How Does Crazy Colour Hair Dye Work?



First developed back in 1909 by Eugene Schuller, a French chemistry expert, crazy color hair dye is now a massively popular trend with over 75% of women coloring their hair to rid themselves of their boring natural color. Thanks to the main chemical ingredient, paraphenylenediamine, as well as a number of other substances, hair dye work through a number of different chemical reactions occurring which affect the molecules and pigments of the hair, ultimately changing the color.

What Exactly Is Hair Made Of?

Hair is mainly made up of the protein keratin, which is also found in fingernails and skin, but the color itself depends on the amount of phaeomelanin and eumelanin your natural hair contains. If you’ve got higher levels of phaeomelanin in your system, then you’ll likely have blonde, red, or ginger-colored hair, while eumelanin encourages brown and black tones. If you’re missing these proteins, you’ll have a white or grey coverage.

People haven’t only just begun coloring their hair, in fact, they have been doing it for many thousands of years, although only with chemicals since the 20th century. Before this, people used plants that contained natural dyeing agents like walnut and henna, while others contained ingredients that bleached the hair, such as citric acid. These natural dyes worked by covering the hair shaft with a different color, and while some last through a couple of shampoos, it is generally quite challenging to get long-lasting and consistent results using natural ingredients.

How Temporary Crazy Colour Hair Dye Is Different

One step up from natural coloring is a semi-permanent dye, which works by grasping on to molecules in the hair strand and changing the color of the hair. Using shampoo will eventually remove these molecules from the hair, returning the natural color. Unlike permanent dyes, temporary crazy hair color doesn’t contain the ingredient ammonia, which opens up the hair shaft during dyeing, and this is why the natural hair color remains once the hair is washed enough.

Permanent hair dye reacts inside the hair strand itself, to add or remove color. Most permanent forms of hair have a two-step process which begins by removing the natural color from the hair, before covering it with a layer of the new shade. It is the same process as hair lightening, with the difference of adding that color to the hair afterward, instead of just removing it. Along with ammonia, peroxide is an important ingredient that removes the natural color, breaking the existing chemical bonds in the hair.
