Second probable cause of bladder cancer, hair dyes are concentrates of aggressive chemicals. If chemical compounds dyes are not yet clearly recognized as carcinogenic, allergists-dermatologists report an increase in severe allergic reactions. Powerful natural colorations now exist on the market, no need to hesitate between his health and coloring.
Hair dyes: better to opt for the 100% natural
Bladder cancer is the 11th leading cause of cancer in France with 10,711 new cases per year but this is the second cancer seen in consultation insofar as it is a disease causing many relapses. This cancer augment with age, but 43% occur before 64 years. Environmental causes seem to be the primary responsibility and, besides tobacco smoke is the primary cause of this cancer, fingers often point to aromatic amines, present in hair dyes, to designate them as second factors. The main offending molecule is para-phenylenediamine (PPD), is the primary source of exposure to aromatic amines through chemical hair dyes.
You know how all happens a dye to the hairdresser or even at home, at least 50% of the French have recourse according to national statistics. Against 16% for men. Initially melanin (hair pigment) is lightened with hydrogen peroxide or hydrogen peroxide in the presence of an alkaline agent (ammonia), this allows precursors penetrate into the hair fiber and to color the hair. These are the famous aromatic diamine: diamine paraphénylènes PPD or PTD paratoluènediamine, etc. When the desired color is obtained (it depends on the molecule and the pause time), a shampoo or a cream closes the hair fiber.
If doubt oncologists, allergists are clear
But then, PPD is a substance absorbed by the skin and naturally discharged from the bladder. That is why it has been associated with bladder cancer. If IARC has never ruled in favor of a classification as a carcinogen class 1, other agencies such as INRS produce reports at the salon professionals making mention of an increase in cancers bladder in this very exposed vocational stream to support studies. If the experts do not all agree, at least the allergologes-dermatologists, who are at the forefront to observe the impacts of chemical dyes relate impressive case of immediate allergic reactions and delayed described as chemical burns to the scalp, the eczema, inflammation of the eyes, eyelids, mucous membranes, breathing problems and shock. For its part, the toxicological index of the Committee on Health and Safety (CSST) mentions that cases of poisoning are reported following the application of a tincture (made of several substances including p-phenylenediamine ); symptoms were reported liver damage and spleen, nervous system disorders (headache, asthenia, dizziness) and gastrointestinal disorders. According to the authors, p-phenylenediamine is the cause of these symptoms. When asked, Dr. Audran Avenel, PH dermatologist at the CHU d'Angers says, "it seems that way now allergy reactions" delayed "early onset, within hours after dyeing with a very important edema . We wonder about the importance of these reactions. "
The solution of natural colorations
For Jean-Marc Réty, hairdresser specializing in natural tones and rich with 35 years of experience in hairdressing, chemical colorings, which he used in its infancy and natural colorations have to do anything in terms of compounds. If chemical dyes still contain dozens of allergens recognized, some natural products are 100% respectful of organizations. The products of natural dyes of society eg Color of Earth are the best on the market today, not only in terms of color beauty but also in terms of composition very carefully chosen.
In addition, the designers have developed a detoxification method of the hair prior to dyeing which serves to remove toxins and pollutants preceding chemical dyes that may have remained in the hair or the bulb. Release toxins and other pollutants is not useless, far from it: "it is not for nothing that there is a number greater than 10% of breast cancer cases in dressing compared to the rest of the female population, "says Jean-Marc Réty ...
