Vinegar is a very effective home remedy for dandruff. Vinegar helps blood circulation near the surface of your skin. Vinegar is also good at fighting bacteria, viruses and yeast ? all of which are common causes of dandruff. Vinegar helps relieve the symptoms of dandruff such as an itchy scalp and flaky dandruff. White vinegar and apple cider vinegar are the most popular types used to fight dandruff. Using a home vinegar treatment for dandruff is very simple. Simply mix a small amount of vinegar with warm water. As a general rule, add just enough vinegar to change the color of the water. For more severe dandruff, you can use a stronger mixture. Gently rub your vinegar solution onto your scalp. You always want to use a gentle circular massaging motion using only your fingertips and not fingernails. Rubbing too hard or scratching can cause more harm and damage to the skin and to your hair. Let the vinegar stay for at least 15 minutes before washing it out. The amount of time you should leave vinegar on your scalp ranges from 15 minutes to several hours. The amount of time depends on how severe your dandruff is and the strength of your vinegar mixture. For a mild mixture, you can leave it on overnight. Simply massage it on as usual and wrap your head with a towel to prevent over evaporation and to keep your pillow dry. Let it work while you sleep. In the morning, you can wash it out using a mild non-medicated shampoo. You can make a stronger vinegar solution by mixing 4 tablespoons of white vinegar + 2 tablespoons of lemon juice. Rinse it out after 30 to 60 minutes. Vinegar treatments can give immediate dandruff relief. But to see long term and lasting results, you should commit yourself to daily vinegar treatments and using mild shampoos (baby shampoos). You should start to see lasting results after about two weeks. Then you can scale back your vinegar treatments.
