If you’ve shampooed faithfully for several weeks and there’s still a dusting of dandruff on your shoulders, talk to your doctor or dermatologist. You may need a prescription-strength shampoo or treatment with a steroid lotion.
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.
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.
Get a little sun
Sunlight may be good for dandruff. But because exposure to ultraviolet light damages your skin and increases your risk of skin cancer, don’t sunbathe. Instead, just spend a little time outdoors. And be sure to wear sunscreen on your face and body.
One alternative therapy that seems to reduce dandruff is daily shampooing with tea tree oil. Tea tree oil, which comes from the leaves of the Australian tea tree (Melaleuca alternifolia), has been used for centuries as an antiseptic, antibiotic and antifungal agent. It’s now included in a number of shampoos found in natural foods stores. The oil may cause allergic reactions in some people.
