Dyeing hair: methods, risks, alternatives

Whether you want to gently enhance your own hair color, cover gray hair or achieve a complete change in type – hair coloring makes it possible. Here you can find out how to dye your hair correctly, whether dyeing hair is harmful and when it is better to only tone it.

Is hair coloring harmful?

Platinum blonde, highlights or modern color transitions – our hair is very changeable thanks to chemical dyes. The hair coloring process is quite taxing on the hair and scalp.

Chemical substances can also enter the body through the scalp. Some substances in hair dyes are considered allergy triggers, such as resorcinol. Liver and kidney damage cannot be ruled out either. Gloves to reduce the contact area with the dye are therefore a must while coloring your hair.

Aromatic amines are also under criticism. Some products contain them as color precursors. Previous studies have suggested that long-term use of hair dye increases the risk of bladder cancer. However, the investigations were carried out using products from the 1960s and 1970s. It is not certain whether the increased risk of bladder cancer can be attributed solely to the aromatic amines in the hair dyes.

Dye hair without chemicals

The hair can be dyed much more gently with vegetable dyes such as henna , chamomile , wheat, turmeric , walnut shells and indigo. They practically do not cause allergies, do not damage hair and give them natural shine. If you want to dye your hair naturally, you have to be patient, because the application is cumbersome and tedious.

The first step is to achieve the desired shade by mixing different plant colors. For hair coloring, the dry parts of the plant are mixed with water to form a paste and applied to the hair. Depending on the hair structure and the desired color intensity, the paste has to work for up to several hours.

It is usually recommended to intensify the color reaction by applying heat and wearing a foil hood. It is also important to keep the paint paste moist so that it cannot dry out. The paste is then flushed out with water. Only then do you wash your hair several times with shampoo.

Although vegetable dyes are gentler than their chemical sisters, they also have some disadvantages when it comes to hair coloring:

  • limited color choices
  • no complete white coverage
  • no lighter coloring possible
  • Color effect depends on the hair structure
  • complicated application
  • like a tint, vegetable colors continue to wash out with every hair wash

Hair coloring – how it works

If you want to color your hair easily, quickly and permanently, you can hardly avoid oxidation hair colors. These chemical hair coloring agents contain two building blocks that are mixed together: an oxidizing agent, usually hydrogen peroxide, and the coloring paste for the desired shade. The oxidizing agent destroys the natural color pigments and lightens the hair. However, the funds attack the black melanin more than the red. That’s why the products contain blue color pigments – otherwise an orange tinge would appear when you dye your hair.

The new hair color only develops during the exposure time. The dye is not added as a whole, but is formed from small, colorless precursors. Once the mini-molecules have penetrated the hair, a reaction with hydrogen peroxide takes place. Now the color molecules are so big that they can’t get out of the hair.

The new shade is permanent, it cannot be removed by washing your hair . However, the hair grows about one centimeter a month, so that after a while the natural color becomes clearly visible. Then it’s time to dye your hair again.

How often hair coloring is popular depends on personal taste – or on the point at which the contrast between roots and colored hair becomes disturbing.

Tinting – hair coloring light

Hair tinting is gentler than coloring hair with oxidizing agents. The hair gets the same color as the tint itself. Washable tints do not contain any color precursors, but the finished dyes that attach to the outer cuticle of the hair or are so small that they penetrate the hair and color it.

However, gray hair can hardly be covered with it. A tint cannot lighten, it can only make light hair darker. In addition, the hair tint can be washed out – the hair loses the artificial color with every hair wash. A tint is ideal for anyone who only wants to change their hair color for a short time. Or who first want to try out whether they actually like the color they want – dyeing hair “light”.
