<p><strong>What it is</strong>: A liquid-to-foam leave-in hair mousse that's specially crafted to add body and shine to even the finest hair without weighing it down.</p><p><strong>What it does</strong>: Enriched with iconic roucou oil and chicory root extract, this mousse helps deliver a silky, light bodifying effect that makes hair appear visibly fuller and shinier. It also provides heat protection for up to 446°F (230°C).</p><p><strong>How to use</strong>: Apply to washed, towel-dried hair. Distribute evenly through lengths and ends, avoiding application to the roots. Most hair types and lengths will need 3–4 pumps of mousse, but if you have very fine hair begin with two pumps. There is no need to rinse. For fine hair, shampoo plus mousse will be enough. If your hair has a medium texture, you can use the mousse with your shampoo and conditioner.</p>
