Apple cider vinegar
Apple cider vinegar is one of the most effective remedies for getting rid of dandruff as its acidic properties change the pH of your scalp, making it harder for yeast to grow.
Mix a quarter cup of apple cider vinegar with a quarter cup of water in a spray bottle and spritz onto your scalp. Wrap your head in a towel and let sit for 15 minutes to an hour, then wash your hair as usual. Do this twice a week.
