1. Make sure your hair is (lightly) bleached. The lighter, the brighter the result.
2. Wash your hair beforehand but skip conditioner. Conditioner smooths hair, making colour take less effectively.
3. Distribute dye evenly through your hair with a brush or your hands. Wear gloves, as the colour also stains skin.
4. Leave the dye on for at least thirty minutes. Longer gives a more intense colour.
5. Rinse with cold or lukewarm water until clear. Don't use shampoo when rinsing out.

Want to try or combine other neon colours? Directions Semi-PerManent Fluorescent Orange Color is a natural choice if you want to play with multiple bright shades or create gradient looks.

The bright yellow colour comes from BaSic Yellow 40, a fluorescent dye that reacts strongly to UV light. That’s exactly why your hair glows under blacklight. The formula also contains CeTearyl Alcohol, a fatty alcohol that keeps the cream soft and smooth. This makes application easy and leaves your hair feeling softer after dyeing.

Since it contains no ammonia or peroxide, this is a semi-perManent ammonia-free dye that’s gentler on your hair than regular peroxide dyes. The colour fades gradually over a few washes so you can easily refresh or change it. For those who want to shine at festivals, this neon yellow hair dye truly delivers.

No, not well. On dark blonde to black hair, the colour is hardly visible or appears as a dull yellow-green tint. For a truly bright result you need (lightly) bleached or platinum blonde hair. The whiter your hair, the closer you get to that marker-bright neon yellow. If your hair still has warm or yellow undertones after bleaching, the result might lean towards orange-yellow rather than pure neon.

Expect about four to eight washes before noticeable fading. Wash your hair with cold or lukewarm water and a mild shampoo without sulphates. The less you wash and the gentler you are, the longer the colour stays vibrant. When you want to refresh the colour, just apply another layer.

If you're wondering how long La Riche Directions Fluorescent Yellow lasts: it really depends on how you wash and care for your hair. With proper care, you can get about two weeks of wear.

Brands like Manic Panic Electric Banana and Crazy Color Toxic UV are in the same category. In brightness and UV response, La Riche Directions Semi-Permanent Fluorescent Yellow Color - 88ml matches those brands. The big advantage is price: for a small investment, you get a pot that can be used multiple times. Professional lines like Goldwell Elumen last longer but require salon expertise and cost more.
