Dandruff is a scalp condition that causes flakes of skin to appear. There may also be itching.
Most people experience dandruff at some point in their lives, but it is more common from the teenage years up to midlife.
There are various possible causes, including seborrheic dermatitis, allergic reactions, psoriasis, and eczema. An overreaction to Malassezia, a yeast that occurs on the scalp, is among the causes of seborrheic dermatitis.
Various factors increase the risk of developing dandruff, including a person’s age, the weather, stress levels, medical conditions, and choice of hair products.
Poor hygiene is not a factor, but the flakes may be more visible if a person does not wash or brush their hair often.
People often feel self-conscious about dandruff, but help is available.
