Bleaching your hair is a transformative process. It lifts the natural pigment, providing a blank canvas for vibrant colors. But what happens when you actually apply hair dye to that freshly bleached canvas? The answer is complex and depends on several factors, ranging from the condition of your hair to the type of dye you use. Let’s delve into the intricacies of dyeing bleached hair and explore what you need to know to achieve the best possible results.
Understanding the Bleaching Process
Before we dive into the dye, let’s understand what bleaching does to your hair. Bleach, typically a combination of hydrogen peroxide and ammonia, opens the hair cuticle – the protective outer layer. This allows the bleaching agents to penetrate the hair shaft and dissolve the natural melanin, which gives your hair its color.
The more melanin that is dissolved, the lighter your hair becomes. However, this process is inherently damaging. It weakens the hair structure, making it more porous and prone to breakage. Over-bleaching can lead to brittle, dry, and even gummy hair. This is why it’s crucial to proceed with caution and understand the implications before reaching for the bleach.
The Porosity Factor
Bleaching significantly increases the porosity of your hair. Porosity refers to the hair’s ability to absorb and retain moisture. Highly porous hair has a raised cuticle, allowing moisture to enter quickly but also escape just as easily.
Bleached hair, being highly porous, soaks up hair dye like a sponge. This can be both a blessing and a curse. On the one hand, the color can take easily and result in a vibrant, intense hue. On the other hand, it can also lead to uneven color distribution and fading. This is why pre-treating bleached hair to balance its porosity is often recommended.
Dyeing Bleached Hair: Potential Outcomes
The outcome of dyeing bleached hair is heavily influenced by the dye’s characteristics and the underlying condition of the bleached hair. Let’s examine various scenarios.
Vibrant and True-to-Tone Color
When bleached hair is in relatively good condition and the right dye is used, you can achieve stunning, vibrant results that accurately reflect the color on the dye box. This is the ideal scenario, where the dye evenly penetrates the porous hair shaft, resulting in a rich, long-lasting color. Semi-permanent and demi-permanent dyes often work well on properly prepared bleached hair.
Uneven Color Distribution
Due to varying levels of porosity across the hair, the dye might be absorbed unevenly. This can result in patchy color, with some areas appearing darker or more intense than others. Hair that has been previously bleached or damaged is more likely to exhibit uneven color absorption. Proper preparation and application techniques are crucial to minimize this risk.
Color Fading
Bleached hair, with its increased porosity, tends to lose color more quickly than unbleached hair. The dye molecules, unable to fully grip the damaged hair shaft, wash out more easily with each shampoo. Using color-safe shampoos and conditioners, avoiding excessive washing, and minimizing heat styling can help prolong the color’s vibrancy.
Unexpected Tones
The underlying tone of your bleached hair can significantly impact the final color result. If your hair hasn’t been bleached to a completely neutral blonde (often a pale yellow), the remaining pigments can interact with the dye, resulting in unexpected tones.
For instance, applying a cool-toned blue dye to hair with yellow undertones could result in a greenish hue. This is why toning the hair after bleaching is often necessary to neutralize unwanted tones before applying the desired color.
Damage and Breakage
If your bleached hair is already compromised, dyeing it can further exacerbate the damage. The chemicals in the dye, even those designed for damaged hair, can weaken the hair structure, leading to increased breakage and split ends. Protein treatments and deep conditioning masks can help strengthen and hydrate the hair before and after dyeing.
Choosing the Right Hair Dye
Selecting the appropriate hair dye is paramount for achieving desired results and minimizing potential damage. Here’s a breakdown of different types of hair dye and their suitability for bleached hair.
Semi-Permanent Dyes
Semi-permanent dyes deposit color on the surface of the hair shaft without penetrating deeply. They are generally less damaging than permanent dyes and are a good option for adding a temporary tint or refreshing existing color.
Semi-permanent dyes are ideal for bleached hair that is already quite light, as they won’t lighten the hair further. These dyes are best for achieving pastel shades or adding vibrancy to already light blonde hair. Because they coat the hair rather than penetrating it, they tend to fade relatively quickly.
Demi-Permanent Dyes
Demi-permanent dyes contain a low-volume developer that allows the color to penetrate the hair shaft slightly. They provide more lasting color than semi-permanent dyes and can also blend away grays.
Demi-permanent dyes are a good choice for adding depth and dimension to bleached hair or for correcting unwanted tones. They are less damaging than permanent dyes but can still cause some dryness. They are excellent for depositing color and adding shine to porous bleached hair.
Permanent Dyes
Permanent dyes contain ammonia and a higher-volume developer, which allows the color to deeply penetrate the hair shaft and permanently alter its color. They offer the most long-lasting results and can lighten the hair.
However, permanent dyes are also the most damaging option and should be used with caution on bleached hair. They are generally not recommended for heavily processed or damaged bleached hair, as they can cause further breakage and dryness. If used, it’s crucial to choose a dye specifically formulated for damaged hair and to follow the instructions carefully.
Direct Dyes (Vibrant Colors)
Direct dyes, often used for vibrant colors like pink, blue, and green, don’t require a developer. They are applied directly to the hair and deposit color on the surface.
These dyes are generally less damaging than dyes that require a developer, making them a good option for bleached hair. However, they can fade quickly, especially on highly porous hair. They are ideal for achieving bold, fashion-forward colors on pre-lightened hair.
Preparing Bleached Hair for Dyeing
Proper preparation is key to ensuring successful and damage-free dyeing. Here are some essential steps to take before applying dye to bleached hair.
Assess Hair Condition
Before anything else, carefully assess the condition of your hair. Is it dry, brittle, or prone to breakage? If so, you need to focus on restoring its health before dyeing.
Deep conditioning treatments, protein masks, and hair oils can help strengthen and hydrate damaged bleached hair. Avoid dyeing if your hair is severely damaged, as it could lead to further breakage.
Perform a Strand Test
Always perform a strand test before applying dye to your entire head of hair. This will allow you to see how the color will look on your hair and whether it will cause any adverse reactions.
Select a small, inconspicuous section of hair and apply the dye according to the instructions. Leave it on for the recommended time, then rinse and dry. The strand test will help you determine if the color is what you want and if the dye is compatible with your hair.
Balance Porosity
As mentioned earlier, bleached hair is often highly porous, which can lead to uneven color absorption. To balance porosity, use a protein filler or a porosity control spray before dyeing.
These products help fill in the gaps in the hair shaft, creating a more even surface for the dye to adhere to. Balancing porosity ensures that the dye is absorbed evenly, resulting in a more uniform color.
Cleanse Hair Properly
Wash your hair with a clarifying shampoo a day or two before dyeing to remove any buildup of product or oils. Avoid using conditioner, as it can create a barrier that prevents the dye from penetrating the hair shaft.
Clean, product-free hair allows the dye to adhere properly, resulting in better color saturation.
The Dyeing Process: Step-by-Step
Once your hair is prepared, you’re ready to begin the dyeing process.
-
Protect Yourself: Wear gloves and an old t-shirt to protect your skin and clothing from staining.
-
Prepare the Dye: Mix the dye according to the instructions on the package.
-
Apply the Dye: Use a brush or applicator bottle to apply the dye evenly to your hair, starting at the roots. Work your way down to the ends, ensuring that all strands are thoroughly saturated.
-

Post-Dye Care for Bleached Hair
Caring for your hair after dyeing is crucial for maintaining the color’s vibrancy and preventing damage.
Use Color-Safe Shampoo and Conditioner
Color-safe shampoos and conditioners are formulated to be gentle on dyed hair and help prevent color fading. Avoid using shampoos that contain sulfates, as they can strip the color from your hair.
Look for products that are specifically designed for color-treated hair and that contain moisturizing ingredients.
Avoid Excessive Washing
Washing your hair too frequently can cause the color to fade more quickly. Try to limit washing to two or three times per week.
When you do wash your hair, use cool water, as hot water can open the hair cuticle and cause the color to leach out.
Protect from Heat
Heat styling tools, such as flat irons and curling irons, can damage dyed hair and cause the color to fade. Use a heat protectant spray before using any heat styling tools.
Consider air-drying your hair whenever possible to minimize heat damage.
Deep Condition Regularly
Deep conditioning treatments can help restore moisture and repair damage to dyed bleached hair. Use a deep conditioner or hair mask at least once a week.
Look for products that contain moisturizing ingredients, such as shea butter, coconut oil, or argan oil.
Avoid Sun Exposure
Prolonged exposure to the sun can cause hair color to fade and can also damage the hair. Wear a hat or scarf when you’re spending time outdoors to protect your hair from the sun’s harmful rays.
Dealing with Unwanted Tones
Sometimes, despite your best efforts, you might end up with unwanted tones in your hair after dyeing.
Toning
Toning can neutralize unwanted tones and create a more balanced color. For example, a purple shampoo or toner can neutralize yellow tones in blonde hair, while a green toner can neutralize red tones.
Use a toner that is specifically designed for your hair color and follow the instructions carefully.
Color Correction
If you’re dealing with a more significant color issue, you might need to seek professional help from a colorist. A colorist can assess your hair and recommend the best course of action to correct the color.
Attempting to correct a complex color issue on your own can often lead to further damage.
The Bottom Line
Dyeing bleached hair can be a rewarding experience, allowing you to experiment with different colors and express your personal style. However, it’s important to understand the potential risks and take the necessary precautions to protect your hair. By choosing the right dye, preparing your hair properly, and following a good aftercare routine, you can achieve stunning results while minimizing damage. Remember to prioritize the health of your hair and consult with a professional if you have any concerns.
What are the biggest risks of dyeing bleached hair?
Dyeing bleached hair carries several potential risks, primarily due to the porous and weakened state of the hair shaft. Bleaching processes strip the hair of its natural oils and proteins, making it more susceptible to damage when exposed to further chemical treatments. This increased porosity means the hair absorbs dye quickly, potentially leading to unpredictable or uneven color results. Overlap during dye application on previously bleached sections can also cause breakage and further damage, leading to brittle, straw-like texture.
Another significant risk is the potential for allergic reactions or scalp irritation. Bleached hair has a more sensitive scalp due to the chemical process. The chemicals in hair dye, particularly those containing ammonia or peroxide, can exacerbate this sensitivity, leading to redness, itching, and even burning. Furthermore, the weakened hair structure makes it prone to dryness and frizz, necessitating intensive conditioning and ongoing maintenance.
How long should I wait to dye my hair after bleaching it?
Waiting before dyeing bleached hair is crucial for the health and integrity of your strands. Ideally, you should wait at least two weeks between bleaching and dyeing your hair. This allows your hair’s cuticle to partially recover and rebuild some of the proteins lost during the bleaching process. Applying dye too soon after bleaching can result in further damage, uneven color absorption, and increased sensitivity of the scalp.
Furthermore, it gives you time to focus on deep conditioning treatments and strengthening the hair. Utilize protein-rich masks and moisturizing conditioners to replenish lost moisture and fortify the hair shaft. Observing your hair’s condition closely during this waiting period helps determine if it’s ready for another chemical process. If your hair feels brittle or excessively dry, extend the waiting period and continue intensive conditioning.
What type of dye is best for bleached hair?
Demi-permanent or semi-permanent hair dyes are generally the best choice for bleached hair. These dyes deposit color onto the hair shaft rather than penetrating deeply, which is gentler on already compromised strands. They also lack ammonia and peroxide, reducing the risk of further damage and scalp irritation. These dyes are ideal for adding tone, depth, or subtle color changes to bleached hair.
Permanent dyes, while offering long-lasting results, can be too harsh for bleached hair due to their high ammonia and peroxide content. The powerful chemicals are required to fully penetrate the hair cuticle, but this process can exacerbate existing damage and lead to breakage. If you choose to use a permanent dye, opt for a low-ammonia formula and perform a strand test to assess its impact on your hair’s condition before applying it to your entire head.
How can I prevent my bleached hair from turning green when I dye it?
Green tones appearing in bleached hair after dyeing are typically caused by mineral buildup, particularly copper, reacting with certain dye pigments. To prevent this, use a clarifying shampoo to remove any mineral deposits before dyeing. You can also use a chelating shampoo specifically designed to eliminate mineral buildup from hard water. This step creates a clean base for the dye to adhere to evenly.
Another crucial step is choosing a dye with warm undertones, such as gold or red, to counteract any potential green cast. Avoid dyes with cool or ashy tones, as these can exacerbate the issue. A strand test is highly recommended to observe how the dye interacts with your hair’s current condition. If you notice any green undertones emerging during the strand test, adjust your dye choice or seek professional advice.
What should I do if the dye color doesn’t turn out as expected on my bleached hair?
If the dye color doesn’t turn out as expected on your bleached hair, the first step is to assess the overall condition of your hair. If your hair feels damaged or excessively dry, focus on deep conditioning treatments before attempting any further color correction. Using a protein mask can help strengthen the hair and reduce porosity.
Depending on the severity of the color discrepancy, you have several options. For minor tonal adjustments, a color-depositing conditioner or gloss can help correct the hue. If the color is significantly different, you may need to remove the dye with a color remover specifically designed for delicate hair. Avoid using bleach again immediately, as this can cause further damage. If the issue is complex, consulting a professional colorist is recommended to avoid further complications.
How do I maintain the color of my dyed bleached hair?
Maintaining the color of dyed bleached hair requires a consistent and gentle hair care routine. Use sulfate-free shampoos and conditioners specifically formulated for color-treated hair. Sulfates can strip the hair of its color and natural oils, leading to fading and dryness. Limiting washing frequency to two or three times a week can also help preserve the color.
Incorporate color-depositing conditioners or masks into your routine to refresh the color between dye jobs. These products deposit pigment onto the hair shaft, helping to maintain the vibrancy and tone of your chosen color. Protect your hair from UV exposure by using a leave-in conditioner with UV protection or wearing a hat when spending time outdoors. Heat styling can also cause color fading, so use heat protectant sprays and minimize the use of hot tools.
When should I seek professional help after dyeing bleached hair?
Seeking professional help after dyeing bleached hair is recommended when you encounter significant damage, unexpected color results, or scalp irritation that doesn’t subside with home remedies. Signs of severe damage include excessive breakage, extreme dryness, or a gummy texture when wet. In these cases, a professional stylist can assess the extent of the damage and recommend appropriate treatments, such as protein bonding treatments or intensive conditioning masks.
If you experience severe scalp irritation, such as blistering, burning, or excessive itching, consult a dermatologist to rule out any allergic reactions or infections. Furthermore, if you are unhappy with the color outcome and are unsure how to correct it without causing further damage, a professional colorist can provide expert advice and perform color correction services safely. Attempting complex color corrections at home can often lead to more significant issues and potentially irreversible damage.
