Pastel rainbow hair is our favorite variation of the trend — when done well, it looks like a unicorn's mane. And while you may associate light, vibrant strands with warmer weather, you'll want to rock this take on colorful coifs all Winter long. Introducing macaron hair! Shelley Gregory, colorist of Atelier Salon in Las Vegas, created this breathtaking look. "I wanted the hair to look and feel like walking into Laduree, the French macaron shop," Gregory explained.
To create this look, Gregory hand-painted different hues of pastel colors in layers onto segments of hair. It's similar to the sand art technique, but the softer shades leave the client's mane more romantic — not to mention multidimensional and totally dreamy. "The color stands out and looks trendy, but it's still chic and approachable," Gregory explained.
