What It Is The Guerlain x S.Hearts S hair brush Born of an exclusive collaboration with the prestigious Japanese house S.Heart.S, a specialist in professional haircare tools, this brush with a unique ergonomic design is adorned in gold exclusively for Guerlain. Its ultra-resistant waterproof resin design gives it a double use: Everyday use on dry hair or when applying haircare to wet hair to optimize its diffusion and distribution. It is the ideal tool to complete the Abeille Royale ritual for scalp and hair. What It Does A real technical feat, its ergonomic design is inspired by shiatsu techniques, a Japanese beauty treatment technique that uses manipulations and pressure with the fingers to invigorate and relax the skin. Its 376 fibers with massaging heads in two lengths and different thicknesses give it a double action. For the scalp, it stimulates microcirculation to boost hair's vitality from the root. For the hair fiber, gently detangles while reducing static electricity. In a single stroke, it enhances hair and reactivates its shine. How To Use When using dry hair, brush hair with small downward strokes, starting by detangling the ends and gradually moving up towards the scalp. As a final step, brush one last time all along the hair from root to tip. On wet hair, make circular movements over the scalp, working from the top of the forehead to the back of the head, lingering on the temples. Brush Composure Composed of nylon fiber and waterproof resin.
