Haircare brand Schwarzkopf Professional has announced the introduction of the OSiS+ Session Label Dust it flex, the first mattifying fragranced powder infused with LAVA ROCK. The fragranced grey powder is perfect for light or dark hair and gives instant flexible volume to any style when applied to the roots or lengths of the hair. With lava rock and silica, the formula also gives hair a matt finish. Glycerine keeps the dry consistency of the powder smooth, lets the style be remodelled at any time and ensures that the powder washes out easily. OSiS+ Session Label Dust it flex will be available from February in Schwarzkopf Professional partner salons, priced at £13.25
