What Color Covers Green Hair? How to Hide or Neutralize Green Hair Dye

Have you ever dyed your hair a bold emerald green, only to later wish you could go back to your natural color? Or maybe you bleached your blonde hair and were shocked when it turned green instead!

Green hair can be a fun and adventurous look for a while. But eventually, there comes a time when you’re over the green and want to get back to your roots.

So what color covers green hair best? The good news is you can disguise green hues by using strategic hair dye colors, without having to strip out the green completely.

In this guide, we’ll explain what color cancels out green based on color theory. We’ll also recommend the best products to use, plus tips for protecting your hair during the process.

What Color Neutralizes Green Hair Pigment?

To understand how to cover up green hair, you first need to grasp some basic color theory.

The key is to use a shade that’s directly across from green on the color wheel. Opposite colors counterbalance each other.

Warm red and orange tones cancel out the cool green and blue undertones. Here are a few red/orange options that hide green hair:

• Red hair dye
• Orange hair dye
• Copper hair dye
• Red-orange shampoos
• Red/orange food coloring

Applying any of these warm-toned products to your hair will effectively neutralize the green molecules, allowing you to shift your color to something less cool-toned.

How to dye over green:

• Choose a red shade that matches your current level of green.
• Mix and apply the red dye following instructions.
• Leave on for 15-30 minutes, checking often.
• Rinse thoroughly until water runs clear.

Red dye will give you instant results, but beware of leaving it on too long, or your hair could end up literally red. Do a strand test first.
