Manic Panic High Voltage Classic Semi-Permanent Hair Colour 118ml - Shocking Blue

Manic Panic High Voltage Classic Semi-Permanent Hair Colour 118ml in Shocking Blue is one of the brand's most iconic shades — a vivid, highly pigmented, electric blue that delivers wild, unmistakable colour with the cult quality the punk and alternative-styling community has trusted since 1977. The vegan, ammonia-free, peroxide-free creme glides on smoothly and conditions the hair as it deposits saturated colour.

About Manic Panic

Manic Panic was founded in New York City in 1977 by sisters Tish and Snooky Bellomo, originally inside America's first punk boutique on St Mark's Place. Now stocked worldwide, Manic Panic remains the cult go-to for vivid alternative hair colour — formulated as a deposit-only semi-permanent dye that fades gradually with washes, with no ammonia, no peroxide and a long-standing vegan, cruelty-free pledge.

Key features

• Vivid, electric Shocking Blue shade — semi-permanent direct pigment
• Vegan, cruelty-free; PPD-free, ammonia-free, peroxide-free

Who it's for

For anyone wanting bold, alternative, vivid colour with a low commitment level — perfect for a first vivid-hair experiment, a festival look or a long-term style staple. As a deposit-only colour, Shocking Blue performs best on hair that has been pre-lightened to pale yellow or white blonde for the brightest payoff; on natural medium-blonde hair the result will be a more muted blue.

How to use

1. Pre-lighten or bleach hair to pale yellow or white blonde for maximum vibrancy (use a professional bleach kit and follow its instructions exactly).
2. Wash hair with a clarifying shampoo, towel-dry and ensure it is free of conditioner and styling products.
3. Wear gloves and apply the colour generously and evenly to dry hair, working in sections from root to tip.
4. Comb through to ensure even coverage and leave on for at least 30 minutes (longer for more intensity — up to 2 hours).
5. Rinse with cool water until the water runs clear; use sulphate-free shampoo and cool washes to extend wear.
