It’s up to you to decide whether or not to use permanent dyes, but keep this in mind: pregnant women are strongly advised not to colour their hair, and the Environmental Working Group found that 69% of hair dye products they tested for their Skin Deep database may pose cancer risks. In America, the legal maximum is 2% brands that really try hard to be natural (such as those below) could contain as little as. It should be noted that permanent dark colours will always have some PPDs. Some of the worst offenders? L’Oreal Natural Match (the ‘natural’ refers to your original hair colour, but could easily be misinterpreted) Garnier HerbaShine (yes, it contains bamboo and has no ammonia, but it also contains high levels hydrogen peroxide and chemical fragrance), and Clairol Natural Instincts (again, ammonia free, but packed with other harmful chemicals, including parabens and hydrogen peroxide). Don’t be fooled! Just because the name of a product may sound ‘green and clean’ doesn’t mean it is. Knowing that consumers have become savvy to the dangers of chemicals in hair dye, manufacturers have gone all-out in their attempts to greenwash their products.

A good tip for those living in the Americas would be to buy European or Japanese brands: the EU and Japan have banned many toxic ingredients that are still permitted elsewhere. This ingredient has been linked to development of cancer. Lead has well-known damaging effects on the brain and nervous system.

This is present in some hair colouring products used for gradual darkening, and is another potentially toxic chemical. Animal studies have shown it has toxic effects on the nervous system, respiratory and digestive systems at low doses. It is corrosive, and has been banned from cosmetic use in Japan and restricted in Canada. Hydrogen peroxide is used in hair bleaches. Still, many companies are phasing out this harsh ingredient, which compromises the integrity of the hair shaft, too. However, it is much less toxic than PPD, and only receives a rating of 3 out of 10 for toxicity at the Cosmetics Safety Database. It may also disrupt hormonal function, and lead to hypothyroidism.Īmmonia is irritant to the skin, eyes and respiratory system, and can cause asthma and breathing difficulties. It is classified by the European Union as harmful, irritant to eyes and skin and dangerous for the environment. This receives a nasty 8 out of 10 for danger at the Cosmetics Safety Database. The Cosmetic Ingredient Review Expert Panel has concluded that they are safe for occasional use, provided that the skin is rinsed well after. Persulphates are also toxic when the fumes are inhaled, they cause asthma and lung damage. However, concentrations of only 17.5% have been shown to irritate skin. These include sodium, potassium and ammonium sulphates are present in hair dyes and bleaches, and are used in concentrations of up to 60%. And yes, that difference does mean a lot: it’s the difference between, say, smoking a pack of cigarettes and being beside someone having a smoke.Īnother dangerous chemical group is Persulfates. In mainstream supermarket brands, it can be as high as 5-6%, whereas natural hair dyes use less than 1%. It’s almost impossible to formulate a hair color without PPDs, but the most important factor is the concentration of the chemical. This has been linked to bladder cancer, lung, kidney and nervous system disorders and severe allergic reactions. The most common – and dangerous – of these chemicals is probably PPDs ( p-Phenylenediamine). What should you look for on the label of natural hair dye?
