Hair Dye Manic Panic Classic High Voltage Shocking Blue 118 ml — Semi-permanent blue shade

Manic Panic Classic High Voltage Shocking Blue 118 ml is a semi-permanent blue hair dye formulated for creative colouring and temporary style changes. Supplied in a 118 ml tube, this dark blue shade with purple undertones can be applied to pre-lightened hair for vibrant results or used on natural hair to add subtle dark blue highlights. The product is vegan-friendly and PPD-free, and the formula includes conditioning components to help maintain hair texture during the wear period.

Advantages

The formula delivers vivid blue tones with purple undertones and conditions hair during application to reduce dryness. Its semi-permanent nature allows colour changes without long-term commitment, and the resealable tube helps preserve leftover product. The dye is suitable for unisex use and includes usage instructions for consistent results.

How to use

Leave the dye on for the manufacturer-recommended processing time, then rinse thoroughly until the water runs clear. For subtle results on darker or unbleached hair, apply to selected sections as highlights or streaks and check colour development during processing.

Usage recommendations

Perform a patch test 48 hours before full application. To maintain colour longevity, use colour-safe shampoos and reduce the frequency of washing; avoid excessive heat styling and chlorinated water where possible. Store the resealable tube in a cool, dry place away from direct sunlight.
