Getting rid of unwanted green tones in your hair can be a frustrating experience, but understanding color theory and the right techniques can help you achieve your desired hair color. Green hair can be caused by a variety of factors, and knowing how to neutralize it is essential for maintaining beautiful and healthy locks.
Understanding Why Hair Turns Green
Before diving into the color correctors, it’s crucial to understand why hair might develop green tones in the first place. Several common culprits contribute to this unwanted effect.
Chlorine Exposure
One of the most frequent reasons for green hair, especially for those with lighter shades like blonde or platinum, is exposure to chlorine in swimming pools. Chlorine is a chemical disinfectant that, over time, can bind to the hair shaft. The copper in chlorine is what often causes the green discoloration.
Mineral Buildup
Hard water, which is rich in minerals like copper and iron, can also lead to green tints. These minerals can deposit onto the hair over time, especially if you use certain shampoos or conditioners that don’t effectively remove them. Copper piping in older homes can exacerbate this issue.
Dyeing Over Lightened Hair
Applying darker dyes over lightened hair can sometimes result in green undertones. This is particularly true if the underlying yellow tones in the lightened hair aren’t properly neutralized before applying the new color. These underlying tones interact with the dye to create an undesirable green hue.
Certain Hair Products
Some hair products may contain ingredients that react with the hair, causing a green cast. This is rarer than the other causes but still worth considering if you can’t pinpoint another reason for the green tinge.
The Magic of Color Theory: Correcting Green
Color theory is your best friend when it comes to neutralizing unwanted tones. Understanding the color wheel is essential.
Identifying Complementary Colors
The key principle here is complementary colors. Complementary colors are located opposite each other on the color wheel. For green, its complementary color is red. This means that adding red tones will effectively neutralize and counteract the green hue in your hair.
Understanding Undertones
Not all reds are created equal. The specific type of red needed to correct green depends on the specific shade of green you are trying to neutralize. A cooler, ashier green might require a warmer, more vibrant red, while a warmer, more yellow-toned green might benefit from a cooler, more violet-red.
Methods for Toning Out Green Hair
Now that you understand the theory, let’s explore the practical methods you can use to banish those green tones.
Using Red-Toned Shampoos and Conditioners
One of the easiest methods for subtly correcting green tones is using a red-toned shampoo or conditioner. These products deposit a small amount of red pigment onto the hair with each wash, gradually neutralizing the green. They’re best suited for minor green discoloration and preventative maintenance. Remember to use these products sparingly at first, as overusing them can lead to a reddish tint in your hair.
Direct Dyes
For more significant green discoloration, a direct dye with red or reddish-orange tones might be necessary. These dyes are applied directly to the hair without mixing with a developer, making them a gentler option than permanent dyes.
- Choose a shade carefully based on the type of green you’re dealing with.
- Apply the dye evenly, focusing on the areas with the most green.
- Follow the product instructions carefully regarding processing time and rinsing.
Professional Color Correction
If you’re unsure about tackling the color correction yourself, or if the green discoloration is severe or uneven, it’s best to consult a professional hair colorist. They have the expertise to assess the situation accurately and formulate a custom color correction plan that will minimize damage and achieve the desired results.
Tomato Ketchup or Tomato Paste Mask
This may sound strange, but the red pigment in tomato ketchup or tomato paste can help neutralize green tones. This is a natural and gentle option, but it might not be as effective for severe cases of green hair.
- Apply the ketchup or paste liberally to the affected areas.
- Leave it on for 20-30 minutes.
- Rinse thoroughly and follow with your regular shampoo and conditioner.
DIY Hair Masks
You can create DIY hair masks with ingredients that have a slight red tint. Beet juice, cranberry juice, and paprika can all be mixed with a hair-friendly base like coconut oil or yogurt to create a mask. These methods are very gentle and might require multiple applications.
Preventing Green Hair in the First Place
Prevention is always better than cure. Taking proactive steps can significantly reduce the risk of your hair turning green.
Swimming Precautions
If you’re a frequent swimmer, take these precautions:
- Wet your hair thoroughly with tap water before entering the pool. This will help prevent your hair from absorbing as much chlorinated water.
- Apply a leave-in conditioner or hair oil to create a barrier.
- Wear a swimming cap to protect your hair from direct exposure to chlorine.
- Rinse your hair immediately after swimming with a chlorine-removing shampoo.
Using Filtered Water
If you live in an area with hard water, consider using a shower filter to remove minerals that can cause green buildup. You can also use distilled water to wash your hair for the same effect, though this is not always practical.
Clarifying Shampoos
Use a clarifying shampoo regularly to remove mineral buildup and product residue. However, be careful not to overuse clarifying shampoos, as they can be drying.
Proper Toning After Bleaching
If you’re bleaching your hair, make sure to tone it properly afterwards. Toning neutralizes any unwanted yellow or orange tones, creating a clean base for your desired color and minimizing the risk of green undertones in the future.
Product Recommendations
Choosing the right products can make a significant difference in your success in toning out green hair.
Red-Toned Shampoos
Several red-toned shampoos are available on the market. Look for ones specifically formulated for color-treated hair. Read reviews and choose one based on your hair type and the severity of the green discoloration.
Direct Dyes
When choosing a direct dye, opt for reputable brands that offer a wide range of red and reddish-orange shades. Consider a strand test before applying the dye to your entire head to ensure you achieve the desired result.
Clarifying Shampoos
Choose clarifying shampoos that are sulfate-free to minimize dryness. Many brands offer formulations designed to remove mineral buildup without stripping the hair of its natural oils.
Important Considerations
Before embarking on your color correction journey, keep these crucial points in mind.
Hair Porosity
Hair porosity refers to how well your hair absorbs and retains moisture. High porosity hair absorbs color quickly, while low porosity hair is more resistant. Understanding your hair’s porosity will help you determine the appropriate processing time and strength of the products you use.
Hair Condition
If your hair is already damaged, bleaching or using harsh chemicals can further exacerbate the problem. Prioritize repairing and strengthening your hair with protein treatments and deep conditioning masks before attempting any color correction.
Strand Test
Always perform a strand test before applying any dye or toner to your entire head. This will allow you to see how the product reacts with your hair and adjust the application accordingly.
Patience
Color correction is often a process that requires patience. It may take multiple attempts to achieve the desired results, especially if the green discoloration is severe.
When to See a Professional
While DIY methods can be effective for minor green tones, certain situations warrant professional help.
- Severe Discoloration: If your hair is significantly green, a professional colorist can assess the situation and formulate a targeted plan.
- Uneven Color: If the green tones are uneven, a professional can ensure an even application and prevent further damage.
- Damaged Hair: If your hair is already damaged, attempting DIY color correction can worsen the problem. A professional can use gentle techniques to minimize damage.
- Unsurety: If you’re unsure about which products to use or how to apply them, consulting a professional can save you time, money, and potential hair disasters.
Correcting green hair can seem daunting, but with the right knowledge and tools, you can restore your hair to its desired color. Understanding the causes of green hair, the principles of color theory, and the various correction methods is key to success. Whether you choose to try a DIY method or seek professional help, remember to prioritize the health of your hair and proceed with caution.
By understanding these nuances, you’ll be well-equipped to combat unwanted green tones and maintain beautiful, healthy hair.
Why does hair sometimes turn green after dyeing?
Chlorine in swimming pools is a common culprit behind green hair, particularly for those with blonde or lighter hair. Chlorine reacts with copper found in pool water and deposits it onto the hair shaft. This copper deposit, when combined with light-colored hair, results in a greenish hue.
Other factors can contribute to green hair as well. Certain medications, hard water with high mineral content (especially copper), and even some hair products containing dyes or metallic salts can cause a greenish tint over time. Identifying the source of the green discoloration is the first step towards effectively toning it out.
What color cancels out green in hair color theory?
According to the color wheel, red is the color that neutralizes green. This is because red and green are complementary colors, meaning they sit directly opposite each other on the color wheel. When mixed together, they cancel each other out, resulting in a neutral tone.
Using a red-toned shampoo, conditioner, or hair gloss can effectively counteract the green tones in your hair. The intensity of the red needed will depend on the severity of the green. Remember, applying pure red dye is often too intense and can lead to unwanted red tones in your hair; a diluted or specially formulated product is key.
Can I use tomato juice to remove green from hair?
Tomato juice is a popular home remedy for neutralizing green hair due to its natural red pigment. The acidity of the tomato juice can also help to lift the minerals causing the green discoloration from the hair shaft. While it may sound unconventional, many people have reported success with this method.
To use tomato juice, saturate your hair with it and let it sit for 20-30 minutes before rinsing thoroughly. Follow up with a moisturizing conditioner as the acidity can be drying. This method is generally considered gentle and safe for most hair types, but its effectiveness may vary depending on the intensity of the green tones.
What’s the best professional toning solution for green hair?
A professional stylist has access to a range of toners specifically designed to neutralize unwanted green tones. These toners often contain a violet-red base, which effectively cancels out the green and brings the hair back to a more neutral or desired shade. A professional can also assess your hair’s condition and choose the appropriate volume developer to minimize damage.
The stylist will carefully apply the toner, monitoring the process to achieve the desired result without over-toning or damaging the hair. Professional toners are formulated to be precise and predictable, reducing the risk of ending up with an undesirable color. They can also provide aftercare advice to help maintain the color and prevent future green discoloration.
How do I prevent my hair from turning green in the first place?
Protecting your hair before exposure to chlorine is crucial in preventing green discoloration. Wetting your hair thoroughly with clean water before swimming minimizes the amount of chlorinated water your hair can absorb. Applying a leave-in conditioner or hair oil can also create a protective barrier.
Wearing a swimming cap is the most effective way to shield your hair from chlorine. Additionally, rinsing your hair immediately after swimming with a clarifying shampoo can help remove any chlorine and copper deposits before they have a chance to cause discoloration. Consider investing in a shower filter if you have hard water.
What red-toned shampoos are recommended for toning out green?
Several red-toned shampoos are available that can help neutralize green hues. Look for shampoos specifically formulated for redheads or those designed to enhance warm tones. These shampoos contain red pigments that deposit onto the hair, counteracting the green.
Be cautious when using red-toned shampoos, as overuse can lead to a reddish tint in your hair. Start by using it once a week and adjust the frequency based on your hair’s needs and the severity of the green discoloration. Always follow with a moisturizing conditioner to prevent dryness.
What if my hair is already damaged; can I still tone out the green?
Damaged hair is more porous and susceptible to absorbing color unevenly. Toning green hair that is already damaged requires extra caution. It is best to consult with a professional stylist who can assess the damage and choose the appropriate toning method and products.
A gentler approach is often necessary, such as using a diluted toner or a color-depositing conditioner with red tones. Deep conditioning treatments before and after toning can help to minimize further damage and restore moisture. Avoid using harsh chemicals or over-processing the hair, as this can exacerbate the damage and lead to breakage.
