“—” means no specific record for that ingredient in that jurisdiction's lists — it is not an approval. Restricted ingredients are allowed within limits (concentration, product type, label warnings); a product listing one is not necessarily over the limit. How we check.

Ingredient list from Hera official store, retrieved Oct 17, 2026. Formulas change — check the label on the package you buy.

Fragrance allergens (EU labelling)

This list includes 3 fragrance allergens that the EU requires to be named on the label when present above 0.001% in leave-on or 0.01% in rinse-off products: Benzyl Salicylate, Hydroxycitronellal, Citronellol.
