If your everyday or cosplay hairstyle needs some oomph, there’s a new trend you might be interested in: glow-in-the-dark hair. I feel like this is perfect for so many costumes – My Little Pony characters, unicorns, fairies, anything radioactive. The rainbow touches make your hair look like a Lite Brite, and that’s no bad thing. The look can be achieved with Manic Panic’s electric shades colors. The formulas are either UV reactive or blacklight sensitive and available in a handful of colors from Cotton Candy to Siren’s Song. You can get details on which specific formulas and shades glow in Manic Panic’s FAQs.
