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 blue colour — saturated pigment for a true statement 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 — Bad Boy Blue

Bad Boy Blue is a bold, deep electric blue shade — a true statement Manic Panic classic that channels rock-and-roll energy and creative expression. 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. Equally striking on full-head colour and creative streaks.

Who it's for

This semi-permanent dye is for anyone who loves bold, expressive hair colour — particularly those experimenting with vivid blues for the first time, fans of alternative and creative styling, or anyone wanting to refresh existing blue-toned hair. The cruelty-free, vegan formulation also appeals to ethical beauty enthusiasts.

How to use

1. For most vivid results, start with clean, lightened hair (medium-blonde base or lighter)
2. Wear gloves and protect clothing/surfaces — semi-permanent pigment stains
3. Apply generously to dry hair, working from roots to ends, using a tinting brush or gloved hands
4. Make sure hair is fully saturated; comb through to distribute evenly
5. Leave on for at least 30 minutes (longer for more intense colour; up to overnight under a shower cap)
6. Rinse thoroughly with cool water until the water runs clear
7. Use sulphate-free, colour-safe shampoo to extend colour life; wash in cool water
