The Paul Mitchell Thicken Up formula delivers thicker, more vibrant locks by infusing thin hair with a lightweight, body-building texture. This styling liquid imbues strands with definition, softness, and a radiant shine, all while shielding them from the damaging effects of UV rays through built-in protection. Suitable for fine hair, Thicken Up's luscious berry fragrance combines red raspberry, strawberry puree, and tropical fruit notes. For optimal results, apply the product to clean, damp hair and experience the benefits of fuller, shinier strands. The company is dedicated to reducing its environmental footprint and has made significant strides in this area, as evident in the new packaging made from post-consumer recycled materials. By 2026, the brand aims to use recycled materials in 30-50% of bottles and jars, as well as 25% in tubes, with the goal of minimizing waste and promoting recyclability. Please note that certain products, such as aerosols and pumps, will continue to be made from virgin materials.
