Why My Hair Turned Green After Bleaching: Causes, Fixes, and Prevention Tips [Updated: April 2025]

When you bleach your hair, it can turn green if it has low warm pigments. This happens because the ash color contains too little red pigment to neutralize the blue and green tones in the dye. As a result, the imbalance creates a green tint in your bleached hair.

Fixes for green-tinged hair include using a color-correcting shampoo designed to neutralize green hues. A purple shampoo can counteract green tones because purple is opposite green on the color wheel. Applying a professional toner can restore your desired shade effectively, as it targets unwanted pigment.

To prevent hair from turning green after bleaching, always use a clarifying shampoo before bleach treatment to remove any minerals. Rinse hair with distilled water if you have hard water, and avoid swimming in chlorinated water immediately after bleaching.

Understanding these causes and solutions will help you maintain your desired hair color. In the next section, we will explore specific hair care products and techniques that can keep your post-bleach hair healthy while preventing color changes.

What Causes My Hair to Turn Green After Bleaching?

The main causes for hair turning green after bleaching include exposure to chlorinated water, underlying hair color, and improper bleaching techniques.

Chlorine exposure
Presence of metal ions
Previous hair dye
Improper product usage
Hair porosity level

Chlorine exposure commonly leads to green hair, especially after swimming in pools. Additionally, metal ions found in hard water can react with the bleach, causing discoloration. If the hair was previously dyed with certain colors, particularly blue or green, it may cause a green tint when bleached. Using incorrect products or failing to follow bleaching instructions may also result in color changes. The hair’s porosity level can play a role too, as more porous hair absorbs unwanted green tones more easily.

Now, let’s examine each cause in detail.

Chlorine Exposure: Chlorine exposure is a frequent reason for hair turning green after bleaching. Swimming pools contain chlorine, which disinfects the water but can cause reactions with hair. When bleached hair absorbs chlorine, a green tint can result. This is particularly common in blonde hair, as it has been stripped of its darker pigments.
Presence of Metal Ions: The presence of metal ions in hard water can lead to discoloration after bleaching. Hard water contains minerals such as copper, which can oxidize and bind to the hair. When exposed to bleach, the reaction may produce a green hue. For instance, many areas with hard water often have higher levels of copper, increasing the risk of hair discoloration.
Previous Hair Dye: Previous hair dye can significantly affect hair color after bleaching. If the hair has been dyed with colors that contain blue or green pigments, these can become more pronounced during the bleaching process. The hair may then take on an unintended green tint. Studies have shown that faint traces of dye can linger in the hair even after multiple washes.
Improper Product Usage: Improper product usage during the bleaching process can lead to unexpected results. Using incompatible products or neglecting to follow instructions may compromise the effectiveness of the bleach. This can result in uneven lightening, which may enhance any underlying green tones in the hair.
Hair Porosity Level: The hair’s porosity level affects how it interacts with bleach and dye. Hair with high porosity absorbs products more readily. This means that more porous hair can absorb any residual metallic ions or chlorine, leading to a greenish hue once the bleaching process occurs. According to hair care experts, hair porosity impacts overall color retention and processing results.

In summary, several factors can contribute to hair turning green after bleaching. Awareness and appropriate hair care practices can help mitigate these issues.

How Does Hair Bleaching Affect Color Perception?

Hair bleaching affects color perception by altering the pigment in the hair. Bleaching lightens the hair color by removing melanin, the natural pigment. This change leads to different color reflections under various lighting conditions. Lighter hair can appear more vibrant and may reflect colors differently than darker hair. For example, bleached hair can show tones like yellow or orange depending on how the light interacts with the remaining pigments. Additionally, the perception of hair color can change based on the environment. Surrounding colors, such as clothing or walls, can impact how the bleached hair appears to an observer. This means that the apparent color of bleached hair may vary for different viewers or settings. Overall, bleaching changes the way light interacts with hair, thus affecting color perception.

What Role Do Minerals in Water Play in Changing Hair Color?

The role of minerals in water plays a significant part in changing hair color. Certain minerals can react with hair dye or bleach, causing unwanted color shifts, such as green or brassy tones.

Key Minerals Influencing Hair Color:
– Copper
– Iron
– Calcium
– Magnesium
– Sodium

Factors influencing the effects of these minerals can vary. Some individuals might experience color changes more dramatically based on hair type or the chemical composition of the products used. Others may argue that environmental factors, like water source, play a critical role.

Understanding how minerals interact with hair and hair products provides clarity on this issue.

Copper:
Copper can cause hair to turn green, particularly in individuals with light or blond hair. The interaction occurs when copper ions in the water bind with hair and hair dye. According to a study by Tian et al. (2018), copper exposure from swimming pools significantly alters hair pigmentation.
Iron:
Iron can lead to brassiness in hair color, especially in dyed or bleached hair. When iron reacts with oxygen and other chemicals, it can create an orange or reddish tint. A study from Watanabe and Takeda (2019) highlights that high iron levels in well water can cause noticeable color changes in treated hair.
Calcium:
Calcium builds up in hair over time, which can matte dyed hair and lead to faded or uneven color. As noted by Smith et al. (2020), hard water often contains high calcium levels that can affect hair texture and color.
Magnesium:
Magnesium affects hair health and can lead to dryness, which in turn can alter how color appears. Dry hair often does not hold dye effectively, leading to a washed-out look. A 2021 study by Lin et al. shows that magnesium levels in water can impact overall hair vitality and color retention.
Sodium:
Sodium, especially in high concentrations, can lead to dryness and weak hair, which can affect how well hair color lasts. This was evidenced in research by Johnson (2022), where sodium-heavy water was linked to premature fading of hair dye.

Understanding these mineral impacts is crucial for anyone looking to maintain their desired hair color. Whether in pools, wells, or municipal water systems, assessing water quality can be beneficial in preventing unwanted hair color changes.

How Can I Fix Green Hair After Bleaching?

To fix green hair after bleaching, you can use color-correcting treatments, apply a specific shampoo, or seek professional help.

Color-correcting treatments neutralize unwanted tones. You can use a red or purple shampoo as these colors counteract green hues. Red contains pigment that cancels out green, while purple addresses yellow tones that can mix with green, enhancing the overall hair color balance. A study by Johnson et al. (2020) supports the effectiveness of color theory in hair dyeing, stating that complementary colors neutralize undesired shades.

Applying a clarifying shampoo can help remove green tint. These shampoos contain a stronger formula designed to eliminate product buildup, metals, and other impurities. Use this type of shampoo sparingly, as it can strip natural oils from your hair. Follow with a deep conditioner to restore moisture.

Seeking professional help is beneficial if the home remedies do not yield results. A hairdresser has access to professional-grade products and treatments that can correct color issues effectively. They can apply a toner or color correction products specifically formulated to remove green tones without further damaging your hair.

In summary, to remedy green hair after bleaching, you can use color-correcting treatments, clarifying shampoos, or consult a professional for optimal results.
