This one is not as date as the previous hair throwbacks. During Fall 2013, Splashlight hair coloring technique was a trend. I'm not sure if you heard of Caroline Polachek, lead singer for Charlift, but she was famous for this hairstyle. The concept was started by colourist Aura Friedman of Sally Hershberger salon, NYC.
Splashlight: a highlighting technique that emulate the "beam of light" hitting your hair.
Just imagine the horizontal line you see when the sun shines.
As you can see the highlighting technique is meant to emphasize the cheekbones for that "halo" effect.
Splashlight Coloring Rule:
1. It's okay to have more than one horizontal line, but having just one is the iconic look.
2. It shouldn’t be perfectly horizontal around your hair, but rather diagonal and jagged.
3. Placement of the splashlight is important. Don't go too high or too low, ideally, it should be near your jawline.
4. Gradation is one way to make it look natural.
This example of splashlight is less dramatic and the curls soften the sharp horizontal line.
If you can't commit to the horizontal line, you can still try out the splashlight style inspired by Jessica Biel's toned-down version. Play around with the contrast, length and placement!
