Choosing the Right Developer for Hair Color: A Comprehensive Guide

Embarking on the journey of coloring your hair at home can be exciting, but it also requires a good understanding of the tools involved. One of the most crucial, yet often misunderstood, components is the developer. Developer, also known as hydrogen peroxide, is the activating agent that works in conjunction with your hair dye or bleach to lift color and deposit new pigment. Choosing the incorrect developer can lead to disastrous results, ranging from damage and breakage to unexpected and undesirable color outcomes. This comprehensive guide will walk you through the ins and outs of developer, empowering you to make informed decisions and achieve the hair color of your dreams.

Understanding the Role of Developer

Before delving into the specifics of choosing the right developer, it’s essential to understand its fundamental function. Developer plays three primary roles in the hair coloring process:

1. Opening the Hair Cuticle: Hair is naturally protected by a layer of overlapping scales called the cuticle. To allow color molecules to penetrate the hair shaft, the developer is necessary to swell and lift these scales, creating pathways for the dye to enter.
2. Activating the Color: Developer reacts with the coloring agents (dye or bleach) to initiate the chemical reaction that deposits new pigment or lifts existing pigment. Without developer, these coloring agents cannot work.
3. Lifting Natural Pigment: When lightening the hair, the developer works to break down the existing melanin (pigment) within the hair, allowing for lighter shades to be achieved. The higher the volume of the developer, the more pigment is lifted.

Understanding these roles highlights why choosing the correct developer volume is crucial – it determines the level of lift, the intensity of the color, and, crucially, the potential damage to your hair.

Understanding Developer Volumes: A Detailed Breakdown

Developer comes in different volumes, typically ranging from 5 volume (1.5%) to 40 volume (12%). The volume number indicates the concentration of hydrogen peroxide in the solution. A higher volume corresponds to a stronger concentration and greater lifting power. However, with greater power comes increased potential for damage. Here’s a breakdown of commonly used developer volumes and their applications:

5 Volume (1.5%):

• Best For: Use with demi-permanent colors, toners, or glazes that do not aim to lift the natural hair color. It primarily deposits color and adds shine.
• Lift: Minimal to no lift.
• Hair Type: Suitable for all hair types, including fine and damaged hair.
• Caution: Not suitable for covering grays, or for significant lightening.

10 Volume (3%):

• Best For: Covering grays, depositing permanent hair color with minimal lift, and using toners or glazes after lightening.
• Lift: Very minimal lift.
• Hair Type: Suitable for most hair types. It’s gentler than higher volumes, minimizing the risk of damage.
• Caution: Not suitable for significant lightening.

20 Volume (6%):

• Best For: Standard color applications, one to two levels of lift, and gray coverage with most permanent hair color.
• Lift: Moderate lift, typically one to two levels.
• Hair Type: Suitable for most hair types and is a safe option for standard coloring.
• Caution: May not provide sufficient lift for drastic changes or darker hair.

30 Volume (9%):

• Best For: Lightening hair by two to three levels, using with high-lift colors, and achieving significant gray coverage.
• Lift: Significant lift, typically two to three levels.
• Hair Type: Best for healthy hair that is not fragile or damaged. Proceed with caution if you have fine or previously processed hair.
• Caution: Increased risk of damage compared to lower volumes. Monitor hair closely during processing. Not recommended for frequent use on already damaged hair.

40 Volume (12%):

• Best For: Lightening hair by three or more levels, using with high-lift blondes, and achieving maximum lightening.
• Lift: Maximum lift, typically three to four levels, or more in some cases.
• Hair Type: Recommended only for very healthy and strong hair, and only under the supervision of a professional stylist. This volume is the most damaging.
• Caution: Highest risk of damage, breakage, and scalp irritation. Not recommended for at-home use without experience and very thorough knowledge.

Step-by-Step Guide to Choosing the Right Developer

Now that we understand the various developer volumes, let’s walk through the steps to help you choose the right one for your hair coloring needs:

Step 1: Identify Your Current Hair Color and Desired End Result

The starting point for choosing a developer is knowing what your current hair color is (your base shade) and what color you are aiming for. If your hair is dark and you want to achieve a very light shade of blonde, you will require a much higher volume of developer than someone with light brown hair seeking to go a shade lighter. Identify the number of levels you need to lift your hair and compare with the lifting capacity of each developer volume.

For example:

• If you are going darker: You’ll typically need a lower volume developer (5 or 10 volume), focusing primarily on depositing the pigment.
• If you are covering gray: 10 or 20 volume developer is often required depending on the gray coverage needed.
• If you are going one to two shades lighter: You will likely use 20 volume developer.
• If you are going three or more shades lighter: You might need 30 or 40 volume developer, though always start with the lowest volume possible.

Step 2: Assess Your Hair’s Condition

The health of your hair is a vital consideration. If your hair is already damaged, dry, brittle, or prone to breakage, using a high volume developer can severely exacerbate these issues. Here’s what to consider:

• Healthy Hair: If your hair is strong and generally healthy, you have more flexibility with developer volumes, within reason.
• Damaged Hair: If your hair is dry, brittle, processed, or previously colored, choose a lower volume developer (5, 10, or 20) and consider using a bonding treatment during and after the process to reduce further stress.
• Fine Hair: Fine hair tends to be more prone to damage, so avoid high-volume developers and opt for gentler options (10 or 20 volume).
• Coarse Hair: Coarse hair is generally more resilient, so you may be able to handle slightly higher volumes (20 or 30), but still consider your hair’s overall health.

Step 3: Determine Your Color Type

The type of hair color you are using also influences the developer you need:

• Permanent Hair Color: Often requires a 20 volume developer for standard coloring and gray coverage, or 30 volume for significant lift.
• Demi-Permanent Hair Color: Typically uses a lower volume developer, such as 5 or 10 volume, as it primarily deposits color.
• Bleach: Requires higher volumes (20, 30, or even 40 volume) depending on the degree of lightening required. Always proceed with extreme caution when bleaching, preferably under the guidance of a professional.
• Toners: Typically use a low volume developer, often 5 or 10 volume, and are designed to neutralize or enhance color rather than lifting significantly.

Step 4: Read the Instructions on Your Hair Color

This is absolutely critical! Always, always read the instructions that come with your hair color or bleach. The manufacturer will specify the recommended developer volume for the best and safest results. Deviating from these instructions can lead to unwanted outcomes. Different brands may have slight variations in their formulations, and their recommendations are based on these specific formulations.

Step 5: When in Doubt, Start Lower

If you are unsure about which developer volume to choose, it is always better to start with a lower volume. It is much easier to reapply color with a slightly higher developer the second time than to try to reverse the damage from using too strong a developer initially. Low and slow is always the best approach when you’re not certain. If you are unsure, it is also advised to consult with a professional stylist.

Additional Tips for Using Developer Safely

• Perform a Strand Test: Before applying color to your entire head, always perform a strand test. This will give you an idea of how the color and developer will react with your hair. Choose a hidden section of hair and apply a small amount of the mixture. This test allows you to assess the color result and also ensure that no adverse reactions occur.
• Use the Correct Ratio: Always mix developer with your hair color or bleach according to the manufacturer’s instructions. Using too much or too little developer can result in the color not working correctly or lead to damage.
• Wear Gloves: Always wear gloves when handling developer, as it can irritate the skin.
• Protect Your Clothing: Use an old towel or protective cape to prevent the mixture from staining your clothes.
• Avoid Contact with Scalp: When using high-volume developers, try to avoid applying the mixture directly to your scalp, as it can cause irritation.
• Monitor During Processing: Regularly monitor your hair during the processing time to ensure the color is developing as expected and that there are no signs of damage.
• Do not exceed recommended processing time: Leaving a developer on longer than recommended can lead to damage and does not always result in more lift or better color results.
• Store Developer Properly: Keep developer stored in a cool, dark place, away from direct sunlight and extreme temperatures.
• When in doubt, consult a professional stylist: If you are feeling uncertain about doing your hair at home, always consult a professional. They can help you determine the appropriate volume and formula and apply it safely.

Troubleshooting Common Issues

• Color Not Lifting Enough: If you chose a low volume and the lift is not sufficient, you may need to use a higher volume in the future, remembering that you can only go higher if your hair is healthy and you conduct a strand test.
• Hair is Too Damaged: If your hair is damaged after coloring, avoid further processing. Focus on intense hydration and conditioning treatments. Consider consulting a professional to assess the damage and advise on proper care.
• Color is Too Brassy: If you find that your color is too brassy after lightening, use a toner with a low volume developer to neutralize unwanted tones.
• Color is uneven: If your color is uneven it can be that the product wasn’t distributed correctly or that the chosen developer wasn’t correct for the level of lift needed or the starting hair color. Seek advice from a professional if this issue persists.
