Key benefits
- Vibrant pigmented colour — bold, vivid blue expression

Who it's for
Manic Panic High Voltage Rockabilly Blue is ideal for those who want a vibrant blue colour transformation without the commitment of a permanent dye. Best results on pre-lightened, blonde or light brown hair; works best when the canvas is light enough for the pigment to show.
How to use
- Wash hair with shampoo only (no conditioner) and towel-dry until damp
- Apply dye to dry or damp hair using gloves and a tinting brush
- Comb through to ensure even coverage from root to tip
