There is not enough evidence to call Lavandula Hybrida Oil a good choice for seborrheic dermatitis. It adds lavender-like fragrance, not established antifungal treatment, and fragrant essential oils can irritate or sensitise already reactive skin.

Lavender allergy is uncommon but documented in patch-test clinics. That evidence is broader than this exact lavandin oil and does not mean every user will react. Still, during an active facial or scalp flare, a fragrance-free product is usually the easier variable to control, especially for leave-on use.
