What Is Dandruff?
Dandruff means white or yellow bits of dead skin fall from your scalp. You see flakes in hair or on shoulders. Scalp often itches and feels dry. It’s like seborrheic dermatitis but milder—no big swelling.Dandruff is a common scalp concern that can cause visible flakes, itching, dryness, or irritation. Understanding the condition and its common triggers can make it easier to choose an appropriate hair-care routine. Learn more about what dandruff is and what causes it before deciding how to manage recurring flakes.
Who suffers from this hair problem?

Dandruff usually begins after puberty , because during adolescence hormone concentrations are higher and the body produces more oil (due to greater activity of the sebaceous glands). For this same reason, it is strange that dandruff is present in children and the elderly, although it is common in adulthood.Excess oil on the scalp can make hair feel greasy and may contribute to buildup that makes flakes more noticeable. If your hair becomes oily shortly after washing, understanding how to manage greasy hair and excess scalp oil can be an important part of your overall hair-care routine.
It is also more common in men than in women and, likewise, people with immune system problems or neurological conditions such as Parkinson’s are more likely to suffer from it.
What Causes Dandruff?
Dandruff comes from mix of things. Here’s why:
-
Malassezia Yeast Too Much
This fungus lives normal on scalp. It eats scalp oils. Too much makes skin cells die fast and flake. -
Too Much Oil
Oily scalp feeds the yeast. More oil, more flakes. -
Dry Skin
Cold air or low wetness dries scalp. Skin peels like dandruff. -
Product Leftover
Thick gels or sprays clog scalp. Irritates and flakes. -
Bad Reaction to Products
Strong smells or chemicals make scalp red and itchy.
