Yes, mouthwash is the perfect antidote to dandruff. Mix it 1:1 with some water and add it to your routine. Just wash your hair as you usually would and then after you are done with your routine, rinse with the solution. Let it sit for a couple of minutes before rinsing it out. Make sure however you don’t get any in your eye – that is something we learned the hard way.
This trick will leave your hair feeling incredibly clean and fresh, but be careful, it can be quite drying. If you have dry hair already, only use it when definitely necessary.
