Understanding the Color Wheel:
* Green's Opposite: The opposite of green on the color wheel is red. This is the key to neutralizing green tones.
Your Options:
1. Red/Red-Based Tones:
* Red Filler: This is the most reliable option, especially if you're going for a darker color afterwards. Apply a red color-depositing product (a "filler") to your hair. This adds the necessary red pigment to counteract the green.
* Red/Copper Direct Dye: Apply a red or copper direct dye (like Manic Panic, Arctic Fox, or similar). These dyes don't require developer and are less damaging. Leave on for a longer period than usual (following manufacturer's instructions).
* Strawberry Blonde/Auburn: If you want to go lighter, a strawberry blonde or light auburn shade might work *if* the green is very faded. You'll need to choose a shade with a strong red/copper base.
2. Darker Colors (Browns, Blacks):
* Red Undertones are Crucial: Even if you want brown or black, you'll still need to consider red undertones.
* Choose a Color with Red/Warm Undertones: When selecting your brown or black dye, look for options described as "warm brown," "chocolate brown," "auburn brown," "red-brown," or "black with red/violet undertones." Avoid cool or ashy browns, as they can make the green look muddy.
* Pre-Color with Red (Recommended): For the best results, apply a red filler or direct dye *before* applying the brown or black dye.
3. Neutralizing with a Tinted Shampoo or Conditioner:
* Red or Pink Shampoo/Conditioner:
These can help gradually neutralize the green. They work best on lighter greens or as a maintenance tool after using a stronger color correction method.
Steps to Take Before Dyeing:
1. Assess the Green:
* How intense is the green? A vibrant, dark green will be much harder to cover than a faded pastel green.
* What kind of dye was used? Direct dyes fade differently than permanent dyes.
2. Strand Test:
* Absolutely essential! Before applying any dye to your whole head, test it on a small, hidden section of your hair. This will show you how well the dye covers the green and what the final color will look like.
3. Consider Damage:
* Assess the health of your hair. If your hair is already damaged, multiple dyeing processes can cause further breakage. You may need to deep condition or protein treat your hair before and after dyeing.
Dyeing Process:
1. Apply Red Filler (if using): Follow the instructions on the red filler product.
2. Apply Target Color: Apply your chosen dye carefully, ensuring that all of the green is covered.
3. Process According to Instructions: Follow the manufacturer's instructions for processing time.
4. Rinse Thoroughly: Rinse the dye out completely.
5. Deep Condition: Replenish moisture lost during the dyeing process.
Important Considerations:
* Level of Expertise: If you're unsure about color correction, it's best to consult a professional hairstylist. They can assess your hair and recommend the best course of action. Color correction is complex, and DIY attempts can sometimes make the situation worse.
* Multiple Sessions: It may take multiple dyeing sessions to fully cover the green, especially if it's a very strong color. Be patient and avoid over-processing your hair.
* Developer Volume: If you're using a permanent dye, use a low-volume developer (10 or 20 volume) to minimize damage.
Example Scenarios:
* Light Pastel Green: A strawberry blonde dye with strong red/copper tones might be sufficient. A few washes with red color depositing shampoo would also help.
* Vibrant Dark Green: Red filler followed by a dark brown with red undertones is the most likely solution.
* Faded Emerald Green: A copper direct dye as a filler, followed by a brown with warm undertones.
In summary, covering green hair dye usually requires adding red tones. The exact method depends on the intensity of the green and your desired final color. Strand tests and careful consideration of your hair's health are essential.
