Hair developer is a creamy rinse-out product that helps open up your hair’s cuticle so color can be lifted or deposited.

When lightening hair, developer is often used with bleach, a hair dye cream or liquid, or another type of lightener. Yet, curious folks all over wonder whether they can lighten their hair with just developer.

Will developer lighten hair? In this article, we’ll explore just that. 

Can I Lighten My Hair with Just Developer?

You can lighten your hair with just developer. Developer contains hydrogen peroxide, which lightens your hair by penetrating the cortex and destroying the pigments inside. The stronger the concentration of developer, the more color-lifting hydrogen peroxide it contains.

Developer-only lightening is useful for gradually lightening your hair over a long period of time or for lightening your hair by one or two shades. However, it’s not recommended for lightening your hair by more than two shades, as it may not be as effective as using bleach or other hair lighteners.

When Developer-Only Lightening Is Useful

Developer-only lightening is useful if you are trying to gradually lighten your hair over a long period of time. It’s also beneficial if you only want to lighten your hair one or two shades from your starting hair color.

We don’t recommend using a hair developer to lighten your hair by more than two shades. For example, going from a dark brown to platinum blonde hair color will require bleaching agents.

If your hair is already damaged, the safest option is to avoid lightening it further. However, if you must lighten your hair, the developer-only method can help you avoid the extra-damaging effects of hair bleach.

HOW TO DYE YOUR HAIR WITH DEVELOPER ONLY!!!

If you’d like to ditch the bleach and lighten your hair with just developer, you should take steps to ensure you’re doing it right. Here’s how to lighten hair with just developer. 

You’ll need: 

  • Small mixing bowl
  • Gloves
  • Hair clips or ties
  • Bottle of creme developer (we recommend 20 or 30 volume developer) 
  • Dye brush
  • A timer or clock
  • Shower Cap

Directions:

  1. Choose your level of developer. Developer comes in a range of strengths that correspond to the amount of hydrogen peroxide they contain. In order to avoid unnecessary damage, you should always use the lowest concentration that will meet your needs. We recommend using a 20 or 30 volume developer.
    • 40 and 50 volume developers are extremely strong. While they’ll lighten your hair much more than the lower concentrations, they can also cause significant damage to your hair and scalp. 
    • 30 volume developer is more forgiving and will still allow you to lighten your hair by two to three levels. 
    • 20 volume developer can lighten your hair one to two levels, without causing significant damage. 
    • 10 volume developer is the weakest concentration. It isn’t strong enough to lighten your hair in one session and is usually used with deposit-only dyes. 
  2. Start with clean, slightly damp hair. 
  3. Put on your gloves, and make sure you’re wearing clothes you don’t mind getting stained. Put towels down to protect your floor and tables/countertops. 
  4. Split your hair into four even sections and secure them with hair ties or clips. 
  5. Using your dye brush, begin applying the developer to your hair. Work in small sections and apply the developer as evenly as possible. Start applying the developer around 2 inches down from your roots for a natural, low-maintenance look. 
  6. Once you finish applying the developer and your hair is fully saturated, put on the shower cap to help lock in body heat and moisture. 
  7. Set a timer and wait for 10 to 20 minutes, depending on how light you want to go. Check your hair often to see how well the color is lifting. You can let the developer sit for an extra 10 minutes if the hair color isn’t quite where you want it, but be sure not to leave it on for more than 30 minutes. 
  8. Rinse your hair thoroughly with warm water. 
  9. Follow up with shampoo and conditioner. We recommend using a deep conditioning treatment to help recover some of the moisture loss from the developer.
  10. Dry your hair to see your final hair color. Depending on the developer volume you used, and the amount of time it was left on your hair, your hair should be one to two shades lighter than when you started. 

Note: Because it’s not meant to be used alone, the results of developer-only lightening may be somewhat unpredictable. One treatment might not give you the results you want and can still result in damaged hair.

Pros and Cons of Developer-Only Lightening

While lightening your hair with just developer is possible, it’s not for everyone. The following are lists of the pros and cons associated with developer-only lightening. They will help you decide if this lightening method is right for you.

Pros

  • Less damaging than bleach. Bleaching your hair requires the use of both bleach and hydrogen peroxide. Both ingredients cause damage to your hair by opening its outermost cuticle. By skipping the bleach, you’ll be able to lighten your hair with significantly less damage.  
  • Easier process. There’s no mixing involved, which makes the lightening process easier. This translates to a lower margin of error when compared to bleach, where you have to measure and mix bleach powder and developer together. 
  • Permanent results. The hydrogen peroxide in developer will permanently lighten your hair.

Cons

  • Hair color can be brassy. Developer can reveal brassy, orangish undertones in your hair. To combat this, follow up your lightening treatment with purple shampoo or conditioner, or hair dye. 
  • Potential for damage. Even though developer-only lightening is less damaging than using bleach, it can still cause damage to your hair. Higher concentrations of developer cause more damage than lower ones, so choose a lower volume developer if you want to protect your hair.
  • Gradual effect. Developer will only lighten your hair one or two shades at a time. You should only use developer once every three to four weeks, so it can take a long time and multiple treatments to get the exact hair color you want. If you’re only looking for a slight lightening effect, this method might be perfect. But if you’re trying to go four or more levels lighter–or want to achieve a light blonde color–bleach might be the better option.

Dos and Don’ts of Developer-Only Lightening

If you’ve decided to lighten your hair with developer alone, there are some do’s and don’ts to keep in mind. These tips will help to ensure you get the results you want while avoiding unnecessary damage. 

  • Don’t let it sit too long. Developer should sit in your hair for a maximum of 30 minutes. Going over that time will increase your chances of significant hair and scalp damage. 
  • Do use protein treatments. Developer damages the cuticle of your hair and can cause it to become more porous. If your hair can tolerate it, use protein treatments once or twice a month to help rebuild the structure of your hair. 
  • Do moisturize. To combat the damage caused by the hydrogen peroxide in the developer, moisturize your hair after each wash. Deep conditioning treatments are also effective at restoring moisture to your curls
  • Don’t use developers too often. While it may take multiple treatments to achieve your desired hair color, avoid using developer more than once every 3 to 4 weeks. Using it too often can cause permanent damage to your hair.
  • Do use the correct level of developer. Using a developer that’s too strong can cause irreversible damage to your hair. Conversely, a developer that’s too weak won’t lighten your hair at all.

Can Developer Alone Lighten Your Hair?

Developer can be used by itself to lighten hair, but the strength of the developer determines its effectiveness. It’s generally only recommended for those wanting to go one or two levels lighter. When using a developer alone, the result won’t be as significant as using a hair lightener or bleach powder in combination with it.

What Can I Mix With Developer to Lighten My Hair?

It is best to mix the developer with a hair lightener or bleach powder when attempting to lighten the hair. This combination can help to achieve a more significant lightening effect on the hair. Bleach powder contains a high concentration of hydrogen peroxide, which is the primary lightening agent, while the developer works to activate the bleach powder.

What Happens if You Put Plain Developer on Your Hair?

When you apply plain developer, it can help to lighten your hair. It can still damage your hair, though not as much as when used with bleach. The developer contains hydrogen peroxide, which is a strong oxidizing agent that opens up your hair cuticles, making it easier for the hair to receive the lightening effects.

How Long Should I Leave 20 Developer in My Hair Without Bleach?

When using a 20 volume developer alone, it is recommended to leave it in the hair for up to 30 minutes. Leaving the developer in the hair for too long can cause damage or breakage. It is essential to monitor the hair’s lightening progress and wash it off as soon as the desired lightness is achieved.

Will 10 Volume Developer Lighten Hair by Itself?

A 10 volume developer alone will not lighten hair significantly, as it is designed to deposit color rather than lift it. However, it can be mixed with hair dye to create a more subtle, natural-looking hair color change. When mixed with hair dye, the developer activates the color molecules in the dye for depositing them into the hair shaft.

Will 20 Volume Developer Lighten Hair Without Bleach?

A 20 volume developer can lighten hair by up to two levels on its own, but it is still less effective than using a hair lightener or bleach powder. The 20 volume developer is most commonly used for permanent hair color and can lighten the hair’s natural color slightly.

Will 30 Volume Developer Lighten Hair Without Bleach?

A 30 volume developer can lighten hair by two or three levels on its own, but it is still not recommended to use without a hair lightener or bleach powder. The 30 volume developer is used for high-lift hair color and can lighten the hair significantly. However, leaving it on for too long causes significant damage to the hair.

Will 40 Developer Lighten Hair Without Bleach?

A 40 volume developer is the strongest developer available and can lighten hair by up to eight levels. However, it’s not recommended to use without a hair lightener or bleach powder because it significantly damages the hair. The 40 volume developer is used for extreme lightening, such as platinum blonde hair, and should be used with caution.

Can You Bleach Your Hair With Only Developer?

While you can lighten your hair with only developer, it is not the same as bleaching. Developer contains hydrogen peroxide, which can lighten your hair by one or two shades. However, the lightening effect will be less significant than when using a bleach or hair lightener combined with developer.

Bleach is a potent lightening agent that dramatically lifts hair color, making it ideal for significant color changes or achieving very light shades, such as platinum blonde. When using developer alone, the results are more subtle and better suited for those seeking a gradual or minor shift in hair color.

Can I Lighten My Pink Hair With Just Developer?

You can try to lighten your pink hair using just developer, but the results may not be as predictable or effective as bleach or a hair lightener. Developer contains hydrogen peroxide, which can help to lighten your hair by a few shades.

However, since the developer is not specifically designed to remove semi-permanent or fashion colors like pink, the outcome might not be as uniform or consistent as you would like. If you want to lighten your pink hair more effectively, it’s recommended to use a color remover specifically designed for semi-permanent hair colors or consult a professional hairstylist for guidance on the best approach.

By opting for developer-only lightening, individuals can achieve a more natural and low-maintenance look. However, it’s essential to approach this method with caution and follow the recommended guidelines to ensure the best results and avoid potential hair damage.
