Bleaching dyed black hair can be a daunting task, especially for those who are new to hair care and styling. The process requires patience, dedication, and a thorough understanding of the chemicals involved. In this article, we will delve into the world of hair bleaching, exploring the best practices, potential risks, and essential tips for achieving the perfect shade.
Understanding Hair Bleaching
Hair bleaching is a chemical process that involves breaking down the pigment in the hair shaft to achieve a lighter color. The process can be used to remove existing color, lighten natural hair color, or create a blank canvas for new colors. When it comes to bleaching dyed black hair, the goal is to remove the existing pigment and replace it with a new, lighter shade.
The Chemistry of Hair Bleaching
The chemistry of hair bleaching is complex and involves several key components. The primary ingredients in hair bleach are hydrogen peroxide and ammonia. Hydrogen peroxide is the oxidizing agent that breaks down the pigment in the hair shaft, while ammonia is a alkalizer that opens up the hair cuticle to allow the bleach to penetrate. The combination of these two ingredients determines the strength and effectiveness of the bleach.
Factors Affecting Bleach Strength
The strength of the bleach is affected by several factors, including the concentration of hydrogen peroxide, the volume of developer, and the processing time. A higher concentration of hydrogen peroxide will result in a stronger bleach, while a longer processing time will allow the bleach to penetrate deeper into the hair shaft. However, it is essential to note that over-processing can cause damage to the hair, leading to breakage, dryness, and Split ends.
Preparing for the Bleaching Process
Before bleaching dyed black hair, it is essential to prepare the hair and scalp for the chemical process. This includes:
Assessing Hair Condition
It is crucial to assess the condition of the hair before bleaching. Hair that is damaged, over-processed, or fragile may not be suitable for bleaching. A hair strand test can help determine the condition of the hair and identify any potential risks.
Choosing the Right Bleach
Selecting the right bleach for dyed black hair is critical. There are several types of bleach available, including powder bleach, cream bleach, and high-lift bleach. Powder bleach is the most common type and is available in various strengths. Cream bleach is gentler and more suitable for damaged or fragile hair. High-lift bleach is the strongest and is used for dramatic color changes.
The Bleaching Process
The bleaching process involves several steps, including:
Applying the Bleach
The bleach is applied to the hair in a specific manner, usually in a sectional pattern. The bleach is worked through the hair, from roots to ends, using a gentle, sweeping motion. It is essential to follow the instructions carefully and avoid overlapping or applying too much bleach to one area.
Processing the Bleach
The bleach is left to process for a specified amount of time, usually between 20-45 minutes. The processing time will depend on the type of bleach, the condition of the hair, and the desired result. It is essential to monitor the processing time carefully, as over-processing can cause damage to the hair.
After the Bleaching Process
After the bleaching process, it is essential to follow a post-bleach care routine to maintain the health and integrity of the hair. This includes:
Toning the Hair
Toning the hair is an essential step in achieving the perfect shade. A toner is applied to the hair to neutralize any unwanted tones and enhance the desired color. There are several types of toners available, including purple-based toners for ash or beige shades and gold-based toners for warm or honey shades.
Maintaining Hair Health
Maintaining hair health after bleaching is critical. This includes using moisturizing shampoos and conditioners, deep conditioning treatments, and hair masks. It is also essential to avoid using heat styling tools, as they can cause further damage to the hair.

What are the risks associated with bleaching dyed black hair?
Bleaching dyed black hair can be a risky process, as it requires the use of strong chemicals to lift the color out of the hair. One of the main risks is damage to the hair, including dryness, brittleness, and breakage. This is because the bleach penetrates the hair shaft and breaks down the pigment, causing the hair to become weakened. Additionally, over-bleaching can cause the hair to become over-processed, leading to a range of problems, including frizz, unmanageability, and even hair loss.
To minimize the risks associated with bleaching dyed black hair, it’s essential to take a gradual and gentle approach. This may involve using a gentle bleach or a semi-permanent color remover, rather than a strong permanent bleach. It’s also crucial to follow the instructions carefully and to perform a strand test before applying the bleach to the entire head. This will help to ensure that the desired results are achieved without causing damage to the hair. Furthermore, using a good quality conditioner and moisturizer after the bleaching process can help to restore the hair’s natural moisture and minimize the risk of damage.
How do I prepare my dyed black hair for bleaching?
Preparing your dyed black hair for bleaching is an essential step in achieving the perfect shade. Before bleaching, it’s crucial to wash your hair with a clarifying shampoo to remove any product buildup or impurities that may interfere with the bleaching process. You should also avoid using any heat styling tools or chemical treatments for at least a week before bleaching, as these can cause damage to the hair and make it more prone to breakage. Additionally, it’s a good idea to get a trim or haircut to remove any split ends or damaged hair, as this will help to prevent further breakage and ensure that the bleaching process is as even as possible.
It’s also important to consider the condition of your hair before bleaching. If your hair is already damaged or over-processed, it may be more difficult to achieve the desired results. In this case, it may be necessary to use a gentler bleach or to take a more gradual approach to lifting the color. A hair care professional can help you to assess the condition of your hair and recommend the best course of action. They can also provide guidance on how to prepare your hair for bleaching, including the use of pre-bleach treatments or conditioners to help to open up the hair cuticle and allow the bleach to penetrate more evenly.
What is the best bleach to use on dyed black hair?
The best bleach to use on dyed black hair depends on a range of factors, including the condition of the hair, the desired shade, and the individual’s hair type. For most people, a high-lift bleach is the best option, as it is designed to lift the color out of the hair quickly and efficiently. However, high-lift bleaches can be harsh on the hair, so it’s essential to use a gentle and moisturizing conditioner after the bleaching process to help to restore the hair’s natural moisture.
There are many different types of bleach available, including powder bleach, cream bleach, and oil bleach. Powder bleach is a popular option, as it is easy to mix and apply, and it can be used to achieve a range of different shades. Cream bleach is another popular option, as it is gentler on the hair and can be used to achieve a more subtle, natural-looking color. Oil bleach is a less common option, but it can be used to achieve a range of different shades, from subtle, natural-looking colors to bold, vibrant colors. It’s essential to follow the instructions carefully and to perform a strand test before applying the bleach to the entire head.
How long does it take to bleach dyed black hair?
The time it takes to bleach dyed black hair depends on a range of factors, including the condition of the hair, the desired shade, and the individual’s hair type.
