Attitude Hair Dye – NU METAL Duo
NU METAL is a semi-permanent green & black hair dye duo built for heavy, high-contrast looks — high-pigment Free UV Green paired with the deepest Daring Black. Vibrant on pre-lightened hair, a subtle tint on darker bases.
Vegan, cruelty-free and made in the Netherlands.
Description
Turn it up to eleven. NU METAL pairs high-pigment Free UV Green against the deepest Daring Black — toxic green cutting hard against pure shadow. Heavy, loud and built for the pit. Wear them solo, split them across your head, or blend the two for a smoky green-into-black fade. Free is UV-reactive too, so your greens glow electric under blacklight — made for the venue. Crank it up.
This semi-permanent duo delivers bold, rebellious colour with zero damage. Like every shade in the range, it's nourishing, high-pigment and made without peroxide, PPD or ammonia — bold payoff, healthy hair.
Best results
For the most vibrant colour, apply NU METAL to pre-lightened hair. Both shades show brightest on a light base; on darker, unbleached hair they'll read as a softer, subtler tint.
Always do a patch and strand test before colouring to check how each shade turns out on your own hair.

How to use
- Bleach — For the brightest result, pre-lighten your hair with Attitude Ghosted Bleach. NU METAL shows best on a very light base.
- Dye — Apply your chosen shade evenly to clean, dry or towel-dried hair, working it fully through from roots to ends. For a split look, section your hair and keep Free and Daring on separate sides. Leave in for 30–60 minutes, or follow the pack instructions.
- Care — Rinse until the water runs mostly clear. Expect a little colour bleed during the first few washes — that's normal. Keep your colour fresh for longer with Attitude Holyplex Haircare.
Mix & match
Get creative with your duo. Wear Free and Daring separately, section them for a green-and-black split, or blend them for a smoky green-into-black fade. Both shades fade gradually and can be refreshed or remixed — so the look grows with you.
Always test your mix on a strand first before applying it to your full head.
Good to know
NU METAL is a semi-permanent direct dye. The final result depends strongly on your starting hair colour, porosity, condition and previous treatments. On a light base you'll get the fullest payoff; on darker hair the colours turn softer and more muted.
