Colorization – three degrees of permanence


The offer of the hair coloring agents available at drugstores is beyond grasp. On every package there is information about the degree of permanence, however, not each of us knows what is behind those data.

Below we are explaining the methods of dyes’ effects and their permanence

1st degree of permanence – washable hair dyes.

  • permanence 1 means colorization with wash-out toners. The dye covers a hair’s shell only, thanks to which this method is ideal for trying out a new color or for making hair shine. Such color shampoos consist only of one ingredient, they do not brighten the natural hair color and do not penetrate hair’s structure. Color persists for up to three or four washings. Gray hair is covered only to a minimal extent. Wash-out toners are the mildest way to give your hair a shiny tone. This is why they can be used just after doing perm, as they do not weigh hair.

2nd degree of permanence – the color is gradually fading.

  • permanence 2 stands for coloring agents “tone in tone”. They give hair an intense color. They are oxidative dyes, but with low content of oxidants. They consist of two components that must be combined directly before applying onto hair. They do not contain ammonia that damages hair. Color doesn’t wash out, but after some time it loses some of its intensity. Most of such agents do not brighten hair, because they do not reduce pigments and do not injure hair’s structure. There are some agents, however, that contain hydrogen peroxide: they can produce slight bleaching. Dyeing “tone in tone” persists for about 20 washings.

3rd degree of permanence – permanent coloring.

  • permanence 3 means permanent dyes. They are oxidative dyes with increased content of oxidants, most frequently of hydrogen peroxide. As opposed to colorization “tone in tone”, their usage results in reduction of pigments. Such dyes contain ammonia which penetrates hair and scarifies it. Due to this fact color can get inside hair. After such dyeing hair require special care in order that the color was permanent. Permanent colorization makes most intense color changes possible, because it causes total re-dying of hair. Parting with the new color is not easy. The only way to do it is another re-dying. Or patience – until your own non-dyed hair grows back. And there are also roots that must be dyed every month.
