Understanding color theory is essential when venturing into the world of hair coloring, especially when dealing with unwanted red tones. Red undertones can stubbornly appear after bleaching, dyeing, or even from sun exposure. Knowing which colors neutralize red is crucial to achieving your desired hair shade.
Understanding Red Undertones in Hair
Before diving into color correction, it’s important to understand why red tones appear in the first place. Natural hair color is determined by two types of melanin: eumelanin (which produces brown and black pigments) and pheomelanin (responsible for red and yellow pigments).
When you lighten your hair, you’re essentially breaking down these melanin molecules. Eumelanin is typically easier to break down than pheomelanin. This means that during the lightening process, the brown and black pigments are often removed first, leaving behind the more resistant red and orange pigments.
Factors such as your natural hair color, the strength of the developer used, and the amount of time the lightener is left on your hair all play a role in the intensity of the remaining red tones. Even naturally dark hair can reveal significant red undertones when lightened.
Certain dyes can also deposit red pigments into the hair shaft. Repeated use of these dyes can lead to a build-up of red tones, making them harder to neutralize. Even environmental factors like sun exposure can contribute to the development of red or brassy tones.
The Color Wheel and Complementary Colors
The key to neutralizing red lies in understanding the color wheel. This tool visually represents the relationship between different colors and helps identify complementary colors – colors that sit opposite each other on the wheel. When placed together, complementary colors cancel each other out, creating a neutral tone.
In the case of red, its complementary color is green. This means that applying a green-toned hair color can effectively neutralize unwanted red undertones. However, it’s not as simple as just slapping on green dye. The specific shade of green and the intensity of the red undertones both need to be considered for optimal results.
Choosing the Right Green-Toned Hair Color
Selecting the appropriate green-toned hair color depends on several factors, including the intensity of the red and your desired end result.
Assessing the Red Intensity
Before choosing a green-toned color, carefully assess the intensity of the red in your hair. Is it a vibrant, fiery red, or a more subtle, coppery hue? The intensity of the red will determine the strength of the green needed to neutralize it.
For vibrant, intense red tones, you’ll need a stronger green-toned color. This might involve using a hair dye specifically formulated for color correction or adding a green color additive to your existing dye.
For more subtle, coppery red tones, a gentler green-toned color will suffice. This could involve using an ash blonde or cool brown dye that contains subtle green undertones.
Understanding Hair Levels
Hair color is typically categorized into levels, ranging from 1 (black) to 10 (lightest blonde). Understanding your current hair level is crucial for choosing the right green-toned color.
If your hair is dark (levels 1-5) and has red undertones, you may need to lighten it further before applying a green-toned color. However, be cautious about over-lightening, as this can damage your hair.
If your hair is already light (levels 6-10) and has red undertones, you can typically apply a green-toned color directly. However, it’s important to choose a shade that is close to your desired end result to avoid unwanted green hues.
Types of Green-Toned Hair Colors
There are several types of green-toned hair colors available, each with its own advantages and disadvantages.
Ash Blonde/Brown Dyes: These dyes contain subtle green undertones that can help neutralize mild red tones. They are a good option for those who want to achieve a cool, neutral blonde or brown shade.
Color Correcting Dyes: These dyes are specifically formulated to neutralize unwanted undertones, including red. They typically contain a higher concentration of green pigment and are a good option for those with more intense red tones.
Green Color Additives: These additives can be added to your existing hair dye to create a custom green-toned color. They allow for greater control over the amount of green pigment and are a good option for those who want to fine-tune their color correction.
Toners: Toners are demi-permanent hair colors that deposit tone without lifting the base color. Green toners are an excellent option for neutralizing red tones on pre-lightened hair. They are gentler than permanent dyes and help maintain the health of your hair.
Application Techniques for Neutralizing Red
The application technique is just as important as choosing the right color. Proper application ensures even coverage and prevents unwanted green hues.
Strand Test
Before applying any green-toned color to your entire head, it’s crucial to perform a strand test. This involves applying the color to a small, hidden section of your hair to see how it reacts. This will help you determine if the color is effective at neutralizing the red and if it will achieve your desired end result.
Even Application
When applying the green-toned color, ensure even coverage. This is particularly important when using a stronger green-toned color, as uneven application can result in patchy green hues. Use a tint brush to apply the color section by section, ensuring that every strand is coated.
Processing Time
Follow the manufacturer’s instructions for processing time. Over-processing can result in unwanted green hues, while under-processing may not effectively neutralize the red. Regularly check the color during processing to ensure that it is achieving the desired result.
Rinsing and Conditioning
After processing, rinse your hair thoroughly with cool water. This helps to seal the cuticle and prevent further color fading. Follow with a moisturizing conditioner to replenish any lost moisture.
Maintaining Your Color and Preventing Red Tones
Once you’ve successfully neutralized the red in your hair, it’s important to maintain your color and prevent it from returning.
Use Color-Safe Shampoo and Conditioner
Use shampoos and conditioners specifically formulated for color-treated hair. These products are designed to be gentle on the hair and help prevent color fading. Avoid using harsh sulfates, which can strip the color from your hair.
Avoid Heat Styling
Excessive heat styling can damage your hair and cause color to fade. Minimize your use of heat styling tools such as blow dryers, curling irons, and straighteners. When you do use heat styling tools, use a heat protectant spray to shield your hair from damage.
Protect Your Hair from the Sun
Sun exposure can cause hair color to fade and develop unwanted red or brassy tones. Wear a hat or scarf when spending extended periods of time in the sun. You can also use hair products that contain UV filters.
Use a Toner Regularly
To maintain the cool tones in your hair, use a green-based toner regularly. This will help to counteract any red tones that may develop over time.
Professional Touch-Ups
Consider visiting a professional hair stylist for regular touch-ups. A stylist can help you maintain your color and prevent red tones from returning. They can also provide personalized advice on how to care for your hair.
Addressing Common Concerns
Neutralizing red tones can sometimes be tricky, and it’s normal to have concerns.
What if My Hair Turns Green?
This is a common fear! If your hair turns green, it usually means you’ve used a green-toned color that was too strong or left it on for too long. To correct this, you can use a clarifying shampoo to help strip some of the green pigment. You can also try using a red-toned toner to counteract the green. In severe cases, you may need to consult a professional stylist.
Can I Use Purple Shampoo to Neutralize Red?
Purple shampoo is designed to neutralize yellow tones, not red. While it might slightly reduce brassiness, it won’t effectively cancel out red undertones.
My Hair is Dark. Will Green Still Work?
For dark hair with red undertones, you might need to lighten it first. However, be careful not to over-lighten, as this can damage your hair. A color-correcting dye or a green-toned additive to your dye might be a better option than just a standard ash dye.
Is It Always Necessary to Use a Green-Toned Dye?
Not necessarily. Sometimes, a cool-toned ash blonde or brown dye can be enough to neutralize mild red tones. It depends on the intensity of the red and your desired end result.
Conclusion
Neutralizing red tones in hair requires a good understanding of color theory and careful execution. By choosing the right green-toned hair color, applying it properly, and maintaining your color with proper care, you can achieve your desired shade and say goodbye to unwanted red undertones. Remember to perform a strand test, prioritize the health of your hair, and consider consulting a professional stylist for best results. With the right approach, achieving your dream hair color is within reach.
What color neutralizes red tones in hair?
The color that neutralizes red tones in hair is green. Green sits directly opposite red on the color wheel, making it its complementary color. This means that when you combine green and red, they effectively cancel each other out, resulting in a more neutral tone.
Therefore, if you’re aiming to counteract red tones in your hair, you’ll want to look for products with a green base. These can include green-toned shampoos, conditioners, or even toners designed to neutralize unwanted red hues. Understanding this color theory is crucial for achieving your desired hair color outcome.
Why does my hair turn red after coloring?
Hair turns red after coloring for a few primary reasons, often related to the underlying pigments in your hair and the chemicals used during the coloring process. Natural hair color is composed of varying amounts of red, yellow, and blue pigments. When you lighten your hair, the blue pigments are typically the first to be lifted, followed by the yellow, leaving the red pigments behind.
The artificial pigments deposited during the coloring process can also fade, revealing these underlying red tones. This is especially common if you are trying to go significantly lighter than your natural color. The red pigments are incredibly stubborn and require specific strategies to effectively neutralize or cover them during the coloring process.
How do I choose the right green-based product for my hair?
Choosing the right green-based product depends on the intensity of the red tones you’re trying to neutralize and your current hair color. For slight red tones, a green-toned shampoo or conditioner might suffice. These products deposit a small amount of green pigment with each use, gradually neutralizing the red over time.
If you have strong red tones or are looking for a more immediate solution, a green-based toner is the better choice. Toners are stronger than shampoos and conditioners and will provide a more significant color correction. However, toners should be used carefully and according to the manufacturer’s instructions to avoid over-toning and potentially turning your hair green. It’s often best to consult a professional colorist.
Can I use a box dye to cancel out red in my hair?
While technically possible, using a box dye to cancel out red in your hair is not generally recommended, especially if you lack experience with color correction. Box dyes are formulated for general use and don’t always account for the unique nuances of your hair’s underlying pigments. Choosing the wrong shade or strength can result in uneven color, damage, or even further accentuate the red tones.
It’s much safer and more effective to consult a professional hairstylist who can assess your hair’s current condition and recommend a personalized color correction plan. They’ll be able to choose the right products and techniques to neutralize the red without causing unnecessary damage. Professional color correction often involves precise mixing of pigments and careful application, which is difficult to replicate at home with box dye.
What are some alternative methods for reducing red tones in hair?
Besides green-based products, several alternative methods can help reduce red tones in hair. A semi-permanent color with cool undertones like ash or blue can help to tone down the red without significantly altering your base color. It’s crucial to select a shade that’s close to your current hair color to avoid unwanted results.
Another method is to use a color depositing mask with blue or purple pigments. These masks are less intense than toners but can gradually neutralize red tones with repeated use. Regularly using a clarifying shampoo can also help to remove buildup that might be contributing to the reddish appearance. Consider consulting a hair stylist to determine the best and safest approach for your specific situation.
How often should I use a green-toned shampoo or conditioner?
The frequency of using a green-toned shampoo or conditioner depends on the severity of the red tones in your hair and how quickly your hair absorbs pigment. For subtle red tones, using it once or twice a week may be sufficient. Observe your hair’s color closely after each use to determine if the product is effectively neutralizing the red.
If you have more prominent red tones, you might need to use the product more frequently, perhaps every other wash. Pay close attention to how your hair responds and adjust the frequency accordingly. Overuse can potentially lead to a slight greenish tint, especially on lighter hair, so moderation is key. Always follow the product instructions and discontinue use if you notice any undesirable color changes.
How do I prevent my hair from turning red after coloring?
Preventing your hair from turning red after coloring starts with choosing the right hair color and understanding your hair’s underlying pigments. If you’re aiming for a lighter shade than your natural color, consider gradually lifting the color over multiple sessions to minimize the exposure of underlying red pigments. Use a color-safe shampoo and conditioner to prolong the life of your color and prevent fading, which can reveal red tones.
Regularly using a color depositing conditioner with blue or purple pigments can also help maintain a cool tone and prevent the red from resurfacing. Avoid excessive heat styling, as heat can cause the artificial pigments to fade faster. Finally, consider consulting a professional stylist for color maintenance and touch-ups to ensure the underlying red tones are properly addressed with each coloring session.
