Dandruff is a common hair disorder characterized by the shedding of white or yellowish flakes from the scalp. It is generally associated with an excess buildup of oil and dead skin cells, often exacerbated by conditions like seborrheic dermatitis or dry skin. Dandruff can also stem from fungal infections, such as Malassezia, and is typically managed with specialized shampoos containing anti-fungal or exfoliating ingredients.

Each of the other options represents conditions or changes related to hair, but they do not classify as diseases or disorders in the same context as dandruff. Split ends result from hair damage and are more of a structural issue rather than a disease. Hair loss due to aging is a natural process rather than a specific disorder, while heat damage pertains to the effects of styling practices on hair health. These conditions impact the appearance or structure of hair but do not encompass the specific, ongoing symptoms associated with a disorder like dandruff.
