This kit presents a dynamic duo: the Izumi Tonic Strengthening Shampoo and the Izumi Tonic Strengthening Conditioner. The shampoo gently cleanses, strengthens, thickens, and reduces split ends, while the conditioner strengthens, thickens, deeply hydrates, brings moisture and radiance, and also significantly reduces split ends, allowing you to achieve stronger, healthier, and more vibrant hair with ease and grace. This holiday season, shu uemura's kits are inspired by the tranquil art of bonseki and are truly crafted for zen. They invite you to take a moment of pause and reconnect with your inner self, transforming your hair while reinventing your inner strength.
