Can I use the Plantur 39 Colour Blonde products on brown hair to dye it blonde?

The Plantur 39 Colour Blonde products are not used to dye the hair, only tone it. Strong colour pigments gradually build up on the hair and the shade becomes more intense. The longer the Colour Blonde Shampoo is left in, the more effective the result. The use of the Colour Conditioner after washing the hair gives a greater colour brilliance. The Plantur 39 Colour Blonde products are suitable for natural and coloured blonde hair, they gradually give the hair a warm, radiant colour and conceal grey hair. However, the products do not have a lightening effect. Regular use on brown hair can create a slight brilliance due to the build-up of colour pigments.
