Think of it as a night cream for your hair - the Kérastase 8 hour Magic Night Serum is all about hydration and restoration. As a good moisturiser helps your skin repair itself from the day, this serum nourishes and protects your hair as you sleep. On top of that, it smells like heaven, and its lightweight texture means it’s one of those rare products that suits pretty much all hair types. Fine hair won’t be weighed down, but thicker, coarser hair still gets the extra love it needs. This Kérastase night serum adds definition to curls, and shine and softness to all hair textures. Made with iris root extract and a blend of five vitamins, it’s got some serious punch.
