Lauryl Glucoside is not automatically unsafe for seborrheic dermatitis, but it deserves a context-dependent answer. It is often chosen as a mild cleanser, yet human patch-test data show that contact allergy to alkyl glucosides, including Lauryl Glucoside, does occur in a small group of people tested for suspected dermatitis.

That allergy finding is not a Malassezia warning and does not mean everyone should avoid the ingredient. Rinse-off time, the full surfactant blend and your own history matter. If a cleanser repeatedly leaves affected skin itchy, red, tight or burning, stop it and consider fragrance-free alternatives or allergy assessment when reactions persist.
