The danger of chemical hair coloring
More and more consumers value the health of their hair and skin, yet chemical hair colouring remains one of the most widely used techniques in the hairdressing industry. What many people do not know is that these colouring methods carry significant risks for both the customer and the hairdresser. Chemical dyes contain a combination of aggressive ingredients that penetrate deeply into the hair fibre and the skin barrier, with potentially serious consequences in both the short and long term.
In this article, we explain why chemical colouring can be dangerous, which ingredients you should avoid, and which healthier, safer and more sustainable alternatives exist.
Chemical hair colouring is dangerous: skin problems and health risks
Chemical colouring is dangerous. It is known as one of the leading causes of skin problems within the cosmetics sector. Its negative effect is even greater than that of hair styling products such as gel and hairspray, as well as other corrosive products.
The reason is simple: chemical dyes penetrate the skin layers and the hair structure, where they cause an aggressive chemical reaction.
Typical complaints caused by chemical colouring include:
- irritation of the scalp
- eczema or dermatitis
- itching, redness or burning sensation
- sensitive or damaged skin barrier
Even if the hair is coloured only once every five weeks, the risk of allergies and hypersensitivity remains real. Many people also develop a reaction only after years, when the immune system can no longer tolerate the synthetic substances.
But this is not the greatest danger. Chemical hair colouring contains toxic components, some of which are classified as level 3 mutagens. This means that they are potentially harmful to the genetic structure of cells. The risks can accumulate with repeated use, increasing the health impact over time.
Which harmful ingredients are found in chemical hair colouring?
The list of risky ingredients used in chemical hair colouring is very long. Many of these components are the subject of scientific research because of their potential toxic, allergenic or hormonal effects.
Below you will find an overview of the most problematic substances:
1. Aromatic amines such as PPD and PTD
Examples: para-phenylenediamine (PPD), para and meta aminophenol, para-toluenediamine.
These substances are powerful allergens and often cause severe skin reactions. They can also be absorbed through the skin and circulate in the body.
2. Metal salts and heavy metals
Examples: lead, cadmium, copper, mercury, iron.
These metals accumulate in both the hair and the body. They can cause toxic effects, weaken the immune system and worsen allergies.
3. Toxic preservatives
Examples: parabens, methylchloroisothiazolinone, BHT, phenoxyethanol.
These substances are linked to hormonal disruption, allergic reactions and possible skin irritation.
4. Resorcinol and methylresorcinol
These ingredients work together with oxidants to fix the colour. They are known for their irritating, hormone-disrupting and potentially toxic properties.
All these components can pose a danger to the body. They do not disappear after a single wash. Instead, they can be absorbed through the skin, accumulate in the hair follicles and spread through the bloodstream. In addition, the protective barrier of the scalp is damaged by the colouring.
Hair is also often bleached. Bleaching damages the structure of the hair, as it makes the hair lighter by removing the melanin. Melanin is the pigment that gives the hair its colour. This process makes the hair structure porous, weak and fragile. The result:
- loss of shine
- faster breakage of the ends
- greater sensitivity to damage
- faster fading of the colour
Chemical colouring therefore not only carries risks for the skin and health, but also causes long-lasting damage to the hair fibre.
Replace chemical hair colouring with plant-based colouring
Fortunately, there is a safe, effective and completely natural alternative: plant-based colouring. This type of colouring uses only ground leaves, flowers, bark and plant pigments without synthetic additives. None of the harmful substances mentioned above are added. It is therefore anything but harmful.
The advantages of plant-based colouring:
- contains no toxic or risky ingredients
- respects the natural structure of the hair
- coats the hair fibre instead of damaging it
- nourishes the hair intensively during colouring
- is suitable for sensitive scalps and allergies
Unlike chemical colouring, plant colouring does not penetrate to the core of the hair. It forms a protective layer around the hair fibre, making the hair stronger, shinier and fuller.
Those who choose natural plant colouring choose the health of their hair and skin as well as an environmentally conscious approach.
