Citral should be used with caution around seborrheic dermatitis because it is a fragrance ingredient with recognised allergen context. It is not automatically harmful in every product, but scent-sensitive or actively inflamed skin may be more likely to react.

The checked sources do not show that Citral feeds, suppresses or controls Malassezia. Its concentration and the complete scent mixture are not visible from the label alone. Stop a product that repeatedly causes itching, burning or redness and consider fragrance-free options during flares.
