Allercalm from Virbac is specially formulated to clean and soothe sensitive skin. The shampoo supports the skin's natural defences, balancing its natural oils and moisturising. Oatmeal has calming, beneficial properties for red, sensitive skin. Spherulites are multi-layered, microscopic spheres which provide a slow and prolonged release of active molecules. Chitosanide is a biodegradable biopolymer that helps the spherulites attach to the skin and hair, and also has a moisturising effect.
