Tiffany Rae Grimes is not so much a colorist, but an artist who uses human heads as a canvas. The Dallas stylist has a gift for the avant-garde, matching the most fantastical of clients' requests with colors found only on an acid-enhanced rainbow. Grimes can whip up vanilla-mocha looks faster than your basic lower-back-tattooed ass can order Starbucks, but she's at her best with her signature mermaid looks. Not only is Grimes a color wizard, but her salon's focus is on fragrance- and allergy-free, holistic, eco-friendly and cruelty-free products.
