Colouring hair is very fashionable these days. You can easily see people of all age groups going for hair colouring. People are experimenting with all kinds of colours to look fashionable. It is no longer just natural black or golden people are going for, but they are experimenting with even red, green and blue and coming up with new hair colouring ideas.

Now-a-days, colouring hair is very much popular throughout the world. Now people do not go for hair colouring just to hide their grey hair but to make a fashion statement as well. Young people experiment with many hair colouring ideas. The market for hair colours is huge spreading all over the world.

Some people lighten their hair, which is also known as bleaching or decolouring. This process involves the diffusion of the natural color pigment or arificial colour from the hair. Permanent hair coloring products contain oxidising agent and an alkalizing ingredient. These chemicals raise the cuticle of the hair fibre so the colour can penetrate in the hair fiber. They also facilitate the formation of tints within the hair fibre and bring about the lightening action of peroxide. Normally temporary colours are used to give brighter colors to the hair. It is because temporary hair colourants do not penetrate the hair shaft itself. Instead, these dyes remain adsorbed to the follicle and can be easily removed with a single shampooing.
