How to Prevent Dandruff
If you have a skin condition like psoriasis or eczema that affects your scalp, dandruff may be difficult to prevent. But for many people, a few basic steps can reduce the likelihood of this itchy condition.
Shampooing daily can help reduce the amount of dandruff you experience, especially if you have an oily scalp. Make sure to rinse your hair thoroughly after shampooing -- soap residue can irritate your scalp. After you shower, be sure to brush your hair, starting at your scalp and working outward to distribute oil from the scalp along the hair strands [source: WebMD].
Stress can also cause dandruff. Stress affects the entire body, so it can make you more susceptible to many conditions and trigger or worsen dandruff symptoms. Managing the stress in your life is one way to decrease your likelihood of getting dandruff [source: Mayo Clinic]. Other simple steps for reducing your risk of dandruff include cutting back on hair styling products, which can build up on your scalp and increase oil, eating a healthy diet -- especially one high in zinc, vitamin B and certain types of fat -- and getting some sun [source: Mayo Clinic].
