Fluorescent Glow is an amazingly versatile colour and works brilliantly as a standalone colour or as a mixer to create brighter, glowing shades of turquoise, green, orange or red. Mix a dab of Flo Glow with a bright blue to create turquoise, add a bit more yellow to make a vibrant, glowing green or mix with small amount of bright pink to make orange or add more pink to create a really luminous red!

Like all yellows, this colour is only going to work well if your hair has been bleached to light blonde before application. It has a tendency to photograph with a green tint but this is not usually visible in person. Although if you have any leftover tint from your last colour then it will affect the colour result. It’s best to start with a base colour that’s as close to blonde as possible.

It glows light a highlighter pen under UV and is extremely bright in normal light. Fluorescent pigments can be difficult to remove (they don’t respond well to colour remover), so the best method for removing this colour is to let it wash out.

Check out the articles where we’ve used this colour to see just how bright it is, though it’s even brighter in real life!


Directions works best on hair that has been pre-lightened to pale blonde. Some paler shades as well as toners will only work on very light hair. Apply directly to dry or slightly damp, freshly washed (but not conditioned hair) using a tint brush for best results, or use gloved fingers to spread the dye evenly through your hair. Allow to process for at least 15 minutes and do not allow to dry out. Rinse thoroughly. To avoid temporary staining to the skin, apply a layer of Vaseline around your hairline and ears before applying the colour.
