Manic Panic Siren's Song Classic Creme, Vegan, Cruelty Free, Green Semi Permanent Hair Dye 118ml

SIREN'S SONG: Siren's Song is a blue-green dye that glows under blacklight. For best results, we recommend applying to hair that has been pre-lightened to the lightest level 10 blonde. 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 FEE AND VEGAN: 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.
