The choice of an anti-dandruff shampoo as a common type of scalp treatment for dandruff is correct because these shampoos are specifically formulated to address the underlying causes of dandruff, such as excess oil production and the presence of a yeast-like fungus called Malassezia. Anti-dandruff shampoos contain active ingredients, like zinc pyrithione, ketoconazole, or salicylic acid, which effectively reduce flaking and soothe itching associated with dandruff.

In contrast, other options like moisturizing conditioners, deep-conditioning treatments, and exfoliating scrubs may provide benefits for hair and scalp health, but they do not specifically target the dandruff condition. Moisturizing conditioners might help with surface hydration but do not address the root cause of dandruff. Deep-conditioning treatments focus on improving the moisture and strength of the hair rather than treating scalp issues. Exfoliating scrubs can help remove buildup but lack the medicinal properties needed to combat dandruff effectively. Therefore, anti-dandruff shampoo is the most suitable option for treating dandruff effectively.
