Discover our liquid-to-foam leave-in mousse, specially crafted to add body and shine to even the finest hair without weighing it down. Enriched with the iconic Roucou oil and chicory root extract, this mousse for fine hair delivers a silky, light bodifying effect that makes your hair look visibly fuller and shinier. With each use, you'll notice your hair is up to 2.3 times shinier. This heat protectant mousse safeguards your hair — whether fine or medium-thick — during blow-drying and styling, offering protection up to 230°C (446°F). How to use Apply OI Soufflé to washed, towel dried hair. Distribute the product evenly through the lengths and ends, avoiding application to the roots. Most hair types and lengths will need 3-4 pumps of OI Soufflé, but if you have very fine hair start with 2 pumps. There is no need to rinse, simply style as required. For fine hair, shampoo plus OI Soufflé will be enough. If your hair is medium texture, you can use OI Soufflé on its own or additionally.
