Get a stunning new look with Manic Panic Deadly Nightshade Hair Colour. This semi-permanent hair color is cruelty-free and vegan. For best results, pre-lighten your hair to a light blonde using Manic Panic Flashlightning Bleach Kit. Deeper shades may give stunning highlights to darker hair. Ready to use, do not mix with peroxide. Wear protective gloves to avoid staining. Apply to clean, dry hair and saturate thoroughly, avoiding the scalp. Cover your hair with a plastic cap and leave on for at least 30 minutes. Rinse your hair with cool water until it runs almost clear. The color fades gradually with each shampoo.
