Achieving the perfect hair color is often a journey, and sometimes, that journey takes an unexpected turn – like winding up with green hair. Whether it’s a mishap with bleach, a reaction with pool chemicals, or just a funky interaction with your color, green tones can be frustrating. This leads to the burning question: Can purple shampoo, the holy grail for brassy blondes, come to the rescue when your hair resembles a mermaid gone wrong? Let’s dive deep into the science behind hair color, color correction, and the capabilities (and limitations) of purple shampoo.
Understanding Hair Color and the Color Wheel
Before we can tackle the green issue, it’s essential to understand the basics of hair color and how the color wheel plays a vital role in correction. Hair color is determined by pigments, primarily melanin (eumelanin for brown and black hair, pheomelanin for red and blonde hair). When you lighten your hair, you’re essentially removing these pigments.
The color wheel is a visual representation of colors arranged according to their chromatic relationship. Colors opposite each other on the wheel are called complementary colors. These colors neutralize each other when combined. In the case of hair color, this principle is fundamental to color correction.
Green and red are opposites on the color wheel. This means that red tones can neutralize green tones. Similarly, purple and yellow are opposites, which explains why purple shampoo is effective in neutralizing yellow brassiness in blonde hair.
The Culprits Behind Green Hair
So, how does hair turn green in the first place? There are several common culprits:
-
Chlorine: Perhaps the most well-known cause of green hair is chlorine in swimming pools. Chlorine itself doesn’t necessarily turn hair green. The problem arises when chlorine oxidizes metals, like copper, that are present in the water (often from pipes). These oxidized metals bind to the proteins in your hair, resulting in a greenish hue.
-
Hard Water: Hard water contains high levels of minerals like copper and iron. Over time, these minerals can deposit on the hair shaft, leading to a greenish or rusty discoloration.
-
Hair Dye Mishaps: Sometimes, a green tint can result from a chemical reaction during the hair dyeing process. This might occur if you mix different dyes or if the dye interacts poorly with your existing hair color or any pre-existing buildup on your hair.
-
Toners and Dyes with Blue Undertones: Certain toners or dyes contain a significant amount of blue pigment. If your hair is already very light or porous, it may absorb too much of the blue, resulting in a greenish-blue hue.
Purple Shampoo: How It Works (and When It Doesn’t)
Purple shampoo contains violet pigments designed to neutralize yellow tones in blonde, silver, or highlighted hair. It works by depositing these pigments onto the hair shaft. The purple pigments counteract the yellow, making the hair appear brighter and less brassy.
However, the key here is that purple shampoo targets yellow tones. While purple and green are both cool colors, they are not directly opposite each other on the color wheel. Therefore, purple shampoo is not designed to neutralize green tones.
Purple shampoo is effective for neutralizing yellow, but not green. It is not a one-size-fits-all solution for hair color correction.
Will Purple Shampoo Help Green Hair? Scenarios and Expectations
The effectiveness of purple shampoo on green hair depends on the specific shade and intensity of the green, as well as the underlying base color of your hair. Here are some scenarios:
-
Slightly Greenish Blonde Hair: If your blonde hair has only a very subtle greenish tint, purple shampoo might help slightly. It won’t directly cancel out the green, but it could brighten the overall tone and make the green less noticeable by counteracting any yellow undertones that might be exacerbating the green. However, don’t expect a dramatic transformation.
-
Clearly Green Hair: If your hair is distinctly green, purple shampoo will likely have little to no effect. The purple pigments are designed to counteract yellow, not green. Using purple shampoo on clearly green hair could even make the situation worse by adding a purplish undertone, creating an odd, muddy color.
-
Green Highlights or Lowlights: Similar to the above scenario, purple shampoo won’t specifically target green highlights. It will primarily affect the blonde or lightened portions of your hair, leaving the green untouched.
Effective Solutions for Correcting Green Hair
Since purple shampoo is unlikely to solve your green hair woes, what are the alternatives? The best approach depends on the cause of the green and the severity of the discoloration.
Clarifying Shampoo and Chelating Treatments
If the green tint is due to mineral buildup from hard water or chlorine, a clarifying shampoo or chelating treatment can be very effective.
-
Clarifying Shampoos: These shampoos are designed to remove product buildup, dirt, and excess oil from the hair. They can also help to lift mineral deposits, although they are not as powerful as chelating treatments.
-
Chelating Treatments: Chelating treatments contain ingredients that bind to metal ions (like copper and iron) and remove them from the hair. These treatments are specifically designed to address mineral buildup and are often the best solution for chlorine-induced green hair. Look for products containing EDTA or phytic acid.
Tomato Paste or Ketchup
Believe it or not, tomato paste or ketchup can be a surprisingly effective home remedy for green hair. This is because tomatoes contain a high concentration of red pigment, which, as we know from the color wheel, can neutralize green.
To use this method:
- Apply tomato paste or ketchup liberally to the affected areas of your hair.
- Leave it on for 20-30 minutes.
- Rinse thoroughly and shampoo as usual.
- You may need to repeat this process a few times to achieve the desired results.
The acidity of tomatoes can also help to remove mineral deposits.
Red-Toned Toners or Dyes
For more stubborn green tones, a red-toned toner or dye might be necessary. This approach involves adding red pigment to the hair to neutralize the green.
-
Toner: A toner is a semi-permanent color that helps to adjust the tone of the hair. Choose a red-toned toner specifically designed to counteract green.
-
Semi-Permanent Dye: If the green is very intense, you might need to use a semi-permanent red dye. Choose a shade that is slightly darker than the green in your hair.
Important: It’s always best to consult with a professional hairstylist before using toners or dyes, especially if you’re unsure about the process. They can help you choose the right product and application technique to avoid further damage or unwanted results.
Professional Color Correction
In severe cases of green hair, professional color correction is the best option. A skilled hairstylist has the knowledge and experience to assess the situation, determine the cause of the green, and formulate a customized solution. They can use a combination of techniques, including color stripping, toning, and dyeing, to restore your hair to its desired color.
Professional color correction is often the safest and most effective way to fix significant hair color problems.
Preventing Green Hair in the Future
Prevention is always better than cure. Here are some tips to help you avoid green hair in the first place:
-
Swim Smart: Before swimming in chlorinated water, wet your hair thoroughly with tap water. This will help to prevent your hair from absorbing as much chlorinated water. You can also apply a leave-in conditioner or hair oil to create a barrier. Wear a swimming cap to protect your hair. Rinse your hair immediately after swimming. Use a clarifying shampoo or chelating treatment regularly if you swim frequently.
-
Address Hard Water Issues: If you have hard water, consider installing a water softener in your home or using a shower filter to remove minerals. Use shampoos and conditioners specifically designed for hard water.
-
Be Careful with Hair Dyes: Always follow the instructions carefully when using hair dyes. Avoid mixing different dyes or using dyes that are known to react poorly with your hair. Do a strand test before applying the dye to your entire head.
-
Protect Your Hair from the Elements: Sun exposure can also contribute to color fading and discoloration. Use a heat protectant spray when using heat styling tools. Wear a hat or scarf to protect your hair from the sun.
Conclusion: Purple Shampoo Isn’t a Green Hair Miracle Worker
While purple shampoo is a fantastic tool for maintaining blonde and silver hair by neutralizing yellow tones, it’s not the solution for correcting green hair. Understanding the color wheel and the causes of green hair is crucial for choosing the right approach.
If you have a minor greenish tint, clarifying shampoos or home remedies like tomato paste might help. For more significant green discoloration, red-toned toners or dyes, or professional color correction, are the best options. By taking preventative measures, you can also minimize your risk of ending up with green hair in the first place. Remember, when it comes to hair color, knowledge is power, and a little research can save you a lot of frustration. Always consult a professional for complex color corrections.
Frequently Asked Questions
Can purple shampoo fix green hair?
Purple shampoo is specifically designed to neutralize yellow tones in blonde hair, helping to keep it bright and prevent brassiness. It works on the color theory principle that purple is opposite yellow on the color wheel, and therefore cancels it out.
Unfortunately, green and purple are not opposite colors on the color wheel. To neutralize green, you need to use a red-toned shampoo or toner. Purple shampoo will likely have little to no effect on green tones, and in some cases, could even make the green look more muted or dull.
Why does my hair turn green in the first place?
Green hair often results from swimming in chlorinated water. Chlorine can react with copper in pipes and pool water, depositing a green tint onto the hair, especially blonde or light-colored hair, which is more porous and absorbent. The copper binds to the hair proteins, causing the undesirable green hue.
Another less common cause could be from using hair products containing blue dyes, which, when mixed with existing yellow tones in the hair, can create a greenish cast. Additionally, some medications can rarely contribute to green discoloration of the hair.
What color neutralizes green in hair?
The color that neutralizes green tones in hair is red. Applying a red-toned color corrector or treatment will help to balance out the green and bring your hair back to a more natural shade. This is because red and green are complementary colors, meaning they sit opposite each other on the color wheel.
Red-based toners, shampoos, or glosses work by depositing red pigment into the hair shaft. The red pigment counteracts the green pigment, resulting in a more neutral brown or blonde shade, depending on your original hair color. The key is to use a product with the appropriate intensity of red to effectively neutralize the green.
How can I prevent my hair from turning green?
The most effective way to prevent green hair from chlorine exposure is to wet your hair with clean water before entering the pool. This saturates the hair, reducing its ability to absorb chlorinated water. Applying a leave-in conditioner or hair oil before swimming can also create a protective barrier.
Another preventative measure is to wear a swimming cap that fits snugly to minimize water exposure. After swimming, thoroughly rinse your hair with a chlorine-removing shampoo and follow with a deep conditioner to replenish moisture and remove any remaining chlorine or copper residue. Regular clarifying shampoos can also help prevent buildup.
What are some at-home remedies for removing green from hair?
One popular at-home remedy involves using ketchup. The red pigments in ketchup can help to neutralize the green tones. Apply ketchup to the affected areas, let it sit for 20-30 minutes, and then rinse thoroughly. You may need to repeat this process a few times.
Another option is to use a tomato juice rinse. Similar to ketchup, the red color in tomato juice can help to counteract the green. Apply tomato juice to your hair, leave it on for 15-20 minutes, and then rinse well. These remedies are generally mild and may require multiple applications for noticeable results.
When should I see a professional hair stylist to fix green hair?
If the green discoloration is severe, widespread, or persistent despite trying at-home remedies, it’s best to consult a professional hair stylist. They have the expertise and access to stronger, more effective color-correcting treatments and can accurately assess the condition of your hair.
A stylist can formulate a personalized solution based on the specific shade of green and the underlying color of your hair. Attempting to correct a difficult color issue yourself can potentially damage your hair or lead to further discoloration, so seeking professional help can save you time, money, and frustration in the long run.
Are there any shampoos besides purple shampoo that can help with color correction?
Yes, there are other color-depositing shampoos besides purple shampoo that can assist with color correction. Blue shampoo is used to counteract orange tones, while red shampoo is used to neutralize green tones as previously mentioned. These shampoos deposit small amounts of pigment with each wash.
Green shampoo is used to refresh red hair, and silver shampoo is used to neutralize yellow and brassy tones in gray or white hair. It’s important to understand the color theory behind each shampoo and choose the one that complements the unwanted tones in your hair for effective color correction. Using the wrong shampoo could exacerbate the problem.
