Goldwell Topchic Bus hair dye has an improved formula for maximum results. It gives unprecedented brilliance and intensity, evener color results and increased coverage, radiant shine, noticeable smoothness and pleasant smell. Furthermore, Goldwell Topchic Bus has an extra long shelf life after washing several times, but also after intensive UV radiation and after permanent treatment.
Goldwell Topchic can be applied just like other hair color. So first start with the application on the starter and work towards the dots. Ensure that the paint is evenly distributed over the entire hair. Leave for 30-45 minutes. Rinse with lukewarm water after use.
