Q²M Bathe+ is the world’s first pH neutral shampoo containing SiO₂. Even a quick wash leaves a strong hydrophobic layer, repelling water, dirt and deferring the need for a next wash. The wash itself is a real joy, while the shampoo is very slick and has a scent characteristic of the whole Gyeon range.
