Wash the volume back into your hair with Kérastase Densifique Bain Densite Duo. Inside these two 250ml bottles you'll discover a carefully formulated shampoo that can improve the look of fine or thinning hair. Suitable for daily use, Bain Densite will gently cleanse your hair while making it look thicker & stronger. The special ingredient that helps give your hair a fuller appearance is called Stemoxydine. It's a patented densifying molecule that has been shown to target hair follicles & stimulate hair regrowth. It works by lowering the levels of oxygen around the stem cells near the skin's surface, which creates a better environment for hair growth. It also helps to strengthen existing strands, resulting in hair that has an overall thicker & fuller appearance. The formula is also enriched with hyaluronic acid to give your hair some extra bounce. This nourishing ingredient also moisturises your scalp, resulting in a flake-free finish that will leave your hair looking shiny & healthy from root to tip.
