Dandruff primarily affects which of the following?

Hair
Nails
Skin
Scalp

The correct answer is: Scalp

Dandruff primarily affects the scalp, which is the correct answer. Dandruff is characterized by the shedding of dead skin cells from the scalp, often accompanied by itching and irritation. The condition is usually caused by a combination of factors, including dry skin, sensitivity to hair products, or a yeast-like fungus known as Malassezia that thrives on the oils of the scalp. While hair does play a role in the overall appearance of dandruff, it is not the hair itself that is affected but rather the skin on the scalp from which the flakes originate. Nails and overall skin may be related to general skin health or other conditions, but they are not directly associated with dandruff, which is specifically a scalp issue. Therefore, the focus on the scalp as the primary area impacted by dandruff makes this answer the most accurate.
