Manic Panic High Voltage Classic Hair Dye (Rockabilly Blue)

Rockabilly Blue is one of our strongest true, neutral blue dyes. This vibrant, ultra-powerful blue leaves cool tones on virgin, unbleached hair. For head turning results, we recommend lightening hair to a light level 9 blonde and toning hair before use to prevent unwanted hues. Mixable colours and tones: All Manic Panic hair colours are safe to mix to create custom shades, making the possibilities of shades endless! Combine any formula with the manic mixer/pastel-izer to create soft, on-trend pastel hues. Ready to use, no developer required. Semi permanent hair dye: This semi permanent hair dye formula gradually fades in 4-6 weeks because it does not penetrate the cortex of your hair, but simply rests on top of the hair shaft. Cruelty free, vegan formula: This colour cream hair dye features vegan ingredients tested on celebrities, not animals. Made in the USA, hair colour is PPD & ammonia-free, paraben-free, gluten-free resorcinol-free, and phthalate-free. Additional Features: Benefits of Conditioning Hair, Resealable Tub For Longer Use, Comes With Instructions
