The Good Housekeeping Institute breaks down why: "Other than henna, any commercially available hair dye store_bought for home use or found in salons uses chemical actives for them to work," says Birnur Aral, Ph.D., Director of the Good Housekeeping Institute's Health, Beauty and Environmental Sciences Lab. "By and large, these chemicals are synthesized substances." Even when the packaging claims to be all_natural, organic or chemical_free which is literally impossible because everything, including organic things, are made of chemicals that could basically be an outright lie. This is because the FDA can't do anything about the use of these terms regarding cosmetics.
Choose a cruelty_free brand. Although you may not be able to color your hair with a natural or organic formula, you can make conscious choices when it comes to the treatment of animals and the use of animal_derived ingredients. Manic Panic, which recently celebrated 40 years of making wild hair colors used in both homes and salons, has been cruelty_free for so long that they've actually trademarked the motto, "Tested on celebrities, not animals." And in addition to being free of ammonia, peroxide and PPD, all of the formulas are vegan, prompting PETA2 to name their formulas Best Cruelty_Free Hair Product in several different years.
