How Long to Leave Bleach in Hair: Duration for Different Volume Levels
For 40 Volume bleach, the recommended time to leave it on is between 10-20 minutes.
40 Volume: 10-20 minutes
Using a 40 volume developer for bleaching the hair is indeed a strong solution, giving intense lightening results. This intense strength makes it crucial to limit its contact time with your hair; typically, 10 to 20 minutes should suffice.
If left longer than this, you’re venturing into potentially damaging territory that could lead to breakage and irritation. Keep in mind that if the desired color isn’t achieved within 20 minutes, instead of leaving the bleach on longer, try reapplying at another time.
Despite being powerful, over exposure can be risky.
30 Volume: 20-30 minutes
For 30 volume bleach, you should leave it in your hair for around 20 to 30 minutes. This is the recommended duration to achieve the desired lightening effect without causing excessive damage.
Remember, leaving it on for too long can lead to hair breakage and scalp irritation. It’s important to follow these guidelines and not exceed the recommended time to keep your hair healthy and beautiful.
20 Volume: 30-40 minutes
For 20 volume bleach, the recommended duration for leaving it in your hair is between 30 to 40 minutes. This strength of bleach provides a medium level of lightening and can help achieve a noticeable color change.
However, it’s important not to exceed the maximum recommended time to prevent any potential damage to your hair and scalp. Remember, everyone’s hair is different, so it’s essential to monitor the process closely and adjust the timing accordingly for personalized results.
10 Volume: 45 minutes
For 10 volume bleach, you should leave it in your hair for a maximum of 45 minutes. This volume is less strong than higher levels, so it takes longer to lighten the hair. However, be cautious not to exceed the recommended time as leaving it on for too long can lead to damage and unwanted side effects.
Remember to always follow the instructions provided with the bleach product and do a patch test before applying it all over your hair.

Hair damage
Leaving bleach in your hair for too long can cause serious damage. The maximum recommended time is 30 minutes to avoid any negative effects. If you’re using 40 volume bleach, it’s sufficient to leave it in your hair for about 20 minutes.
Going beyond this time limit can result in harm to both your hair and scalp. Remember that everyone’s hair is different, so adjust the timing based on your own needs. Lastly, be cautious as leaving a high-volume developer like 40 volume on your hair for more than the recommended time can lead to significant damage.
Scalp irritation
Leaving bleach on your hair for too long can lead to scalp irritation. This occurs when the harsh chemicals in the bleach come into direct contact with your scalp, causing redness, itching, and discomfort.
To prevent scalp irritation, it is important to follow the recommended time guidelines for leaving bleach in your hair. For 40 volume bleach, you should leave it in for around 20 minutes at most.
Exceeding this time can increase the risk of scalp irritation and other negative side effects. It’s essential to prioritize the health of your scalp during the bleaching process to achieve beautiful results without any discomfort or damage.
Hair breakage
Leaving bleach on your hair for too long can result in hair breakage. This occurs when the bleach strips away the natural oils and proteins that keep your strands strong and healthy.
The longer you leave the bleach in, the more damage it can cause to your hair fibers, leading to breakage and even split ends. To prevent this from happening, it is crucial to follow the recommended time guidelines for leaving bleach on your hair.
For 40 volume bleach, it is best to leave it in for about 20 minutes. Remember, exceeding this time can increase the risk of hair breakage and other negative side effects.
Factors to Consider for Bleaching Hair
Consider your hair type, starting color, desired outcome, type of developer, and bleaching frequency when determining how long to leave bleach in your hair.
Hair type
Different hair types can have varying levels of sensitivity and response to bleach. Understanding your hair type is important when determining how long to leave bleach in your hair.
Fine or thin hair generally processes bleach faster than thick or coarse hair. This means that if you have fine hair, you may want to reduce the recommended processing time slightly to avoid over-bleaching.
On the other hand, if you have thick or coarse hair, you might need to extend the processing time slightly to achieve the desired level of lightening. It’s also important to remember that leaving bleach on any type of hair for too long can result in damage, so it’s best to follow the recommended time limits and monitor your hair closely during the process.
When considering how long to leave bleach in your hair based on its type, keep in mind that these recommendations are general guidelines and may vary based on individual factors such as starting color and desired outcome.
Starting hair color
To determine how long to leave bleach in your hair, you should consider your starting hair color. If you have darker hair, it may take longer for the bleach to lighten it compared to lighter hair colors.
For example, if you have black or brown hair, it might require a longer processing time than if you have blonde or light brown hair. The starting color of your hair plays a significant role in how long the bleach needs to be left on for optimal results.
Keep in mind that leaving bleach on for too long can lead to damage, so it’s important to follow the recommended guidelines and not exceed the maximum recommended time.
Desired outcome
To achieve your desired outcome when bleaching your hair, it is important to consider factors such as your starting hair color, the type of developer you are using, and the intensity of lightening you want to achieve.
It’s crucial to follow recommended processing times for bleach and not exceed them to avoid damage. For example, if you are using 40 volume bleach, leaving it in your hair for a maximum of 20 minutes should give you the desired results.
Remember that everyone’s hair is different, so it’s essential to monitor the process closely and adjust accordingly.
Type of developer
The type of developer you choose can significantly impact the results of your hair bleaching process. When it comes to bleaching, developers are available in different volumes, such as 10, 20, 30, and 40.
The volume refers to the strength of the developer and determines how much lightening or lifting power it has. For example, a 40-volume developer is stronger than a 20-volume one. It’s important to note that higher volume developers should be used with caution as they can cause more damage to your hair if left on for too long.
To avoid potential risks and achieve desired results, it is crucial to follow the recommended time limits for each specific developer volume.
Bleaching frequency
To maintain healthy hair, it is important to consider the frequency of bleaching. Bleaching your hair too often can lead to damage and breakage. It is recommended to wait at least 4-6 weeks between bleachings to allow your hair enough time to recover.
This will help minimize the risk of harming your strands and keep them in better condition. Remember, patience is key when it comes to achieving your desired hair color while keeping your locks healthy and strong.
Precautions and Tips for Bleaching Hair
Perform a patch test on a small section of hair to check for any allergic reactions or unexpected results beforehand.
Perform a patch test
Before applying bleach to your hair, it is crucial to perform a patch test. This simple step helps prevent any potential allergic reactions or adverse effects. To do a patch test, mix a small amount of the bleach solution and apply it on a small section of hair behind your ear or on your inner arm.
Leave it for the recommended time and then rinse thoroughly. Keep an eye out for any redness, itching, or irritation in the next 24-48 hours. If you experience any negative reactions, do not proceed with bleaching your entire head of hair.
It’s better to be safe than sorry when it comes to protecting both your scalp and overall hair health.
Read directions carefully
To ensure a successful and safe hair bleaching experience, it is crucial that you take the time to carefully read and follow the instructions provided with your bleach product. These directions are specifically designed to help you achieve optimal results while minimizing any potential damage or risks.
Pay attention to important details such as recommended processing times, application techniques, and any precautions or warnings mentioned. By reading and understanding the directions before starting the bleaching process, you can avoid any unnecessary mistakes or complications that may arise from improper use of the product.
Take care of hair post-bleaching
After bleaching your hair, it’s important to take good care of it to minimize any damage. Start by using a gentle shampoo and conditioner specifically designed for color-treated hair.
These products will help nourish and hydrate your hair, preventing dryness and breakage. Avoid heat styling tools like flat irons or curling irons for a few days to give your hair a chance to recover.
Instead, opt for air drying or using heat-free styling methods like braiding or twisting. Regularly deep condition your hair to restore moisture and improve its overall health. Lastly, protect your newly bleached locks from the sun by wearing a hat or applying a leave-in conditioner with UV protection before heading outside.
Pros and cons of professional salon vs. at-home bleaching
When it comes to bleaching your hair, you have two primary choices: at a professional salon, or DIY at home. Each option comes with its own set of advantages and disadvantages.
| Professional Salon Bleaching | At-Home Bleaching | |
|---|---|---|
| Pros | Professionals have extensive knowledge of hair types and bleach volumes, ensuring less risk of scalp irritation or hair damage. They also have experience with different hair colors, which can lead to more predictable results. | At-home bleaching kits are usually more affordable than salon services. They also offer the convenience of performing the procedure according to your own schedule. |
| Cons | Salon services can be quite expensive, especially for maintaining a bleached look. Also, appointments may not always fit into your schedule. | While cheaper, at-home bleaching kits come with a risk of hair and scalp damage if left for too long, especially when using a 40 volume developer. Achieving the desired hair color may also be challenging without professional guidance. |
Always keep in mind that the maximum recommended time for leaving bleach in hair is 30 minutes. Over-bleaching can lead to severe hair damage, especially with a 40 volume developer, which should be left in hair for a maximum of 20 minutes. It’s always essential to fine-tune the bleaching process based on your individual needs, whether you choose a salon or at-home bleaching.
