Rather than buy expensive chemical solutions to fight dandruff, give yourself a natural and ‘cheap’ remedy by pouring equal amounts of apple cider vinegar and cooled boiled water into a spray bottle. Shake well. Spray this mixture onto your scalp and hair. Leave for 15 minutes and then wash and condition as normal. Not only does the apple cider vinegar kill of the yeast infection. Yes, dandruff is a yeast infection, it will also restore your scalp back to its natural pH balance and add fabulous shine to your hair. Don’t be put off, it doesn’t smell bad and once you’ve shampooed, your hair will be gorgeous.
