DIY Natural Hair DyeMake All Natural Organic Hair Coloring At HomeWhen hair color first started to appear in the market, the main active ingredient in them was ammonia, a very potent chemical that changed the fundamentals of the hair frolics, and when I said changed I meant damaged it permanently. Just in last few years, most hair color makers are now offering hair color without the ammonia in them, but does that mean it is all good now? Not really, see, most of them took ammonia out but replaced it with other chemicals like phenylenediamine (PPD), a chemical widely used in the newest type of hair dyes, even those that claim to be natural. It’s a popular ingredient because it helps the new color to look natural and to withstand numerous washings without fading. There are some concerns with this ingredient. The main concern with this ingredient is that it is an allergen, and can create difficult skin reactions on the scalp, ears, or neck-wherever the hair dye comes into contact with your skin. According to the National Institute for Occupational Safety and Health (NIOSH)PPD is potentially capable of causing multiple toxic effects following skin contact. Data from studies of both humans and animals are sufficient to demonstrate that PPD has potent skin-sensitizing properties. Several cases of contact dermatitis have been reported following occupational exposure to dyes containing the chemical. Studies have also identified the chemical as the third most common ingredient, after fragrances and preservatives that can cause contact dermatitis from cosmetics (mainly skin-care products, hair preparations and colorants, and facial makeup products).According to American cancer society, “Many American women, as well as a small but increasing number of men, use hair dyes. You may have heard rumors about a link between using hair dye and getting cancer. Many studies have looked at hair dyes as a possible risk factor for various types of cancer.” Sounds scary enough? Well, it should.
