What Happens if You Put Bleach Over Dyed Red Hair: Understanding the Risks and Outcomes

The allure of changing one’s hair color is a timeless fascination, with many individuals venturing into the vibrant world of red hair dye. However, the inclination to further alter dyed red hair, perhaps to achieve a lighter or drastically different shade, can lead to the consideration of using bleach. Before taking such a step, it’s crucial to understand the implications and potential outcomes of applying bleach over previously dyed red hair. This article delves into the chemical process, the risks involved, and the possible results, aiming to guide those contemplating this hair transformation.

Introduction to Hair Bleaching and Dyeing

Bleaching and dyeing are two common hair treatments used to alter hair color. Bleaching is a chemical process that removes pigment from the hair shaft, making it lighter. It works by breaking down the melanin (the pigment responsible for hair color) in the hair. On the other hand, dyeing, especially when it comes to vibrant colors like red, involves depositing color onto the hair shaft. Red hair dye, in particular, is known for its semi-permanent nature and difficulty in removing once applied.

The Chemistry Behind Red Hair Dye and Bleach

Understanding the chemistry behind both red hair dye and bleach is essential to predicting the outcome of combining these treatments. Red hair dye contains colorants that bind to the keratin in the hair, giving it the desired red hue. These colorants can penetrate the hair shaft to varying degrees, depending on the type of dye used (semi-permanent, demi-permanent, or permanent).

Bleach, which typically contains hydrogen peroxide as its active ingredient, is designed to lift the natural pigment out of the hair. The process involves the penetration of the bleach into the hair shaft, where it breaks down the existing melanin. This process can be harsh, leading to potential damage, especially if the hair is already compromised from previous color treatments.

Risks of Applying Bleach Over Dyed Red Hair

When bleach is applied over dyed red hair, several risks come into play. One of the most significant concerns is over-processing, which occurs when the bleach penetrates too deeply into the hair shaft, causing excessive damage. Over-processed hair may feel brittle, look dull, and even lead to breakage.

Another risk is the unpredictable color outcome. Because red hair dye can be particularly stubborn, the bleach may not lift the color evenly or as expected. This can result in uneven toning, where parts of the hair appear brassy, orange, or patchy, rather than achieving the desired lighter shade.

Furthermore, applying bleach over previously dyed hair increases the risk of hair porosity issues. Hair porosity refers to how well the hair can absorb and retain moisture. When hair is over-processed, its porosity can become compromised, leading to dryness, frizz, and further damage.

Expected Outcomes of Bleaching Dyed Red Hair

The outcome of bleaching dyed red hair can vary greatly depending on several factors, including the original color of the hair, the type of red dye used, the condition of the hair before bleaching, and the bleaching technique employed. Generally, bleaching over red dye can lead to a range of colors, from orange and brassy tones to, in some cases, a lighter, more pastel version of the original red color, though this is less common.

If the goal is to achieve a lighter, non-red color, multiple bleaching sessions may be necessary, which significantly increases the risk of damage. It’s also important to note that some red dyes, especially those containing temporary or semi-permanent colorants, may wash out or fade more easily than permanent dyes, potentially affecting the bleaching outcome.

Minimizing Risks: Pre-Bleach Preparation and Post-Bleach Care

To minimize the risks associated with bleaching over dyed red hair, pre-bleach preparation is crucial. This includes ensuring the hair is in the best possible condition before the treatment. Using moisturizing treatments and avoiding heat styling in the weeks leading up to the bleach application can help maintain the hair’s integrity.

After bleaching, post-bleach care is equally important. This involves using sulfate-free shampoos and deep conditioning treatments to help repair and restore the hair’s moisture balance. Protein treatments can also be beneficial in repairing any damage to the hair’s structure.

Professional Advice and Alternatives

Given the potential risks and unpredictable outcomes, seeking professional advice from a skilled hairstylist is highly recommended. Professionals can assess the condition of the hair and provide guidance on the best course of action to achieve the desired color while minimizing damage.

For those looking to change their red-dyed hair without the risks associated with bleaching, there are alternatives. These include using color depositing treatments or toners to adjust the shade without lifting the original color, or opting for a color correction service with a professional stylist.

Conclusion

The decision to bleach over dyed red hair should not be taken lightly. Understanding the chemical processes involved, the potential risks, and the variability of outcomes is essential for making an informed decision. By recognizing the importance of pre-bleach preparation, post-bleach care, and considering professional advice and alternatives, individuals can navigate the complex world of hair color alteration with greater confidence and fewer regrets. Whether the goal is to achieve a lighter shade, remove unwanted color, or simply to experiment with a new look, prioritizing hair health and seeking expert guidance can make all the difference in the pursuit of vibrant, healthy-looking hair.

In conclusion, while bleaching over dyed red hair can be a risky endeavor, being well-informed and prepared can help mitigate these risks, leading to a more successful and satisfying hair transformation experience.

What happens when you put bleach over dyed red hair?

When you put bleach over dyed red hair, the results can be unpredictable and often undesirable. The bleach can cause the color to lift unevenly, leading to a range of unwanted tones and shades. In some cases, the red pigment may resist the bleaching process, resulting in a warm, brassy tone that can be difficult to correct. Additionally, the bleach can damage the hair cuticle, leading to dryness, brittleness, and breakage. This is because the bleach penetrates the hair shaft, breaking down the keratin bonds and causing the hair to become weak and prone to damage.

The extent of the damage depends on several factors, including the type of bleach used, the porosity and condition of the hair, and the amount of time the bleach is left on. To minimize the risks, it’s essential to use a high-lift bleach specifically designed for color-treated hair and to follow the instructions carefully. It’s also crucial to perform a strand test before applying the bleach to the entire head to ensure the desired results and to check for any adverse reactions. By taking these precautions, you can reduce the risk of damage and achieve a more predictable outcome when putting bleach over dyed red hair.

Can bleach remove red hair dye completely?

Bleach can remove some of the red pigment from dyed red hair, but it may not completely eliminate the color. The effectiveness of the bleach depends on the type of dye used, the porosity of the hair, and the number of applications. In general, bleach is more effective at removing temporary or semi-permanent dyes than permanent dyes. However, even with permanent dyes, bleach can still lift the color to some extent, although it may require multiple applications. It’s also important to note that bleach can be more challenging to apply to virgin hair (hair that has not been previously colored or chemically treated) as the cuticle is more compact and resistant to penetration.

To increase the chances of removing the red dye completely, it’s essential to use a high-strength bleach and to apply it multiple times, spacing out the applications to avoid excessive damage. However, even with repeated applications, it’s unlikely that the bleach will completely remove the red pigment, and some residual color may remain. In such cases, toning or glossing treatments can be used to adjust the tone and achieve a more desirable shade. It’s also crucial to consider the condition and health of the hair before attempting to remove the dye, as excessive bleaching can cause significant damage and breakage.
