Why Did My Hair Turn Purple When I Bleached It? Steps to Fix Your Hair Disaster [Updated: April 2025]

When you bleach your hair, it can become porous. This increased porosity can cause a purple toner to overdeposit, giving your hair a purple tint. To fix this, use a clarifying shampoo multiple times to wash out the excess toner. Always test new products on a small area first to prevent unexpected results.

To fix your hair disaster, first assess the extent of the discoloration. If your hair is only slightly purple, a clarifying shampoo can help remove excess color. For more pronounced purple tones, consider applying a color-correcting treatment. Use a warm-colored toner that neutralizes the purple, such as a yellow or gold-based toner. Always follow the instructions carefully to avoid further damage.

Once you address the purple tint, focus on hair recovery. Deep conditioning treatments can restore moisture and repair damage caused by bleaching. By taking these steps, you can effectively remedy your hair’s unexpected color shift and return it to a more natural shade.

What Causes My Hair to Turn Purple After Bleaching?

Bleaching hair can sometimes lead to unexpected colors like purple due to various chemical reactions. The main causes of this include underlying pigments, residual dye, and pH levels in the hair.

Underlying pigments
Residual dye
pH levels
Hair porosity
Product interactions

Understanding these factors is crucial for achieving the desired hair color after bleaching. Let’s explore each cause in detail.

Underlying Pigments: The presence of underlying pigments is a common reason hair turns purple after bleaching. Hair contains natural pigments, primarily eumelanin and pheomelanin. Eumelanin is responsible for darker colors, while pheomelanin produces warmer tones. When hair is bleached, eumelanin is removed first, often leaving behind yellow or orange tones. In some cases, these residual warm tones can mix with the bleach, resulting in a purple hue when exposed to certain hair products.
Residual Dye: If hair has previously been dyed, residual dye can influence the final color after bleaching. Some semi-permanent or permanent hair dyes contain remnants that react with the bleaching agent. This interaction can produce unintended colors. For example, blue dye can create purple tones when mixed with yellow from the natural pigments during the bleaching process.
pH Levels: The pH level of hair products influences color outcomes. Most bleach products have a high pH, making hair more alkaline. An alkaline environment can open the hair cuticle, potentially leading to a reaction with any existing pigments or minerals in the hair. When the pH is not balanced properly, it can lead to unexpected colors, including purples or greens.
Hair Porosity: Hair porosity refers to how well hair absorbs and retains moisture and products. High porosity hair can absorb more color and chemicals, making it more susceptible to unwanted hues after bleaching. If the hair is highly porous, it might also absorb residual pigments more effectively, leading to unanticipated color changes.
Product Interactions: Certain hair care products can react poorly post-bleaching, especially if they contain specific ingredients. For instance, shampoos and conditioners with purple pigments are designed to neutralize brassiness but can sometimes intensify purple tones in lighter bleached hair. Using compatible products is essential to avoid unwanted color shifts.

By recognizing these factors, you can take informed steps to manage and adjust your hair color after bleaching.

How Do Bleaching Agents Interact with Natural Hair Pigments?

Bleaching agents interact with natural hair pigments by breaking down melanin, the pigment that gives hair its color. This process leads to a lighter shade of hair. The interaction can be summarized as follows:

Chemical Composition: Bleaching agents typically contain hydrogen peroxide or ammonia. These chemicals penetrate the hair shaft and oxidize melanin. This oxidation process removes color, leading to lighter hair.
Melanin Breakdown: Hair has two types of melanin: eumelanin (black or brown) and pheomelanin (yellow or red). Bleach disrupts these pigments through oxidation. A study by H. A. Bergfeld et al. (2017) noted that higher concentrations of bleaching agents lead to more effective melanin breakdown.
Hair Structure Alteration: The bleaching process can weaken the hair structure. Bleach can open the cuticle, the outer layer of hair, making it more porous. This increased porosity can lead to dryness and damage. According to research published in the Journal of Cosmetic Science, excessively bleached hair shows significant changes in tensile strength and elasticity.
pH Levels: The pH of bleaching agents is usually alkaline. This high pH allows the chemicals to penetrate the hair more effectively. However, it can also cause the cuticle to lift, making hair susceptible to damage.
Color Outcomes: The resulting hair color depends on the original pigment and the type of bleach used. For example, hair that has a high concentration of eumelanin might turn brassy or orange if not properly prepped before bleaching. Studies indicate that the level of lifting needed influences the final color result after bleaching.

Understanding how bleaching agents interact with hair pigments is essential for achieving desired color outcomes while minimizing damage. Proper techniques and aftercare can mitigate the adverse effects of these chemical processes on hair health.

Why Does My Hair Type Influence the Bleaching Outcome?

Your hair type significantly influences the bleaching outcome due to its unique structure and properties. Different hair types absorb and respond to bleach in varying degrees, which affects color results, damage levels, and overall health post-treatment.

The American Academy of Dermatology defines hair type based on its texture, curl pattern, and porosity. Porosity refers to the hair’s ability to absorb moisture and products, which directly impacts how well it takes on color during the bleaching process.

Several underlying factors contribute to how hair type affects bleaching outcomes. Firstly, straight hair often has a smoother cuticle layer, which enables even distribution of bleach. In contrast, curly hair has a more irregular cuticle structure, leading to uneven color absorption. Secondly, the thickness of the hair strand also plays a role. Thicker strands may resist bleach more than thinner ones.

Bleaching agents work through a chemical process. They contain hydrogen peroxide, which penetrates the hair and lifts color by breaking down the melanin pigment. Melanin is the natural pigment that gives hair its color. When hair is porous, it absorbs bleach faster but may also sustain more damage. Conversely, low-porosity hair takes longer to bleach, as the cuticle layer is tightly sealed.

Specific conditions such as pre-existing hair damage or chemical treatments can further affect bleaching outcomes. For instance, hair that has been previously colored or chemically treated may react unpredictably, leading to unexpected results like uneven coloring or excessive damage. Additionally, factors like environmental exposure or hair care habits—such as using harsh shampoos or skipping deep conditioning—can influence the hair’s resilience during bleaching.

In summary, understanding your hair type—its texture, porosity, and current condition—will help you achieve a desirable bleaching outcome while minimizing damage. Consider consulting with a professional if unsure about the best approach for your specific hair characteristics.

What Are the Common Mistakes Leading to Purple Hair When Bleaching?

Bleaching hair can sometimes lead to an unintended purple hue. This often occurs due to specific mistakes made during the bleaching process.

Common mistakes leading to purple hair when bleaching:

Using a low-quality bleach.
Mixing bleach with the wrong developer.
Failing to perform a strand test.
Incorrect application technique.
Leaving bleach on for too long.
Using purple-toned shampoos or conditioners after bleaching.
Not understanding the hair’s original color.

These points highlight critical aspects to consider when bleaching hair. Now, let’s explore each of these mistakes in detail.

Using a Low-Quality Bleach: Using low-quality bleach can lead to unpredictable results. Low-grade products may contain impurities or ineffective ingredients that fail to lighten hair adequately, resulting in unwanted tones, including purple.
Mixing Bleach with the Wrong Developer: Mixing bleach with an improper developer strength can alter the outcome. A developer that is too strong can lighten hair too quickly, while a weak developer may not lift color efficiently. This can result in uneven lifting and color.
Failing to Perform a Strand Test: A strand test is essential before bleaching. It measures how your hair reacts to the bleach. Skipping this test can lead to surprises, such as purple or overly light results.
Incorrect Application Technique: Application techniques matter greatly in bleaching. Applying bleach unevenly can cause patchy color and unwanted shades. It’s crucial to section hair appropriately and ensure even saturation.
Leaving Bleach on for Too Long: Overprocessing hair by leaving bleach on too long can damage hair and cause it to take on unwanted colors. Hair may become overly porous, leading to darker or muddier tones, including purple.
Using Purple-Toned Shampoos or Conditioners After Bleaching: Some purple shampoos are designed to neutralize brassy tones. However, using them immediately after bleaching can deposit too much purple pigment on freshly bleached hair, causing an unintended purple tint.
Not Understanding the Hair’s Original Color: The starting color of your hair plays a significant role in the final shade after bleaching. Darker hair often pulls more warm tones during the processing, which may mix with bleach, influencing the final color found.

By understanding these common mistakes, one can better prepare for a successful bleaching process, minimizing the risk of ending up with purple hair.

Did I Use an Inappropriate Developer Strength for My Bleach?

Did you use an inappropriate developer strength for your bleach? Yes, incorrect developer strength can lead to unexpected hair color results.

First, identify the developer strength you used. Developer strength is measured in volumes, typically 10, 20, 30, or 40. Each volume provides different levels of lift or lightening.

Next, consider the level of lift needed for your desired hair color. A lower volume, like 20, may lighten hair one to two shades. A higher volume, such as 40, can lighten hair more drastically but may cause damage.

Then, assess your starting hair color. Darker colors require higher developer strength to lift to lighter shades effectively.

Finally, connect these elements. If your developer strength was too high for your hair’s starting color or condition, it could cause uneven or unintended results, such as purple tones.

In summary, using the wrong developer strength likely caused your hair to turn purple. Always match developer strength carefully with your hair type and desired outcome to avoid these issues.

Have I Left the Bleach on My Hair for Too Long?

Have you left the bleach on your hair for too long? If you notice excessive dryness, brittleness, or a strong burning sensation, you likely left the bleach on too long. Bleach contains strong chemicals that can damage hair if not monitored closely.

To assess the situation, follow these steps:

Check your hair’s condition. Look for signs of damage such as frizz, breakage, or an unnatural texture. These indicate possible over-processing.
Conduct a strand test. Take a small section of hair that has been bleached. Rinse it with water and observe the texture and color. If it feels rough or looks damaged, the bleach may have been on too long.
Evaluate the time duration. Depending on the hair type, bleach should typically be applied for 20 to 45 minutes. Exceeding this time frame increases the risk of damage.
Rinse immediately. If you suspect over-bleaching, rinse the bleach out right away with cool water. This stops further processing.
Condition your hair. After rinsing, apply a deep conditioner. This helps to hydrate and restore moisture to damaged hair.

In summary, if you notice significant damage or discomfort, you have likely left the bleach on for too long. Take immediate action by rinsing and conditioning your hair to minimize further harm.
