Why Does Your Hair Turn Green After Stripping and Bleaching?

Are you frustrated by the unexpected green shade that appeared on your hair after bleaching and stripping it? This article will explore the underlying reasons for this phenomenon and provide valuable insights for preventing future issues.

Underlying Pigments in Natural Hair

Natural hair contains various pigments, predominantly eumelanin (dark pigments) and pheomelanin (light pigments). When hair undergoes bleaching, these pigments are removed, revealing underlying tones. If your hair was previously dyed, especially with darker colors, the bleach might strip away the color but leave residual tones, such as green hues.

Oxidation of Hair

Bleaching involves the use of strong chemicals, such as hydrogen peroxide, which can trigger a reaction with existing color molecules in the hair. Blue or green dyes present in previous hair colors may become more pronounced after bleaching. This is a common occurrence, especially when transitioning from dark to light or pastel hues.

Ph Level and Hair Porosity

Bleaching raises the pH level of the hair, affecting how pigments adhere to the hair structure. This can lead to unexpected color changes, including greenish tones. Porous or damaged hair is more susceptible to these changes, making it harder to achieve consistent and predictable results.

Water Quality and Mineral Interactions

The presence of minerals in water, such as copper from old pipes, can react with the bleach or the hair itself, resulting in a green tint. This is particularly common in areas with hard water. Using distilled or filtered water can help mitigate these issues.

Improper Color Correction

Incorrect color correction techniques can also lead to greenish hues. If you attempt to tone or dye your hair without using proper color theory, such as using a warm tone to counteract cool tones, you might inadvertently create a greenish hue during the bleaching process.

To avoid this issue:

Use a color remover: Consider using a color remover before bleaching to ensure a clean slate. Consult a professional: If you're unsure, consult a professional stylist with experience in hair color to guide you through the process. Use the right products: Choose color correction products that are designed to neutralize green tones, such as color correcting balms and toners. Practise caution: Always follow manufacturer instructions for bleaching and toning to minimize the risk of unwanted color changes.

In conclusion, hair turning green after stripping and bleaching is often a result of complex interactions between hair chemistry, pigments, and the bleaching process. With careful consideration and the right professional guidance, you can achieve your desired hair color without encountering unexpected green tones.
