What Causes Dandruff?

Dandruff is a scalp condition that leads to flaking of the skin. Many affect individuals also experience itchiness, but itchiness isn't required for someone to have dandruff. The exact cause of dandruff isn't currently known, though several conditions have been linked to the presence of dandruff. The ways these conditions lead to dandruff vary. Some cause the skin to flake due to dryness, while others may cause texture problems and flaking because of an immune response. Though dandruff isn't caused by poor hygiene, there is a stigma surrounding it. Some dandruff might be more easily visible if an affected individual doesn't brush or wash their hair often.
