No matter your natural (or Halloween) hair colour, there's a glitter for you in this Sephora Collection Give Me Some Glitter Hair And Body Glitter Set ($10, originally $13). Not only does it already add in clear-drying adhesive so your sparkles are locked down, the light and dark glitters complement shades from blonde to black, and there's a bonus fuchsia that would really pop on reds or browns, too.
