Citronellol should be treated with some caution in seborrheic dermatitis because it is a fragrance ingredient and fragrance-sensitive skin may react. Its presence does not mean a product is automatically unsuitable, but a simple fragrance-free option can be easier during an active flare.

The checked sources do not show that Citronellol feeds, suppresses or controls Malassezia. The practical concern is irritation or allergy within the complete scent mixture. Stop using a product if it repeatedly causes itching, burning or redness, especially in the same application areas.
