La Riche Directions Fluorescent Yellow is a semi-permanent hair dye in a fluorescent yellow that glows under blacklight. It only works on hair that is almost white. The color glows brightly under UV light or blacklight. You don't need a developer: simply apply the cream directly from the pot to your hair. It contains no ammonia or peroxide, so your hair is not opened up like with permanent dye.

The color attaches to the outside of your hair and gradually washes out over four to six weeks, depending on how often you wash it. This allows you to try Fluorescent Yellow without being stuck with it for months. The 100 ml pot is resealable, so you can store any leftovers for next time.

What hair it works on

This shade requires a very light base: platinum blonde or almost white bleached hair. On golden blonde hair, the color blends with the yellow undertone, and you will get a different result than shown on the pot. You will see very little of it on darker hair. If you want the color on darker hair, you must bleach it first.

How to use

1. Wash your hair with shampoo without conditioner and towel-dry it.
2. Apply some petroleum jelly to your hairline, ears, and neck to prevent the color from staining your skin.
3. Put on gloves and distribute the cream evenly from roots to ends. A dye brush helps with application.
4. Leave on for 15 to 30 minutes. Leaving it on longer will result in a more intense color.
5. Rinse out with cold water until the water is clear. Do not use shampoo afterwards.
6. Dry and style your hair as usual.

Do not mix Directions with peroxide. Always perform a strand test on a lock of hair first so you know exactly what color you will get.

Keeping the color beautiful for longer

Pastels fade faster than bright shades. Wash your hair with lukewarm to cool water and a mild sulfate-free shampoo. Between dye applications, you can mix a small amount into your conditioner; this will refresh the color with every wash.

Mixing with other colors

All Directions colors can be mixed together. Mix Fluorescent Yellow with Fluorescent Lime for a neon green-yellow, or with Fluorescent Orange for a warmer neon yellow. If you want a lighter, pastel version of Fluorescent Yellow, mix a small amount into a white conditioner.
