Have you ever stared at a box of permanent hair dye, bewildered by the mention of “developer” and wondered what exactly it does? You’re not alone. This mysterious ingredient often leaves people feeling confused and hesitant, especially if they are new to at-home hair coloring. You might be thinking, “Can’t I just skip the developer? It seems like it might be harsh on my hair.” We’re here to clear up the confusion and give you the low-down on developer, its importance, and why it’s the secret weapon for achieving vibrant, long-lasting color.

Think of developer as the magic ingredient that makes permanent hair color actually, well, permanent. It’s the catalyst that allows the color molecules to penetrate the hair shaft and bind to the melanin, your natural hair pigment. Without developer, the color would only sit on the surface of the hair and quickly wash out. Let’s dive a little deeper into the science and understand why developer is essential for those bold, lasting color changes.
Understanding Developer and Its Role
Developer, also known as hydrogen peroxide, is a chemical that plays a crucial role in the hair coloring process. It acts as an oxidizer, lifting your natural hair color, allowing the permanent dye to deposit itself effectively.
Here’s a breakdown of how it works:
- Lifting the Hair: Developer lifts natural pigment out of the hair shaft, making space for the new color to penetrate. The developer’s strength influences how much color is lifted.
- Color Deposition: As the developer opens up the hair shaft, the permanent hair dye molecules can seep in and bind to the hair. This binding process is made possible through an oxidative reaction that creates a permanent bond between the dye molecules and the hair.
- Color Development: The process of color development doesn’t happen instantly. It requires time for the developer to oxidize the dye molecules and for the new color to fully develop. This explains why you usually have to wait a certain amount of time before rinsing out the dye.
What Happens When You Don’t Use Developer?
You might be wondering, if developer is such a key player, what happens if you skip it? Well, the answer isn’t pretty. Without the developer, the color will not achieve its full potential and will likely result in:
- Limited Color Change: The color will only deposit on the surface of the hair, leaving a temporary, patchy, or washed-out look.
- Fast Fading: The color will wash out quickly, leaving you back to your original hair color in just a few washes.
- Uneven Results: You could end up with streaks or patches of color, creating an uneven, unnatural finish.
Developer Concentration: Finding the Right Strength
Developer comes in various strengths, typically measured in volumes (volumes of hydrogen peroxide). The higher the volume, the more lifting power the developer has. Here’s a general guide to understanding developer strengths:
- 10 Volume (3% Hydrogen Peroxide): This volume is primarily used for blending colors, adding subtle shine, and highlighting.
- 20 Volume (6% Hydrogen Peroxide): A popular choice for lifting hair color up to two levels, perfect for covering grays and creating subtle shades.
- 30 Volume (9% Hydrogen Peroxide): This volume can lift hair color up to three levels, allowing for significant color changes. It’s often used for ash blonde or platinum blonde hues.
- 40 Volume (12% Hydrogen Peroxide): This high-lifting volume can lighten hair color up to four levels. It is generally used for achieving very light blonde shades and often requires professional application.

Factors to Consider When Choosing Developer
While the concept of developer may seem straightforward, choosing the right strength for your needs can be tricky. Remember, using a developer that’s too strong can damage your hair, leading to breakage and dryness. Here are some essential factors to consider:
- Your Current Hair Color: The darker your natural hair color, the stronger the volume of developer you’ll need to lift it successfully.
- Desired Hair Color: Are you aiming for a subtle change or a dramatic transformation? Your desired hair color will determine the level of lift required.
- Hair Condition: If your hair is already damaged or dry, it’s best to use a lower volume of developer to minimize further damage.
Is Developer Safe?
Developer is a chemical, and like any chemical, it can be potentially damaging if used incorrectly. Using the wrong volume, applying it for too long, or leaving it on the scalp can cause irritation, dryness, or hair breakage. That’s why it’s crucial to follow the instructions on your hair dye carefully, perform a patch test before applying it all over your hair, and consult with a professional stylist if you’re unsure about anything.
Alternative Options
For those who are concerned about the potential risks associated with developer, there are alternative options available:
- Semi-permanent hair color: These colors deposit color onto the surface of the hair and fade gradually over time. They usually don’t require developer, as they don’t lift the natural hair color.
- Toner: Toners are used to deposit color onto pre-lightened hair, adding subtle shades and refreshing the existing color. They typically use a low volume of developer for a more gentle process.
- Henna: Henna is a natural dye derived from a plant that imparts a reddish-brown hue to the hair. It doesn’t require developer and is often considered a safer alternative for those with sensitivities to chemicals.
Tips for Safe and Successful Developer Use
Here are some useful tips to ensure safe and successful developer use:
- Follow the Instructions: Always read and follow the instructions provided with your hair dye carefully. The instructions will specify the proper mixing ratio, application time, and precautions.
- Perform a Patch Test: Before applying the dye all over your hair, conduct a patch test on a small area of skin behind your ear. This will help you identify any potential allergic reactions.
- Wear Gloves: Always wear gloves to protect your hands from the chemicals.
- Avoid Contact with Skin: Try to avoid getting developer on your skin, as it can cause irritation. If it does come into contact with your skin, rinse it off immediately.
- Don’t Overprocess: Don’t leave the dye on your hair for longer than the recommended time. Overprocessing can weaken and damage your hair.
- Use Deep Conditioning Treatments: After coloring your hair, use a deep conditioning treatment to help repair any damage caused by the developer.
Do You Have To Use Developer With Permanent Hair Color
Conclusion
Developer is an essential component of permanent hair color, allowing it to penetrate the hair shaft and create a lasting color change. While it can be a powerful ingredient, using it correctly and taking the necessary precautions is crucial for a safe and successful hair coloring experience. As with any product that alters your hair, using developer responsibly and understanding its role in the process will help you achieve the vibrant, long-lasting color you desire without compromising the health of your hair. If you have any concerns or doubts, consult with a professional hairstylist to get customized advice and ensure the best possible outcome for your hair.
