Attitude Hair Dye – Happy
Happy is a neon UV yellow semi-permanent hair dye with an electrifying bright yellow finish and a bold blacklight glow. Apply to pre-lightened hair for the brightest, most vibrant neon yellow result.
Vegan, cruelty-free and made in the Netherlands.
Description
Happy is made for bright yellow hair that brings instant energy. This highly pigmented UV-reactive shade gives an electrifying neon yellow result on light or pre-lightened hair and glows under blacklight.
For the most vivid result, we recommend applying Happy to pre-lightened hair. The colour gradually fades over time into softer pastel yellow tones, depending on your hair base, hair condition and aftercare routine.
Best results
For the brightest and most even result, apply Happy to very light blonde or pre-lightened hair.
Because Happy is a neon UV shade, it needs a light base to show its full colour intensity and blacklight effect. On darker hair, the colour may appear much less visible.
Always do a strand test before colouring to check how the shade turns out on your own hair.

How to use
1. Prep
For the brightest neon yellow result, pre-lighten your hair first with Attitude Ghosted Bleach.
2. Dye
Apply Happy evenly to clean, dry or towel-dried hair. Make sure the colour is fully worked through from roots to ends for an even result.
3. Rinse & care
Rinse until the water runs mostly clear. Keep your colour fresh for longer with colour-friendly aftercare, such as Holyplex Haircare.
Mix & match
Get creative with Happy. Mix it with Rebel for a glowing UV orange shade, or blend it with Toxic for a radioactive lime-green result.
Always test your mix on a strand first before applying it to your full head.
Good to know
Happy is a semi-permanent direct dye. The final result depends on your starting hair colour, porosity, hair condition and previous treatments.
UV shades perform best on very light or pre-lightened hair. For the best result, always do a patch test and strand test before colouring. Follow the instructions on the packaging carefully.
