When brown is too safe and red is too overpowering, coppers create a stylish and beautiful shade choice. Created with orange pigments to add a flame-like glow, you’ll be amazed by the control you can achieve with NXT Copper Brown Semi-Permanent Hair Colours. While some coppers can be quick to fade or become washed out, you’ll love the hold and gradual fade of these copper brown hues.
The copper browns are perfect for adding drama and interest to natural brown hair or refreshing the mid-lengths and ends of previously coloured hair. They’re free from ammonia and parabens and have been formulated to last between 18-24 shampoos.
For easy application, apply to clean towel-dried hair and mix one part of the copper brown reflect with two parts of our specialist low peroxide cream developer using a tint bowl and brush. Normal development time is 20 minutes, but adjust if using heat or if the hair has just been permed or straightened. For white coverage mix at a ratio of 1:1.5. Before colouring a client’s hair with NXT copper brown hair colours, you should carry out a patch test. We recommend the hairdresser applies a small amount of dye behind the ear and leaves for a minimum of 48 hours. If redness or irritation occurs the colour service should not be carried out.
NXT mildly-oxidising semi permanent colours are sometimes referred to as tone-on-tone, demi, and quasi-permanent colours. When the Copper Brown shade is mixed with the releaser and applied to the hair, a series of clever chemical reactions occur to deploy the hair colour. Small and medium colour molecules in the dye penetrate the cuticle and in part the cortex to oxidise it and inject new pigments. These are washed out of the hair in 18-24 shampoos.
When the mixture of Copper Brown and the specialist NXT releaser is applied to the hair, it penetrates the cuticle and in part the cortex, which is oxidised by the hydrogen peroxide found in the releaser. The chosen shade then deposits small and medium colour molecules to change the appearance of the hair. As the colour is ammonia free and developer very low in strength, much of the new pigment is closer to the surface. Therefore, these semi-permanent colours have a stunning high shine.
It’s all down to a series of clever chemical reactions. Once the colour pigments, when mixed with the releaser, have penetrated and oxidised within the hair’s cuticle (and to a lesser extent the cortex) the colour molecules from the Copper Brown shade are released into the hair shaft and the new hue is created. These colours are light-reflecting and deliver high shine as most of the colour pigment is deposited closer to the surface.
The semi-permanent colour change occurs in the cuticle and in part the cortex, which is penetrated and mildly oxidised by hydrogen peroxide in the releaser. Small and medium colour molecules in the Copper Brown dye release the new pigments to create a beautiful new hue. As most of the change occurs close to the surface these quasi permanent colours deliver a high shine.
To allow the Copper Brown to change the appearance of the hair, the colour, mixed with the developer first needs to penetrate the cuticle and in part the cortex and oxidise it. Once these chemical reactions have taken place, the small and medium colour molecules and pigments are deposited in the hair structure for colour that lasts for up to 24 shampoos.
NXT Mildly-Oxidising Semi Permanent Copper Brown shades allow you to transform the appearance of your client’s hair through several chemical reactions. The hydrogen peroxide in the releaser allows small and medium colour molecules to penetrate the cuticle and in part the cortex and oxidise it. As much of the pigment in the new colour is close to the surface you’ll be wowed by the high shine – especially on virgin hair.
Colouring hair with NXT mildly-oxidising semi-permanent shades is so simple that it can be easy to forget that there is actually some pretty clever science taking place. The hydrogen peroxide in the releaser, along with the colour pigments penetrates the cuticle and in part the cortex and mildly oxidises it.. Another chemical reaction sees the small and medium colour molecules from the Copper Brown shade deposited into the hair and bond with the hair’s structure to change the appearance of the locks for 18-24 shampoos.
