Can You Put Bleach on Already Bleached Hair? Understanding the Risks and Benefits

Bleaching hair can be a transformative process, changing one’s appearance dramatically. However, it’s a chemical treatment that must be approached with caution, especially when considering applying bleach to hair that has already undergone this process. The question of whether you can put bleach on already bleached hair is complex and depends on several factors, including the current condition of your hair, the time elapsed since the last bleaching, and your desired outcome. In this article, we will delve into the world of hair bleaching, exploring the risks, benefits, and best practices for applying bleach to previously bleached hair.

Understanding Hair Bleaching

Hair bleaching is a process that involves using chemicals to strip the hair of its pigment, resulting in a lighter color. This process can be damaging to the hair, as it involves breaking down the hair’s cuticle to reach the pigment inside. The extent of the damage often depends on the bleach used, the method of application, and the condition of the hair before bleaching. When hair is bleached, the cuticle is lifted, and the cortex, where the pigment resides, is accessed to remove or alter the color. This can leave the hair feeling dry, looking dull, and being more prone to breakage.

The Risks of Re-Bleaching Hair

Applying bleach to already bleached hair can increase the risk of significant damage. Over-bleaching can lead to hair that becomes brittle, prone to breakage, and develops an unwanted porous texture. The risks include:

• Increased porosity: Hair that has been bleached multiple times can become highly porous, leading to difficulty in achieving and maintaining the desired color and health of the hair.
• Breakage: Over-bleaching puts immense stress on the hair shaft, leading to weakness and breakage.
• Dryness: Repeated bleaching can strip the hair of its natural oils, leading to dryness and dullness.

Considerations Before Re-Bleaching

Before deciding to put bleach on already bleached hair, several factors must be considered. It’s essential to assess the current condition of your hair, including its porosity, elasticity, and moisture levels. Hair that is already compromised may not withstand another bleaching process. Furthermore, the time since the last bleaching is crucial. Generally, it’s recommended to wait a significant amount of time before re-bleaching to allow the hair to recover from the previous treatment.

Safe Practices for Re-Bleaching Hair

If you still wish to bleach your hair again, there are ways to minimize the risks. Using a lower volume developer and choosing a gentler bleach can help reduce damage. Additionally, performing a strand test before applying bleach to your entire head can give you an idea of how your hair will react. This test can help you avoid over-processing and reduce the risk of severe damage.

Pre-Bleach Preparation

Preparation is key when it comes to bleaching hair that has been previously bleached. Treating your hair with deep conditioning treatments and protein masks in the weeks leading up to the bleaching process can help strengthen the hair and reduce the risk of breakage. Using products that are rich in moisturizers and proteins can help repair and protect the hair.

Nourishing Treatments

Incorporating nourishing treatments into your hair care routine before re-bleaching can make a significant difference. Olives oil, coconut oil, and argan oil are excellent for moisturizing, while products containing keratin and collagen can help repair and strengthen the hair. Regular trims can also help remove split ends and prevent further damage.

Alternatives to Re-Bleaching

Given the risks associated with re-bleaching hair, it’s worth considering alternatives that can achieve your desired color without the potential for significant damage. Toning can be a great option for making slight adjustments to the color of your hair without the need for bleach. Additionally, highlighting or lowlighting can add dimension and interest to your hair without fully bleaching it.

Color Depositing Treatments

Color depositing treatments can be used to enhance or change the color of your hair without bleach. These treatments work by depositing color onto the hair shaft rather than lifting it, which can be less damaging. They are an excellent option for those looking to maintain or slightly alter their current color without the risks associated with bleaching.

Conclusion

While it is technically possible to put bleach on already bleached hair, it’s a process that requires careful consideration and preparation. Understanding the risks and taking steps to minimize them is crucial for maintaining the health and integrity of your hair. Whether you decide to re-bleach or explore alternative options, prioritizing your hair’s health through regular nourishing treatments and protective care can make all the difference. Always consult with a professional hairstylist before making significant changes to your hair, especially when it comes to bleach, to ensure the best possible outcome.

Can I apply bleach on already bleached hair to achieve a lighter shade?

Applying bleach on already bleached hair is possible, but it’s crucial to exercise caution. Repeated bleaching can cause significant damage to your hair, especially if done incorrectly or too frequently. The process of bleaching removes the natural pigment from your hair, and with each application, your hair becomes more prone to breakage and dryness. If you still want to attempt to achieve a lighter shade, consider consulting a professional hairstylist who can assess the condition of your hair and provide personalized guidance.

Before re-applying bleach, it’s essential to consider the current state of your hair. If your hair is already damaged, over-processed, or shows signs of breakage, it’s not recommended to apply more bleach. Instead, focus on nourishing and repairing your hair with moisturizing treatments and protein-based products. If your hair is in good condition, you can proceed with caution, but be sure to use a lower volume developer and follow a gentler application process to minimize further damage. Additionally, consider using alternative lightening methods, such as balayage or highlights, to achieve a lighter shade without over-processing your entire head of hair.

What are the potential risks associated with putting bleach on already bleached hair?

The potential risks associated with applying bleach on already bleached hair are numerous. One of the most significant risks is over-processing, which can cause your hair to become brittle, fragile, and prone to breakage. Repeated exposure to bleach can also lead to hair porosity issues, where the hair cuticle becomes lifted, causing your hair to lose its natural shine and become more susceptible to damage. Furthermore, excessive bleaching can result in unwanted warm tones, such as brassy or yellow hues, which can be challenging to correct.

To minimize the risks, it’s essential to assess the current condition of your hair and proceed with caution. Consider getting a hair health check with a professional stylist who can evaluate the porosity, elasticity, and overall condition of your hair. They can help you determine the best course of action and recommend a suitable treatment plan to achieve your desired results while minimizing damage. If you do decide to re-apply bleach, be sure to use a gentle, high-quality product and follow the instructions carefully to avoid over-processing or further damaging your hair.

How can I determine if my already bleached hair can withstand another bleach application?

To determine if your already bleached hair can withstand another bleach application, start by assessing its current condition. Check for signs of damage, such as split ends, breakage, or frizz. If your hair appears healthy, with minimal damage, it may be able to withstand another bleach application. However, if your hair shows significant signs of damage or over-processing, it’s best to avoid re-applying bleach and focus on nourishing and repairing your hair instead.

A hair strand test can also help you determine the condition of your hair and its ability to withstand further bleaching. Take a small section of hair and apply the bleach mixture, following the recommended processing time. If the hair strand appears damaged, breaks, or shows signs of over-processing, it’s a clear indication that your hair is not suitable for another bleach application. In this case, consider alternative lightening methods or focus on repairing and nourishing your hair with gentle, moisturizing treatments.

Can I use a lower volume developer to minimize damage when re-applying bleach on already bleached hair?

Using a lower volume developer is a good strategy to minimize damage when re-applying bleach on already bleached hair. A lower volume developer, typically 10 volume or lower, will process the hair more gently, reducing the risk of over-processing and damage. However, it’s essential to note that using a lower volume developer may also slow down the lightening process, requiring more time and patience to achieve the desired results.

When using a lower volume developer, it’s crucial to follow the instructions carefully and monitor the processing time closely. Be prepared to adjust the processing time according to your hair’s response to the bleach mixture. Additionally, consider using a pre-bleach treatment or a bonding agent to help minimize damage and protect your hair during the bleaching process. These products can help repair and strengthen your hair, reducing the risk of breakage and over-processing.

What are the benefits of re-applying bleach on already bleached hair, and are they worth the risks?

The benefits of re-applying bleach on already bleached hair include achieving a lighter shade, removing warm tones, and correcting previous color applications. If done correctly, re-bleaching can also help to create a more even, uniform color distribution. However, these benefits must be weighed against the potential risks, including damage, over-processing, and breakage. In many cases, the risks associated with re-bleaching may outweigh the benefits, especially if your hair is already damaged or over-processed.

To determine whether the benefits are worth the risks, consider your hair goals and priorities. If achieving a lighter shade is essential, and you’re willing to take the necessary precautions to minimize damage, re-bleaching may be a viable option. However, if your hair is already damaged or you’re concerned about preserving its health, it’s best to explore alternative lightening methods or focus on nourishing and repairing your hair. Consult with a professional stylist to discuss your options and determine the best course of action for your hair.

How can I care for my hair after re-applying bleach to minimize damage and promote recovery?

After re-applying bleach, it’s essential to focus on nourishing and repairing your hair to minimize damage and promote recovery. Start by using gentle, sulfate-free shampoo and conditioner, and consider a moisturizing mask or deep conditioning treatment to help repair and hydrate your hair. Avoid using heat styling tools or excessive heat, as this can further damage your hair and slow down the recovery process.

In addition to using gentle hair care products, consider incorporating hair masks and treatments that contain ingredients such as argan oil, coconut oil, or keratin. These ingredients can help to nourish, moisturize, and repair your hair, reducing the risk of breakage and damage. Also, be gentle when combing or brushing your hair, avoiding excessive tension or tugging, which can cause further damage. With proper care and attention, your hair can recover from the bleaching process, and you can achieve healthy, vibrant-looking hair that looks and feels great.
