How it works

When the Black shade is mixed with the hydrogen peroxide (the developer) and applied to the hair, a series of chemical reactions occur to transform the hair colour. The cuticle layer of the hair is opened allowing the colour to penetrate in to the cortex, where it oxidises and swells.

It’s all down to a series of clever chemical reactions. Once the hydrogen peroxide (the developer) has been blended with the colour and it has penetrated and oxidised in the hair’s cortex, the colour molecules from the Black shade are released into the hair shaft and the new hue is created.

The permanent colour change all happens deep in the hair’s shaft, which is oxidised by the hydrogen peroxide. Once the chemical reaction has occurred, colour molecules in the Black dye are exposed to create a beautiful new shade.

To allow the Black to change the appearance of the hair, the ammonia in the colour and hydrogen peroxide in the developer first need to penetrate the cuticle and oxidise in the cortex. Once these chemical reactions have taken place, the colour molecules create a long-lasting colour.

Colouring hair with NXT permanent shades is so simple that it can be easy to forget that there is actually some pretty clever science taking place. Once the ammonia in the colour has softened the cuticle, the hydrogen peroxide oxidises the colour pigments. Another chemical reaction sees the small colour molecules from the Black shade deposited into the cortex which permanently changes the appearance of the hair.

The Black shades only work when mixed with the appropriate developer. This allows the hair’s cuticle to be opened and the colour pigments to penetrate the cortex. Small colour molecules then oxidise and expand within the inside of the hair to give the appearance of a whole new hue.
