Dandruff is more than just a nuisance – it’s embarrassing! Salon sprays are costly, but with apple cider vinegar, your dandruff destroyer will cost only pennies per spray. Just mix equal parts (about 1/4 cup each) apple cider vinegar and water in a spray bottle. Spray onto your hair after shampoo, let sit for 15 minutes and rinse. Use twice per week, and you should be flake free in no time. One theory suggests that the acidity in the vinegar makes it harder for the fungus that contributes to dandruff to grow on your scalp.
