to dandruff issues because the spot can finally heal over.
An overnight olive oil soak is the best way to take care of severe dandruff issues. It allows the oil to really moisturize your scalp. It may leave your hair quite greasy, though, so make sure you have plenty of time to wash it the next morning. To apply an overnight olive oil soak, pour eight to 10 drops of olive oil into your palm and massage it into your scalp. Place a shower cap over your head to keep from staining your sheets with oil and allow the treatment to penetrate your scalp for at least eight hours. Wash out the oil in the morning using a regular or medicated dandruff shampoo.
Hot Oil Treatment
Hot oil treatments work well for mild to moderate dandruff problems and for people who don't have the time to do an overnight soak. Pour about 3 oz. of olive oil into a saucepan and place it on the stove over low heat until it's just barely warm. Wet your hair, then soak a cotton ball or rag in the warm oil and apply it to your scalp, avoiding your actual hair as much as possible. Cover your hair with a shower cap and let the oil treatment soak in for about 30 minutes. Shampoo and condition your hair as normal to remove the oil.
This olive oil rinse contains apple cider vinegar, which can help cleanse your scalp and rejuvenate dull roots. It's best for those who already have greasy hair because the oil is cut with other liquids. Add 2 tbsp. of apple cider vinegar, 2 tbsp. of distilled water and 2 tbsp. of olive oil in a small bowl, and stir them to combine. Wet your hair until it's just damp and pour the rinse over your head, massaging it into your scalp with your fingers. Leave the treatment on your scalp for about 20 minutes, then shampoo your hair as usual.
