Manic Panic Siren’s Song Semi-Permanent Hair Dye | Neon Turquoise Blue Green

NEON TURQUOISE THAT GLOWS. Manic Panic Siren’s Song is a vibrant neon turquoise blue-green semi-permanent hair dye with a seriously electric finish. Under normal light it delivers vivid mythical turquoise colour; under blacklight, it comes alive with a UV glow. Perfect for raves, festivals, clubs and anyone who wants their hair to be part of the light show. ⚡🩵💚

For the brightest colour and strongest UV effect, Manic Panic recommends applying Siren’s Song to a level 10 light blonde base. Because this is a lighter-pigmented shade, darker or unbleached hair won’t produce the same vivid result. The conditioning Classic High Voltage formula comes ready to use with no developer required, and the resealable 118ml tub lets you save leftover colour for future touch-ups.  
