Highlight with a toothbrush. Several testers shared a smart trick for subtle results : Use a dye kit two shades lighter than your color and paint on highlights with a clean toothbrush or mascara wand. Place them sparingly where the sun would hit around the hairline and stemming from your part, Hill suggests. Start from the top : Since roots need the most color (and processing time), apply dye there first, then comb through the rest of hair to distribute it. Work in four to six sections, like pros do in the salon, to ensure full coverage.
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.
