About Manic Panic
Manic Panic is the iconic American alternative-beauty brand founded in 1977 in New York City by sisters Tish and Snooky Bellomo. A staple of the punk, rock and DIY beauty scenes for decades, the brand specialises in vivid, semi-permanent hair colours that are vegan, cruelty-free, ammonia-free and PPD-free — the gold standard for safe, expressive at-home hair colour.
Key benefits
- Vivid, intense colour — saturated pigment for a true statement hair look
- Semi-permanent — gradually fades over washes, no long-term commitment
- Conditioning formula — moisturises the hair while it colours
- Vegan and cruelty-free — no animal-derived ingredients, never tested on animals
- Ammonia-free and PPD-free — gentler than permanent dyes
- Direct application — no developer needed; ready to use straight from the jar
Shade
Deep Purple is a rich, bold purple shade with cool, slightly violet undertones — a classic Manic Panic statement colour that flatters a range of skin tones. For the most vivid result, apply to pre-lightened hair (medium-blonde or lighter); on darker bases, the colour tints rather than fully shifts the natural shade.
Who it's for
This semi-permanent dye is for anyone who loves bold, expressive hair colour — particularly those experimenting with vivid shades for the first time, fans of alternative and creative styling, or anyone wanting to refresh existing purple-toned hair. The cruelty-free, vegan formulation also appeals to ethical beauty enthusiasts.
How to use
- For most vivid results, start with clean, lightened hair (medium-blonde base or lighter)
- Wear gloves and protect clothing/surfaces — semi-permanent pigment stains
- Apply generously to dry hair, working from roots to ends, using a tinting brush or gloved hands
- Make sure hair is fully saturated; comb through to distribute evenly
- Leave on for at least 30 minutes (longer for more intense colour; up to overnight under a shower cap)
- Rinse thoroughly with cool water until the water runs clear
- Use sulphate-free, colour-safe shampoo to extend colour life; wash in cool water
