2. Listerine as a Hair Rinse

Listerine can also be used as a hair rinse to help eliminate dandruff and promote a healthy scalp. The antiseptic properties in Listerine help to eliminate bacteria and fungus that can cause dandruff, while the menthol in Listerine helps to stimulate blood flow to the scalp. To use Listerine as a hair rinse, simply mix a cup of Listerine with a cup of water and massage it into your scalp. Leave it on for 5-10 minutes, and then rinse it out. For best results, use Listerine hair rinse once a week.
