Risk factors

Almost anyone can have dandruff, but certain factors can make you more susceptible:

• Age. Dandruff usually begins in young adulthood and continues through middle age. That doesn't mean older adults don't get dandruff. For some people, the problem can be lifelong.
• Being male. Dandruff is more prevalent in males than in females.
• Certain illnesses. Parkinson's disease and other diseases that affect the nervous system also seem to increase risk of dandruff. So does having HIV or a weakened immune system.
