The rainbow hair color trend has been going strong for years, leaving everyone mesmerized by variations such as mermaid hair, opal hair and oil slick hair—all Instagram-gold trends and all gorgeous. Now, there’s another take on it to put on your radar and, as with every rainbow hair color trend, it’s also super-pretty: geode hair color.


What Is Geode Haircolor?


This variation on rainbow haircolor takes its inspiration from rocks that look ordinary on the outside but look absolutely magical on the inside. That’s because geodes have hollow cavities lined with layers of colorful, crystallized minerals, which you can see for yourself if you crack a geode open. These minerals include quartz, calcite and amethyst, a purple variety of quartz.

So how exactly does a cool rock translate to a hair trend, you ask? According to Refinery 29, colorists have been channeling the colorful layers of geodes into a dreamy, iridescent, amethyst sombre (or subtle ombre) for their clients—giving them haircolor that reflects one or two jewel tones when it hits the light. Amethyst fades into lavender, bright blue, aqua—you get the picture. The results are subtle yet breathtaking.


Geode Haircolor Interpretations


Colorist are taking the geode haricolor trend and putting their own spin on it, producing sombres that aren’t just purple but blue or pink. For a dramatic take on the geode haircolor trend, some colorists are enlisting the help of underlights—a.k.a. peekaboo hair color in the lower layers of hair—to give hair a more obvious resemblance to the cool rock.

This geode haircolor look, created by Redken Artist Laura Carmichael, does just that. Laura has combined purples, blues, pinks and reds found in rocks. When asked about the geode trend and why she loves to try it on colors, Laura commented, “We have been living in the moment of unicorn hair! This look is taking fairy tale inspire hair to colors that are naturally found in gem stones. It’s modern and edgy!”


How Can You Get Geode Haircolor


According to Refinery 29, a geode-inspired look is created by having a professional colorist lighten your hair from the bottom up without bleaching the roots. Then “the lightened hair is lifted to a pale yellow, then is toned to a blondish white using Redken Shades 9v/clear to eliminate yellow,” Cherin Choi from the Benjamin Salon in downtown L.A tells Refinery 29 that to give the haircolors a beautifully blended finish and make the grow-out process easier to manage, she uses this clever technique: “I use a brush and emulsify with my hands to blend the colors.”

For all our salon professionals reading this, Laura shared the City Beats color formula she used to create the look above!

Entire Zone 1: East Village Violet / Midtown Magenta / 3 dots Brooklyn Blue melted into ribbons with Zone 2 being Indigo Skyline and Zone 3 alternating formulas of: 1) West Village Sunset – equal parts clear, 2) Midtown Magenta- clear equal parts, 3) Times Square Teal and 4) Brooklyn Blue with some clear.
