About Manic Panic

Manic Panic is the celebrated American hair dye brand founded in 1977 in New York by sisters Tish and Snooky Bellomo. Long synonymous with vibrant alternative hair colour, the brand has been a beloved choice for self-expression for over four decades and is celebrated for its vegan, cruelty-free formulas.

Shade

Red Passion is a rich, true red shade — vibrant, fiery and bold, perfect for those who want a high-impact red without orange or pink leanings.

Key benefits

• Vibrant pigmented colour — bold, vivid red expression
• Vegan and cruelty-free — no animal-derived ingredients or animal testing
• No ammonia or peroxide — gentle on hair, no harsh oxidising chemicals
• Semi-permanent — fades gradually over 4-6 weeks for low-commitment colour
• Conditioning formula — helps hair feel cared for, not stripped

Who it's for

Manic Panic High Voltage Red Passion is ideal for those who want a vibrant, high-impact red colour 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

1. Wash hair with shampoo only (no conditioner) and towel-dry until damp
2. Apply dye to dry or damp hair using gloves and a tinting brush
3. Comb through to ensure even coverage from root to tip
4. Leave on for 30-45 minutes (longer for deeper intensity)
5. Rinse thoroughly with cool water until water runs clear
