Linalool should be approached with caution in seborrheic dermatitis because it is a fragrance ingredient and oxidised forms can contribute to contact allergy. That does not mean every trace amount causes a reaction, but inflamed or fragrance-sensitive skin may be less forgiving.

The evidence concern is fragrance allergy and irritation, not a demonstrated ability to feed or control Malassezia. Concentration, oxidation and the rest of the scent mixture are not visible from the name alone. Stop a product that repeatedly makes a flare itch, burn or redden.
