Add shampoo. If your ends are very dry and you're dyeing your entire head, don't put dye on your ends. Instead, three minutes before you're supposed to rinse, add two squirts of shampoo into the dye left in the bottle. Shake it up and apply the mixture to your ends. "It dilutes the dye but still gives you a pinch of color and shine," says Louis Licari of the Louis Licari Salon in New York City. Let your hair down : You know how the models in the commercial always have their dye_coated hair artfully twisted up into a bun? Don't do that. "The color won't be even when you rinse it out," says Ionato. "Leave it down until the timer rings."
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.
