Henné Color plant tint is based on henna with different colouring properties: natural red henna, colourless henna or copper-red henna. Depending on the colour, these are combined with other plant parts, such as rhubarb, chamomile, indigo or rosemary. The colours can also be mixed with each other. Unlike chemical dyes that penetrate the hair structure and make the hair dull, brittle and brittle with repeated use, henna only attaches to the outer cuticle layer, surrounds each individual hair with a colour film, forming a protective layer. The natural colour pigments are not affected. The combination of individual hair colour and henna results in a vibrant shiny colour result. This tone-on-tone effect covers first grey hair.
