Bleaching hair can be an exciting and transformative process, allowing individuals to express themselves creatively through color. However, it’s essential to understand the implications and risks associated with hair bleaching, especially when using products like a 20-volume developer. In this comprehensive article, we’ll explore whether you can safely bleach your hair twice using 20 developer, the science behind it, and tips for achieving the best results while maintaining healthy hair.
Understanding Hair Bleaching
Before diving into the specifics of using 20 developer for bleaching, let’s first understand what hair bleaching entails.
What is Hair Bleaching?
Hair bleaching is a chemical process that lifts the natural color of your hair. This is accomplished using a combination of hydrogen peroxide and ammonia, which opens up the hair cuticle and removes its natural pigment. The result is a lighter shade of hair, which can range from subtle highlights to a dramatic platinum blonde, depending on your hair’s initial color and condition.
What is Developer?
Developer, also known as oxidizing agent, is an essential component in the hair bleaching process. It comes in different volumes, which indicate the level of hydrogen peroxide they contain. The higher the volume, the more lift it provides to the hair color.
- 20 Volume Developer: Contains 6% hydrogen peroxide and is commonly used for achieving up to two levels of lift. It’s suitable for lighter hair shades or for those with fine, delicate hair.
- 30 and 40 Volume Developers: These have higher concentrations of hydrogen peroxide and can lift hair color more aggressively. They are often recommended for those looking to achieve dramatic color changes quickly.
Can You Bleach Your Hair Twice with 20 Developer?
The short answer to this question is yes, you can bleach your hair twice with 20 developer. However, there are several factors to consider before proceeding with this process.
Factors to Consider Before Bleaching Twice
-
Hair Health: The most crucial aspect to assess before bleaching is the overall health of your hair. If your hair is already damaged, over-bleaching can lead to severe breakage and dryness.
-
Color Goals: Consider what color you aim to achieve. If your goal is to go from dark brown to blonde, you may require multiple sessions. While 20 developer is gentle, be prepared for the possibility that you may need to use a stronger developer later on for further lift.
How to Safely Bleach Your Hair Twice
If you decide to go ahead with bleaching your hair twice using 20 developer, it’s essential to do so safely. Here are some steps you can follow:
Step 1: Assess Your Hair Condition
Before applying bleach, conduct a strand test. Take a small section of hair and apply the bleach to see how your hair reacts. If the strand shows signs of excessive damage or breakage, reconsider your bleaching plan.
Step 2: Prepare for Bleaching
-
Gather Your Supplies: You will need bleach powder, 20-volume developer, gloves, a mixing bowl, tint brush, and a timer.
-
Pre-Apply Treatments: Consider using a bond builder or hair protective treatment before bleaching. Products like Olaplex can help reduce damage during the bleaching process.
Step 3: First Bleach Application
- Mix your bleach powder and 20-volume developer according to the manufacturer’s instructions.
- Section your hair into manageable parts. Start from the ends, working your way up to the roots, as roots tend to lift faster due to the heat from your scalp.
- Apply the mixture evenly and thoroughly, using the tint brush, and ensure full saturation for consistent results.
- Set a timer based on the recommended processing time (typically around 30 to 45 minutes).
Step 4: Rinse and Assess
After the first application, rinse your hair thoroughly with lukewarm water. Follow up with a deep conditioning treatment to help restore moisture. Take this time to assess the lift you’ve achieved and your hair’s condition.
Step 5: Wait Before Second Application
If you plan to bleach your hair a second time, give your hair a break. Wait at least a week, and use hydrating hair masks to restore moisture and strength.
Step 6: Second Bleach Application
Follow the same steps as the first application for the second bleaching. Make sure to monitor your hair closely for any signs of damage.
The Risks of Bleaching Your Hair
While bleaching can produce stunning results, it also carries risks, particularly when done multiple times. Here are some of the common risks associated with bleaching hair:
Damage to Hair Structure
Repeated bleaching can lead to irreversible damage, especially if proper techniques and care aren’t followed. Visible signs of damage include:
- Dryness and brittleness
- Split ends
- Breakage
Scalp Sensitivity
The chemical components in bleach can irritate the scalp. If you experience burning, excessive tingling, or discomfort, it’s crucial to rinse the product out immediately.
Uneven Color Results
If not done correctly, bleaching twice can result in uneven color distribution. This is often seen as blotchiness or patchiness in the final appearance.
Aftercare: Maintaining Healthy Hair Post-Bleach
After successfully bleaching your hair, maintaining its health is of utmost importance. Here are some aftercare tips:
1. Deep Conditioning Treatments
Invest in high-quality, hydrating hair masks. Look for products that contain proteins and moisturizers to replenish moisture lost during bleaching.
2. Limit Heat Styling
Heat can exacerbate damage to bleached hair. Limit the use of hairdryers, straighteners, and curling irons, or use heat protectant sprays if necessary.
3. Regular Trims
Trim your hair every 6-8 weeks to remove split ends and encourage healthier growth. This helps to maintain the integrity of your hair.
4. Use Color-Safe Products
Shampoos and conditioners specifically designed for color-treated hair help in preserving vibrancy while nourishing the hair strands.
Conclusion
In summary, you can bleach your hair twice with 20 developer, but it’s vital to approach the process with caution. Understanding the potential risks and following the recommended steps for safe bleaching can make a significant difference in achieving beautiful and healthy results. Always prioritize your hair health by conducting thorough assessments, utilizing protective treatments, and adhering to an effective aftercare routine.
By following these guidelines, you can enjoy the transformation that comes with lighter hair while minimizing damage and ensuring your locks remain vibrant and healthy. Happy bleaching!
Can I bleach my hair twice with 20 developer in one session?
Yes, it is possible to bleach your hair twice in one session using 20 volume developer; however, it is not generally recommended. Bleaching is a chemical process that can weaken or damage the hair. Attempting to bleach twice in a single session may lead to severe dryness, breakage, or unwanted results. It is essential to assess your hair’s current condition and level of damage before making a decision.
If you choose to go ahead with this method, ensure that you closely monitor your hair throughout the process. Perform a strand test to evaluate how your hair responds to the bleach and developer. This will help you gauge whether your hair can tolerate two applications in one sitting. Always prioritize the health of your hair to prevent long-term damage.
How does 20 developer affect the bleaching process?
20 volume developer is considered a mild option when it comes to hair bleaching. It has the capability to lighten your hair by about 1.5 to 2 levels, making it a good choice for those looking for subtle changes or for lifting color. The developer’s gentler formula can be less damaging than higher volumes, which makes it a popular choice for individuals with sensitive or fine hair.
However, results may vary based on your hair type and the existing color. Darker hair, especially, might not lighten effectively with 20 volume developer alone, and multiple applications may be necessary, which can increase the risk of damage. Therefore, it’s vital to understand your hair’s porosity and condition before proceeding with any bleaching treatment.
How long should I wait between bleaching sessions?
If you’re considering bleaching your hair again, waiting at least 2 to 4 weeks between sessions is generally recommended. This allows your hair to recover from the harsh chemicals and minimizes the risk of significant damage. Hair undergoes stress during the bleaching process, and giving it time to recuperate can help maintain its health and appearance.
In addition to waiting, during this period, focus on deep conditioning treatments and using nourishing hair products to restore moisture and strength to your hair. Monitor its health closely; if you notice significant damage or dryness, it may be wise to extend the waiting period before bleaching again.
Can I use 20 developer on damaged hair?
Using 20 volume developer on damaged hair is not advisable. While this developer is less harsh compared to higher volumes, if your hair is already compromised, the bleaching process could exacerbate the existing damage. The chemicals in the developer can strip essential moisture from the hair, leading to increased fragility and breakage.
Before using any bleaching agent, assess your hair’s condition and consider treatments to restore health. Deep conditioning masks, protein treatments, or even consulting with a professional stylist can provide insight into whether your hair is ready for more chemical processing. Always prioritize hair health to avoid undesirable results.
What should I do if my hair turns orange after bleaching?
If your hair turns orange after bleaching, it’s often due to underlying pigments in your hair that haven’t been lifted completely, especially if you are using 20 volume developer. To neutralize the orange tones, you can use a purple or blue toner, which helps counteract the warm hues. Applying a toner can help achieve a more balanced, cooler blonde shade.
However, it’s important to wait at least a week or two after your initial bleaching session before applying toner. This waiting period allows your hair to recover from the initial chemical process and minimizes further damage. If you’re unsure about the toner application, consider consulting a professional stylist for guidance.
What are the risks of bleaching hair multiple times?
Bleaching hair multiple times can significantly increase the risk of damage, including dryness, brittleness, and breakage. Each time you bleach, the process strips moisture from the hair shaft and can alter its structural integrity. The more you expose your hair to these chemicals, the more likely you are to experience negative effects, which can lead to difficulty styling or maintaining your hair.
Additionally, over-processing can lead to uneven results and unwanted colors. If your hair is already compromised, repeated bleaching can result in a “bleach band” effect, where certain sections are lighter than others, creating an unattractive look. It’s always best to be cautious and prioritize hair health when considering multiple bleaching sessions.
Should I consult a professional before bleaching my hair?
Yes, consulting a professional before bleaching your hair is highly recommended, especially if you are new to the process or have concerns about your hair’s condition. A qualified stylist can provide valuable insights on the appropriate developer strength to use, the best techniques for your hair type, and whether your hair can adequately handle bleach at all.
Additionally, a stylist can conduct tests to determine your hair’s porosity and overall health, ensuring that the bleaching process is tailored to suit your needs. Their expertise can help you avoid possible pitfalls and achieve the desired results while minimizing damage. When in doubt, investing in professional advice can save time, money, and hair health in the long run.
