Why Did My Hair Turn Purple When I Bleached It? Common Mistakes and Fixes Explained

Your hair turned purple after bleaching because leftover violet pigments from toner or certain shampoos stayed in your hair. The bleaching process may have been uneven, causing some strands to keep color. A clarifying shampoo can help remove this tint. Over-processing may also have damaged your hair and affected color absorption.

Improper bleach application contributes to the problem. Uneven coverage can leave some hair less processed, resulting in a patchy hue. Additionally, using the wrong strength of bleach can lead to unwanted tones. High-volume hydrogen peroxide may produce more lift, but it also increases the risk of color changes.

To fix this issue, consider a color-correcting shampoo or a toner specifically designed for unwanted purple hues. Toning products neutralize unwanted colors by depositing complementary shades back into the hair. Maintaining proper care and using suitable products post-bleach can also help retain your desired shade.

In the following section, we will explore specific techniques and products that can help you achieve the perfect blonde without any unintended tones.

What Causes Hair to Turn Purple When I Bleached It?

Bleaching hair can sometimes result in an unexpected purple hue due to chemical reactions between pigments and hair dye remnants. This change often occurs when the hair is lightened, revealing underlying tones or reacting with leftover color.

1. Residual Hair Dye
2. Hair’s Natural Undertones
3. pH Imbalance
4. Bleach Composition
5. Water Quality

When considering these factors, it’s essential to understand how they interact and contribute to the hair color change during bleaching.

1. Residual Hair Dye: Residual hair dye refers to leftover color in the hair from previous treatments. When bleaching, the chemicals in the bleach can interact with these colors, leading to unexpected tints like purple. For example, if someone previously dyed their hair with a blue or violet shade, the bleach can lift that color, resulting in purples or greens. A study by Zhang et al. (2019) emphasized the importance of removing all previous dyes before bleaching to avoid such outcomes.

2. Hair’s Natural Undertones: Hair’s natural undertones can influence resulting color after bleaching. Each person has unique undertones, which can be warm (yellow, orange) or cool (blue, violet). After bleaching, these undertones may become more visible, potentially resulting in an unintended purple hue. According to Hair Color Confessions (2020), understanding one’s undertones is crucial for achieving the desired shade.

3. pH Imbalance: pH imbalance occurs when the chemical processes of bleaching alter the hair’s natural pH level. Hair normally has a slightly acidic pH of around 4.5 to 5.5. If bleach raises this pH, it can weaken the hair structure and disturb color balance, leading to unexpected tones. Studies suggest that a balanced pH during hair treatment helps maintain desired color outcomes and hair health.

4. Bleach Composition: Bleach compositions vary, with some containing stronger oxidizing agents than others. Stronger formulations can remove color faster, sometimes revealing unwanted pigments. Using products with varying levels of ammonia or peroxide can further influence the final result. According to Vogue’s Hair Science section (2021), choosing the right bleach formula can significantly reduce unintended color issues.

5. Water Quality: Water quality can impact the final result of bleaching. Hard water, which contains high mineral content, can interact with the chemicals in bleach, possibly resulting in color changes. Research suggests that using filtered or distilled water can help achieve more consistent hair coloring results.

Understanding these factors can help individuals minimize purple outcomes when bleaching hair and achieve the desired shade more effectively.

Which Chemical Reactions Can Lead to Purple Tones in Hair?

The chemical reactions that can lead to purple tones in hair primarily occur during hair dyeing processes and specific interactions with bleaching agents.

1. Use of Purple Shampoo
2. Hair Bleaching
3. Direct Dyes
4. Color Correction Techniques
5. Reactions with Water Hardness

These factors demonstrate the diverse ways purple tones can emerge in the hair, from routine hair care products to chemical interactions in coloring and bleaching. While purple shampoo is widely embraced for its toning properties, some may argue that it can leave hair feeling dry or dull. Others may prefer opting for direct dyes or specific color correction treatments to achieve the desired shade.

1. Use of Purple Shampoo:
   The use of purple shampoo creates purple tones in hair by utilizing violet pigments. Purple shampoo is primarily designed for blonde and silver hair. The shampoo works by neutralizing yellow tones that may develop over time due to environmental factors or product buildup. Studies show that color theory in hair care suggests that purple is opposite yellow on the color wheel. Therefore, it effectively diminishes brassy undertones. Commonly, brands like Fanola and Joico offer such products.

2. Hair Bleaching:
   Hair bleaching leads to purple tones through the chemical process of decolorization. When hair is bleached, the natural pigments are removed, which can sometimes reveal underlying unwanted hues. If the hair is over-bleached, it may develop a yellow or orange tone, and using purple toner afterward can help neutralize these colors. Research by D. A. Urquhart et al. (2018) emphasizes that balancing tonal properties can enhance the aesthetic outcome of bleached hair.

3. Direct Dyes:
   Direct dyes are semi-permanent hair color products that impart vibrant shades, including purple. These dyes coat the hair shaft with color, enabling striking and vivid results without the need for ammonia or peroxide. Notably, many brands offer direct dye that can deposit purple tones accurately and effectively. According to a market analysis by Statista (2021), such creative and bold styles are increasingly popular among younger demographics.

4. Color Correction Techniques:
   Color correction techniques are methods employed to adjust unwanted hair colors, which can lead to purple tones when specific products or formulations are used. For instance, a purple-based toner applied over orange-yellow hair helps create a cooler hue. Professional colorists often utilize the principles of color theory to remediate color mismatches effectively. A case study by D. R. Smith (2020) demonstrated how color correction techniques can transform hair hues and provide satisfying results in beauty salons.

5. Reactions with Water Hardness:
   Reactions with water hardness can also result in purple tones. Hard water contains high levels of minerals such as calcium and magnesium, which can interact with hair products. Such minerals can sometimes leave a hue that appears purplish in character. A study by F. J. Choi et al. (2019) highlights that water quality directly impacts the effectiveness of shampoos and conditioners, potentially leading to unusual color results.

How Do Hair Porosity and Previous Treatments Affect Bleaching Results?

Hair porosity and previous treatments significantly influence bleaching results. Higher porosity and prior chemical treatments can lead to uneven lightening, damage, and unexpected color outcomes.

Hair porosity refers to the hair’s ability to absorb and retain moisture. It affects how products, including bleach, interact with hair. There are three porosity levels:

• Low porosity: This hair type has tightly packed cuticles. It resists moisture absorption, which can result in uneven bleaching. Bleach may not penetrate the hair fibers effectively.
• Medium porosity: Hair with medium porosity absorbs and retains moisture well. This porosity level generally achieves more consistent bleaching results, as bleach can penetrate evenly.
• High porosity: This hair type has raised cuticles, allowing for quick absorption and loss of moisture. High porosity hair may bleach rapidly but can also become damaged or over-processed, showing signs of dryness and frizz.

Previous treatments also play a crucial role in bleaching performance. These treatments include:

• Chemical relaxers: These can alter the hair’s structure. Bleaching on previously relaxed hair can lead to excessive damage and unpredictable results.
• Coloring treatments: Hair that has been dyed may have absorbed pigments, which can affect the final shade post-bleach. Certain colors, particularly dark ones, may remain despite bleaching, leading to unwanted tones.
• Heat treatments: Frequent use of heat styling tools can weaken hair. Bleaching damaged hair can exacerbate breakage and lead to uneven results.

In summary, understanding both hair porosity and the effects of prior treatments is vital for achieving desired bleaching outcomes. Selection of appropriate techniques and products must align with individual hair characteristics to minimize damage and achieve uniform color.

What Mistakes Can Result in Unintended Purple Hair?

Mistakes that can result in unintended purple hair include incorrect dye usage and improper bleaching techniques.

1. Using the wrong developer strength
2. Mixing different dye brands
3. Failing to conduct a strand test
4. Leaving bleach or dye on hair for too long
5. Not clarifying hair before dyeing
6. Dyeing over previously treated hair without adequate preparation

These common mistakes can lead to unwanted results, including a purple tint in hair. Understanding each issue helps in addressing the risks associated with hair coloring.

1. Using the Wrong Developer Strength:
   Using the wrong developer strength causes unexpected hair color outcomes. Developers typically come in 10, 20, 30, or 40 volume strengths, affecting how much color lifts or deposits. For example, a 30-volume developer can lift hair significantly. However, if the bleach process lifts hair too much, excess warmth can lead to a purple or undesired hue.

2. Mixing Different Dye Brands:
   Mixing different dye brands can create unpredictable results. Each brand has unique formulations and pH levels. As a result, when blended, the chemical reactions may produce an unusual color, including purple. Hair color expert Julia L. warns against combining brands without clear guidance as it often leads to unexpected outcomes.

3. Failing to Conduct a Strand Test:
   Failing to conduct a strand test risks unwanted hair color. A strand test determines how hair responds to dye or bleach. By testing a small section, individuals can see the results before applying the product to the entire head. Skipping this step can cause unexpected colors, such as purple or blue undertones, especially in light hair.

4. Leaving Bleach or Dye on Hair for Too Long:
   Leaving bleach or dye on hair for too long can lead to over-bleaching. This process disrupts the hair cuticle, resulting in unwanted pigmentation changes, including purple tones. Hair can become porous and absorb extra pigments from surrounding products or water. As colorist Sarah N. suggests, adhering to recommended processing times is crucial for desirable results.

5. Not Clarifying Hair Before Dyeing:
   Not clarifying hair before dyeing allows leftover products to interfere with color. Product buildup from styling products or conditioners can prevent even dye distribution. This results in patches of color not adhering well and may create a purple or uneven appearance. Hair professionals recommend using a clarifying shampoo prior to any dyeing process for better results.

6. Dyeing Over Previously Treated Hair Without Adequate Preparation:
   Dyeing over previously treated hair without adequate preparation may lead to unexpected color results. Hair that has been previously colored tends to absorb new colors differently. An improper approach can cause a purple or gray tone to show up, especially if there is a contrast between the previous dye and the new one. Using a color remover or waiting for previous color to fade is advisable for best outcomes.

Did I Use the Appropriate Developer Strength for My Hair Type?

To determine if you used the appropriate developer strength for your hair type, start by identifying your hair’s characteristics. Consider your hair type, its thickness, and its current condition. Fine or damaged hair typically requires a lower developer strength, such as 10 or 20 volume, to avoid excessive processing. In contrast, coarse or resistant hair might need a higher strength, such as 30 or 40 volume, for effective lightening.

Next, assess the developer strength you used. If you selected a higher volume developer on fine or damaged hair, this choice can lead to over-processing. Over-processing can cause hair to become brittle or change color unexpectedly, such as turning purple when bleaching. This reaction often occurs due to the interaction of the bleach with underlying pigments in your hair.

Compare your hair type with the recommended developer strengths. You should select a developer that matches the condition and needs of your hair. If you have doubts, consider consulting a professional stylist. They can provide guidance tailored to your specific hair type and desired outcome.

In summary, if your hair turned purple, it may indicate that the developer strength used was too high for your hair type. Adjusting the developer strength to align with your hair characteristics can help achieve the desired results without damage.

Was the Bleach Left on My Hair for Too Long or Too Short a Time?

To determine if the bleach was left on your hair for too long or too short a time, consider these factors: the desired hair color, your natural hair color, and the strength of the bleach.

First, if you left the bleach on for too long, your hair may become overly lightened or develop unwanted tones, such as purple or orange. This happens because prolonged exposure can damage the hair and affect the pigments.

Next, if the bleach was on for too short a time, your hair may not lighten adequately. It may look brassy or maintain its original color due to insufficient processing time.

Evaluate the results. If your hair appears overly processed with a light color or a wrong tone, you likely left it on too long. If it’s still dark or brassy, then it was likely not on long enough.

In summary, assess your hair’s color outcome and relate it to your processing time to conclude whether the bleach was left on too long or too short.
