Know when to go lighter or darker. The rule is as follows: For permanent dye, choose a color a smidge darker than what you want because of the strong developer, says Ionato. With semipermanent dye, however, err on the lighter side of the color you're looking to achieve. "Semipermanent formulas don't have a developer, meaning they get darker and darker the longer you leave them in your hair," says Ionato. "It's safer to choose a color that's a bit lighter from the get_go."
Nude Hair :Nude hair is about balance. "There's an even amount of both warm and cool tones, which cancel each other out to create a neutral color," explains Meri Kate O'Connor, senior colorist and educator at Eva Scrivo Salons in New York City. Bonus: They're very flattering on all skin tones. "Neutral colors are trendy because they're so easy to wear," says O'Connor. Snowlights Hair : With "snowlight" highlights, shimmering pieces of pale blonde scatter across the top of the head like (you guessed it) snow. Try this to get a sparkling lift for your summer hair color, then use Khlorane Sun Lightening Spray with Chamomile and Honey to bring out the highlights.
