Manic Panic Ultra Violet Blue Semi-Permanent Hair Dye | Blue Purple

💙💜 BLUE WITH A VIOLET TWIST. Manic Panic Ultra Violet Blue is a vibrant blue semi-permanent hair dye with subtle violet tones running through the colour. The result is an intense, eye-catching blue with a cooler purple edge — perfect for rave hair, festivals, alternative styling and seriously bold colour combinations. ⚡🪩

For the most vivid result, Manic Panic recommends applying Ultra Violet Blue to a level 10 white-blonde base, giving the colour a clean canvas to really show off its blue-violet tones. The conditioning Classic High Voltage formula comes ready to use with no developer required, and the resealable 118ml tub makes it easy to save leftover colour for future touch-ups.
