excessive shedding of dead scalp skin cells
Dandruff, also known as Seborrheic Dermatitis, is a common scalp condition characterized by the flaking of skin. It occurs when the scalp sheds dead skin cells at an accelerated rate, often accompanied by itching and redness. The exact cause is not fully understood, but factors such as an overgrowth of a yeast-like fungus called Malassezia, oily skin, and individual susceptibility play significant roles.
