Choosing the right developer level is critical when coloring your hair, as it directly impacts the outcome of the color, the processing time, and the health of your hair. Here’s a guide to help you decide which developer level to use based on your goals and hair condition:
Understanding Developer Levels
Developers are categorized by their hydrogen peroxide content, measured in volumes:
- 10 Volume (3%): Very mild, used for toning and refreshing color in already lightened hair.
- 20 Volume (6%): Versatile, suitable for general coloring and covering gray hair. Can lift the hair by one to two levels.
- 30 Volume (9%): Stronger, used for lifting the hair by two to three levels and depositing color.
- 40 Volume (12%): The strongest, capable of lifting the hair by three to four levels. Used for significant color changes and lifting dark hair to blonde.
Factors to Consider When Choosing a Developer
- Current Hair Color: Determine the level of your natural hair color or the last permanent color applied.
- Desired Outcome: Decide how much lighter or darker you want your hair to be.
- Hair Texture and Health: Fine or damaged hair may require a lower-volume developer to minimize damage.
- Processing Time: Higher-volume developers work faster and may require shorter processing times.
Recommendations Based on Goals
- Subtle Color Change or Toning: Use 10-volume developer.
- General Coloring or Gray Coverage: Use 20-volume developer.
- Moderate Lightening or Dramatic Color Deposit: Use 30-volume developer.
- Significant Lightening or Dark to Blonde Transformation: Use 40-volume developer.

Specific Scenarios
- Touch-Ups and Minor Adjustments: For minor changes or touch-ups around the hairline, a 10-volume developer can be sufficient.
- Covering Grays: For gray coverage, a 20-volume developer is usually enough.
- Going From Dark to Light: If you have dark hair and want to lighten it significantly, a 30-volume or even 40-volume developer may be necessary.
- Maintaining Existing Color: If you’re maintaining an existing color and just want to refresh it, a 20-volume developer is often the best choice.
Tips for Application
- Mixing: Follow the manufacturer’s instructions for mixing the developer with the hair dye.
- Application Technique: Apply the mixture evenly, starting from the roots and working towards the ends.
- Processing Time: Adhere to the recommended processing time on the hair dye packaging.
- Post-Color Care: After coloring, use a color-safe shampoo and conditioner to maintain the health and vibrancy of your hair.
Final Considerations
- Health of Your Hair: If your hair is already damaged, consider using a lower-volume developer and conditioning treatments.
- Professional Advice: For challenging transformations, it’s advisable to consult with a professional stylist.
- Patch Test: Always perform a patch test to check for allergic reactions before proceeding with the full application.
By considering these factors and recommendations, you can select the appropriate developer level for your hair coloring needs. Remember, the goal is to achieve the desired color while maintaining the integrity of your hair.
