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.
You must condition when you're done. "If you skip the conditioner step, it leaves the cuticle open and the color keeps working," says Ionato. "So don't be surprised if you end up with much darker hair than you wanted." Don't throw away the conditioner in the kit, and if you do, make sure to use a deep conditioner in the shower after you rinse out the dye.
