Halloween Hair Color Ideas to Match Your Costume

Bride of Frankenstein White Streak

One of the easiest ways to frighten all your friends is to dye a white wavy streak on the side of your head. This jolt of hair color for Halloween works great on almost any type and length of hair. Use temporary white hair spray or a chalk that washes out. For the full freakout, part your hair down the middle and tease it for scary height. You can also pin the streak in place or shape it with a comb. Make sure the look lasts all night with Full Control Anti-Humidity Non-Aerosol Spray.

Black and white are the classic colors, but you can create any high-contrast combo like or red and blue hair color. For ultimate effect and a delectable villain flair: cleanly divide into sections, slick back your roots, and create unruly curls.

Pastel Fairy Hair

If you’re not wearing a scary costume this year, why not go airy and pastel-y? Fairy hair goes with any sort of sweet sprite vibe, and it’s a quick and easy Halloween hair color idea. Start by applying temporary pastel highlights like pink, sky blue or lilac. Then create a gossamer glow with Pure Clean Detangler for impeccably smooth hair and add shimmer with multicolored tinsel or glitter dust. Or go full-on pixie with a flower crown and/or clips shaped like leaves, butterflies or birds. And don’t forget your magic wand!

Unicorn Colored Hair

Like the mythical creature it’s named after, unicorn hair is otherworldly. Go for colors that exist in nature but would not ordinarily be seen on hair, like vibrant lilac, pistachio, and buttercup! Pair these Halloween hair colors with flowing waves. Unicorns have gorgeous manes, so if using a curling iron or other hot tool to create this look, be sure to apply a heat protectant first.
