These Pro-Approved Spray-On Hair Colors Won't Mess Up Your 'Do This Halloween

Despite what costume-in-a-bag makers (somehow) sell out of leading up to every fright night, dressing up for Halloween as something sexy, naughty, or just plain offensive isn't your only option. For the diehard among us, the holiday means achieving peak scary, authentic, or gritty — whatever the costume calls for. Things like punky hair color or fake blood take precedence over pretty highlighters and rosy cheeks. The only problem? They tend to require products we wouldn’t normally deem fit to touch our skin and hair.
But as we fired away with cheap, spray-in hair color last year at this time — something we would never use on the daily — a truly scary thought entered our minds: would using this stuff (even for just a day) really eff up our hair? Now, with more and more high-end haircare brands offering spray-in glitter and temporary hair color, we’re left befuddled: should we splurge on the good stuff, as we would with our everyday styling products, or are Halloween products okay?
We took our questions to Susan N. Raffy, a cosmetic chemist with more than 30 years of experience in analyzing and formulating skin and haircare products. Ahead, she helps us break down the differences (and similarities) between fancy and wallet-friendly spray-in hair color and glitter. And like any good haunt, the results delight and fright in the most unexpected of ways.
