How Long Should The Bleach Stay On The Hair With 20 Volume Developer?
The amount of time that bleach should stay on the hair with 20 volume developer depends on several factors, including the hair’s natural color, texture, and desired level of lightening. Generally, leaving the bleach on for about 20-45 minutes is common. However, it is crucial to conduct a strand test before applying the bleach to the entire head to determine the processing time that achieves the desired result without causing excessive damage to the hair.
What Is A 20 Volume Developer?
A “volume” in hairdressing refers to the intensity or concentration of hydrogen peroxide in a developer solution. Volume developers are frequently used in hair treatments such as bleaching, dyeing, and perming.
20 volume developer, often known as 20 vol or 6% peroxide, is a developer solution containing 6% hydrogen peroxide. It is a moderate-strength developer that is frequently used for raising or lightening hair.
In this case, “volume” refers to the amount of oxygen generated by hydrogen peroxide during the chemical reaction. When 20 volume developer is used with bleach or hair color, it releases enough oxygen to lighten the hair up to two levels or tones.In comparison to smaller volume developers containing 3% peroxide, such as 10 volume, 20 volume developer is somewhat stronger and may raise the hair more effectively. It is, however, still considered a gentle alternative and is often advised for lightening existing blonde or lighter hair tones or for adding delicate highlights to darker hair.
The Common Types Of Bleach Developers
The choice of developer volume in hair coloring depends on the desired result and the starting level of your hair. A 20-volume developer is commonly used to achieve a moderate lift or coverage when coloring the hair. Here are some general guidelines for choosing a developer volume:
Common types of bleach developers
- 10 Volume (3%): This developer is used for deposit-only or tone-on-tone color. It doesn’t provide much lift but is suitable for darker shades or when you want to darken your hair.
- 20 Volume (6%): This developer is the most commonly used strength. It provides moderate lift and is suitable for covering gray hair or lightening hair up to two shades.
- 30 Volume (9%): This developer provides a higher lift and is suitable for lightening the hair by up to three shades. It is commonly used for achieving lighter shades or when dealing with resistant hair.
- 40 Volume (12%): This developer provides the highest lift and is used when you need to lighten the hair by more than three shades. It should be used with caution as it can be more damaging to the hair.
You can also refer to the information presented in the form of a comparison table below for easier understanding:
Trying on bleach hair with volume developer
| Developer Volume | Strength | Lift Capability | Common Uses |
| 10 Volume (3%) | Low | Minimal | Deposit-only or tone-on-tone color, darkening hair |
| 20 Volume (6%) | Moderate | Up to 2 shades | Covering gray hair, lightening hair moderately |
| 30 Volume (9%) | High | Up to 3 shades | Achieving lighter shades, dealing with resistant hair |
| 40 Volume (12%) | Very High | More than 3 shades | Significantly lightening hair (caution: potential for more damage) |
Will 20 Volume Developers Lighten Hair Without Bleach?
No, a 20 volume developer alone will not lighten hair without bleach. Bleach is the primary agent responsible for lightening the hair’s natural pigment. The role of the developer is to activate and facilitate the lightening process by oxidizing the bleach.
In the case of a 20 volume developer, it contains a 6% concentration of hydrogen peroxide, which is not strong enough to significantly lighten the hair on its own. It is typically used with bleach powder to achieve desired lightening results.If you want to lighten your hair without using bleach, you would need to explore alternative methods such as high-lift hair dyes or hair lightening products specifically formulated to work without bleach.
A Reasonable Hair Lightening Time With 20 Volume Developers
The recommended duration for leaving bleach with 20 Volume Developer on the hair for around 10 to 45 minutes. However, the exact timing for leaving bleach in your hair with a 20-volume developer depends on various factors, including your hair type and color. Here’s a brief guide for different scenarios:
- Fine Hair: Allow the bleach to sit for 20-30 minutes. Fine hair tends to lift faster, so it’s critical to keep an eye on the process to avoid overprocessing.
- Coarse Hair: Increase the processing time to 30-45 minutes. Because coarse hair takes longer to lift, a somewhat longer period is required.
- Blonde Hair: If your hair is already blonde, you may just need to let the bleach on for around 10-15 minutes. Blondes have less pigment to remove, and overprocessing can do significant harm.
- Dark Hair: Darker hair takes longer for the bleach to lift the color. Begin by letting the bleach on for 30-45 minutes, but monitor the process closely. If you want a lighter effect, you may need to repeat the process.
- Damaged Hair: If your hair is already damaged or delicate, you should proceed with caution while bleaching. Reduce the processing time to 10-20 minutes to avoid additional harm.
Remember, these timeframes are general guidelines, and it’s essential to assess your hair’s progress during the bleaching process. Regularly check the color and condition of your hair to ensure you achieve the desired lift without causing excessive damage. If uncertain or inexperienced, it’s recommended to consult a professional hairstylist for assistance.

If you’re unsure, it’s best to consult a professional hairstylist for personalized advice.
2. Can I use 20 Volume Developer to lighten dark hair to a blonde shade?
While 20 Volume developer can help lighten dark hair, it may not be sufficient to achieve a blonde shade on its own, especially if your starting color is significantly darker. In most cases, when aiming for a blonde shade from dark hair, it is necessary to use bleach along with a higher volume developer, such as 30 or 40 Volume, to achieve the desired lightening effect.

Keep in mind that bleach will continue to lighten the hair as long as it is left on, so be cautious not to exceed the desired lightness level.
7. How should I care for my hair after bleaching with 20 volume developer?
After bleaching with 20 volume developer, it’s crucial to provide your hair with extra care and moisture. Use sulfate-free shampoos and conditioners specifically formulated for color-treated or bleached hair. Deep conditioning treatments, hair masks, and leave-in conditioners can also help restore moisture and nourishment. Additionally, minimize the use of heat styling tools and protect your hair from excessive sun exposure to prevent further damage.
8. Should I shampoo after bleaching?
Yes, it’s necessary to shampoo your hair after bleaching to remove any residual bleach and prevent yellow tones. However, bleaching weakens the hair, so use a moisturizing conditioner afterward and incorporate deep conditioning treatments to nourish and protect your hair.
9. Should I tone my hair after bleaching it?
Whether or not to tone your hair after bleaching depends on your desired result. If you want to achieve a classic blonde look or eliminate brassy hues, toning can be beneficial. Consult with a professional stylist to choose the right toner shade and ensure the best outcome without compromising your hair’s condition.
10. How soon after bleaching hair can you bleach again?
Because the hair cuticle stays open, you may technically bleach your hair less than a day after the initial bleaching. However, it’s best to wait a few days for your hair to recuperate from the rigorous bleaching procedure and limit any damage. Bleaching your hair too regularly might be harmful to its health.
