In addition to regular shampooing, you can take steps to reduce your risk of developing dandruff:
Learn to manage stress. Stress affects your overall health, making you susceptible to a number of conditions and diseases. It can even help trigger dandruff or worsen existing symptoms.
Shampoo often. If you tend to have an oily scalp, daily shampooing may help prevent dandruff.
Cut back on styling products. Hair sprays, styling gels, mousses and hair waxes can all build up on your hair and scalp, making them oilier.
Eat a healthy diet. A diet that provides enough zinc, B vitamins and certain types of fats may help prevent dandruff.
