So often trends die out before we all start jonesing for fresh ways to wear them. This is not the case with rainbow hair color—this is a look that’s so unicorn/Lisa Frank/My Little Pony/Rainbow Brightalicious that anyone who grew up in the ’80s or ’90s was simply preconditioned to love it. And we’ve got two new ideas if you’d like to incorporate them into your life: Multitonal pastel roots and a technique called HyperColor. Oh, and the band One Direction is involved. Stay with us…

The first, HyperColor Hair (named after the heat-activated color-shifting clothing that may have been found in the halls of your middle school), was coined by Pravana guest artist Rickey Zito to describe a technique in which he paints different shades so they radiate from a dark base and brighten as they expand away from the root. You can watch his work in action below.


The second is where One Direction comes in. Louis Tomlinson’s sister Lottie recently went for bold roots and revealed the look on Instagram. Based on the six-figure number of likes her photos received, it’s safe to say the masses are into it. Take a look:

This one is easy to DIY with multiple pots of Manic Panic or paint-on products with wand applicators like Streekers.

One word of warning regardless of how you hop on this train: Bright hues show up best on blond hair or strands that have been lightened to platinum or gray first. Brunettes will watch helplessly as the vivid tones get swallowed completely, ruining all their dreams of psychedelic mane happiness.

Now here’s a little bit about celebrity rainbow-hair-lover Gwen Stefani:
