Bleaching over previously colored hair, especially hair that has been dyed blue, can be a daunting task. The outcome is often unpredictable, and the process can be damaging to the hair if not done correctly. In this article, we will delve into the world of hair bleaching, focusing on the specific challenges and considerations of bleaching over blue dyed hair. We’ll explore the basics of hair bleaching, the effects of bleaching over colored hair, and provide a step-by-step guide on how to achieve the best results safely.
Understanding Hair Bleaching
Hair bleaching is a chemical process that lightens the hair color by breaking down the melanin pigment in the hair shaft. Melanin is responsible for the color of our hair, and there are two types: eumelanin, which produces brown and black colors, and pheomelanin, which produces red and yellow colors. The combination of these two types of melanin determines our natural hair color. When you bleach your hair, you are essentially removing or breaking down these melanin pigments to achieve a lighter shade.
The Chemistry Behind Bleaching
The bleaching process involves the use of hydrogen peroxide, a common oxidizing agent. Hydrogen peroxide penetrates the hair shaft, breaking down the melanin pigment. The higher the concentration of hydrogen peroxide, the lighter the hair will become. However, higher concentrations also increase the risk of hair damage, as they can strip the hair of its natural oils and cause it to become dry and brittle.
Considerations for Colored Hair
When it comes to bleaching over previously colored hair, the process becomes more complex. The existing color can affect how well the bleach penetrates the hair shaft and the final color outcome. It’s crucial to understand that colored hair has already undergone significant chemical processing, which can make it more prone to damage from further chemical treatments like bleaching.
Bleaching Over Blue Dyed Hair: Challenges and Considerations
Blue dyed hair presents a unique challenge for bleaching. The blue pigment is typically more stubborn than other colors, as it is often achieved with semi-permanent or demi-permanent dyes that are designed to last longer. When you bleach over blue dyed hair, you risk facing several challenges:
Predicting the Outcome
The outcome of bleaching over blue dyed hair can be unpredictable. The blue pigment may not lift evenly, leading to patchy or uneven color distribution. Additionally, the final color may not be what you expect, as the interaction between the bleach and the existing blue dye can produce unexpected shades or tones.
Avoiding Damage
The primary concern when bleaching over colored hair is minimizing damage. Colored hair is already compromised, and adding bleach to the equation can lead to over-processing, which results in dry, brittle hair that is prone to breakage. Using the right products and following a careful process is essential to maintaining the health and integrity of your hair.
A Step-by-Step Guide to Bleaching Over Blue Dyed Hair
If you’ve decided to proceed with bleaching your blue dyed hair, here’s a step-by-step guide to help you achieve the best possible results:
Pre-Bleaching Preparation
Before you start the bleaching process, prepare your hair with a pre-bleach treatment. This can include a deep conditioning treatment to moisturize your hair and a color remover to help lift the existing blue dye. It’s also essential to perform a strand test to gauge how your hair will react to the bleach.
Choosing the Right Bleach
Select a high-quality bleach that is appropriate for your hair type and the level of lift you desire. Higher volume developers (like 20 volume) will lift the color more, but they also increase the risk of damage. For previously colored hair, it’s often recommended to start with a lower volume developer and gradually increase as needed.
Applying the Bleach
When applying the bleach, be sure to follow the instructions carefully. Apply the bleach mixture to your hair, starting at the roots and working your way down to the ends. Processing time will depend on the type of bleach you’re using and the condition of your hair. Keep a close eye on the processing time, as over-processing can lead to significant damage.
Post-Bleaching Care
After bleaching, it’s crucial to moisturize and nourish your hair. Use a deep conditioning treatment immediately after bleaching and consider using a hair mask once a week to keep your hair healthy and strong. Avoid using heat styling tools or further chemical treatments for a while, as this can exacerbate any damage caused by the bleaching process.
Conclusion
Bleaching over blue dyed hair can be a challenging process, but with the right approach and careful consideration, you can achieve the desired results while minimizing damage to your hair. Remember, patience and preparation are key. Always prioritize the health and integrity of your hair, and don’t hesitate to seek professional advice if you’re unsure about any part of the process. Whether you’re looking to dramatically change your hair color or simply to remove an unwanted dye job, understanding the ins and outs of bleaching over colored hair can empower you to make informed decisions about your hair care.
Can you bleach over blue dyed hair without causing damage?
Bleaching over blue dyed hair can be a challenging and potentially damaging process. The blue dye can be difficult to lift, and the bleaching process may require multiple applications, which can cause significant stress to the hair. Additionally, the alkalinity of the bleach can disrupt the hair’s cuticle layer, leading to dryness, brittleness, and breakage. To minimize the risk of damage, it’s essential to approach the bleaching process with caution and to take steps to protect the hair, such as using a gentler bleach, applying a pre-bleach treatment, and following up with a moisturizing conditioner.
To achieve the best results, it’s recommended to consult a professional hairstylist who has experience with bleaching and color correction. They can assess the condition of your hair and provide personalized guidance on the best course of action.
