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."
Here are the most important things to know: You can't avoid chemicals, but you can avoid unnecessary harsh ones. As previously mentioned, everything is made of chemicals. Water, for example, is a chemical compound. So get it out of your mind that chemicals aren't safe just because they're chemicals. There are, however, harsh and potentially toxic chemicals in some beauty products, and while there has been growing momentum in the industry to remove or minimize these ingredients, hair dye is one of the worst offenders when it comes to including some pretty shady and unnecessary chemicals.
