Hair dyeing dangerous?

1. Is dyeing your hair harmful? Can you be allergic to certain substances? Is hair dye carcinogenic? Marsja Meijer of the Dutch Cancer Society, Saskia van der Molen of Heel Natural and Marjolein van Oosterom of the Dutch Cosmetics Association give their vision.

Marsja Meijer of the Dutch Cancer Society KWF: "There is no cause for concern."

1. "I understand the questions. We are also sometimes presented with them. That is not illogical, because there are many chemicals in hair dye. However, all ingredients in hair dye must comply. to the EU directives. That means 'not carcinogenic'. " "On the internet you see all kinds of things about the use of hair dye and the allergic reactions that people get. That is possible. You can be allergic to a certain substance in it. That is why you should always test beforehand. That is also stated on the packaging. " "Hair dye contains hydrogen peroxide. This is necessary to be able to color the hair. Hydrogen peroxide also always evokes the image 'harmful', but the amount used in hair dye is not a risk to public health. There is no risk to the use of products. that are inspected according to EU guidelines are no cause for concern. " www.kwf.nl

Saskia van der Molen of Heel Natural: "There is certainly a link between hair dye and cancer."

1. "Researchers who say that hair dyes are safe often work on behalf of manufacturers. And there are just as many studies that claim that hair dyes are indeed unsafe and that a link can be made between hair dye and non-Hodgkin and ovarian cancer. But it remains difficult to attribute disease directly to hair dye. ” "The fact is, the longer the paint lasts, the worse the fabrics. And there really needs to be a lot more truly independent research into the use of certain substances. So it is better to just not take any risks and not use chemical hair dyes. Certainly not if you are pregnant and substances end up in your blood and therefore also in your baby. " "Also avoid hair dye that contains PPD. You can have a very allergic reaction to this substance. PPD is also found in ink cartridges and henna tattoos. What you often see is that people develop an allergy. They have been using the same product for years without a problem and then all of a sudden. it goes wrong. The combination of using hair dye, especially dark shades, and henna tattoos at the same time is completely disastrous. So take a good look at the packaging to see what is in it. " "Also be aware that inscriptions are sometimes misleading. Packaging may contain the word 'natural'. You may think that there are no chemical additives in it, but that is not the case. Manufacturers may already use the indication 'natural'. if they add only 1 percent vegetable ingredients. " "You are in control of the use of hair dye, so why take a risk if you also have natural alternatives. You may have to look a little more into which color or composition is best for you, but then you also have a hair dye. of which you are sure that it does not contain any substances that are harmful.

Marjolein van Oostrum, spokesperson of the Dutch Cosmetics Association (NCV): "Hair color products are safe."

1. "Hair color products are among the best researched cosmetic products and can be assumed to be safe. There is no evidence of a link between the use of hair dyes and cancer." "In the 1990s, a working group of the World Health Organization (WHO) re-examined more than 70 studies on hair dye products, following an American population survey that concluded that a hair dye can cause cancer. lifestyle and certain diseases. " "In that study, however, the cause and effect of hair dye products and getting cancer were not identified. The WHO study confirmed that there is no link between the use of hair dye and cancer. It does not matter whether it is a product for home use or a hair dye from the hairdresser. The product is the same. The only difference is that in the latter case the hairdresser makes the color himself and in different concentrations. " "You can, however, get allergic reactions as a result of PPD in hair color products. It is therefore important to follow the instructions carefully, because you can have no problems for years and suddenly have a very allergic reaction. Especially in recent years we have seen an increase in the allergic reactions to PPD. Often this is due to henna tattoos. It has been proven that these can lead to nasty reactions to hair dyes. If you use both, the risk of allergy is a lot higher. Then the hair color product is blamed, while the cause is actually the henna tattoo. " "And whether coloring your hair is dangerous when you're pregnant? No. But if you're not comfortable with it, just don't do it. That's your choice." www.ncv-cosmetica.nl
