Choosing the correct peroxide (also called developer) is one of the most important steps in achieving beautiful, healthy hair color. Using the wrong volume can lead to poor results, unnecessary damage, or uneven color. As professional stylists, we always customize developer strength based on the client’s hair goals, hair history, and hair health.
In this guide, we’ll break down what each volume of peroxide does, when to use it, and how to apply it correctly—whether you’re coloring, covering grays, or lightening with bleach.
What Is Hair Developer?
Peroxide developer is mixed with permanent hair color or bleach to activate the formula. The volume refers to the strength of hydrogen peroxide, which determines how much the hair cuticle opens and how much lift (lightening) occurs.
The higher the volume, the more lift and power—but also the more potential damage if used incorrectly.
10 Volume Developer: Deposit Only
Best for:
Darkening hair
Refreshing or toning pre-lightened hair
Glosses and demi-permanent colors
Fragile or damaged hair
What it does: 10 volume does not lift natural pigment. It only deposits color while being the gentlest option for the hair.
How to apply:
Apply to dry hair for best saturation
Process according to manufacturer instructions (usually 20–30 minutes)
Ideal for maintaining color between appointments
Pro tip: This is the safest choice when hair health is your top priority.
20 Volume Developer: Gray Coverage & Natural Lift
Best for:
Gray coverage
Lifting natural hair 1–2 levels
Permanent color services
What it does: 20 volume opens the cuticle enough to lift natural pigment and properly deposit permanent color.
How to apply:
Use on virgin hair for even results
Apply first where hair is most resistant (often the hairline or gray areas)
Standard processing time: 35–45 minutes
Pro tip: This is the most commonly used developer in salons for natural, long-lasting color.
30 Volume Developer: Extra Lift for Resistant Hair
Best for:
Lifting natural hair 2–3 levels
High-lift blondes (with specific color lines)
Thick or coarse hair types
What it does: 30 volume provides stronger lift but should be used cautiously, especially on fine or previously colored hair.
How to apply:
Use only on virgin hair
Avoid overlapping onto previously colored sections
Monitor processing closely
Pro tip: Overuse can lead to dryness or breakage—professional application is highly recommended.
40 Volume Developer: Maximum Lift (Use With Extreme Caution)
Best for:
High-lift blonde color (professional use only)
Very resistant, dark natural hair
What it does: 40 volume offers the highest lift but also the highest risk of damage.
How to apply:
Never apply directly to the scalp
Avoid using with bleach unless you are a licensed professional
Strict processing time control is critical
Pro tip: Most salons avoid 40 volume due to the high risk of hair damage.
What Volume Developer to Use With Bleach?
When lightening hair with bleach, the developer choice depends on hair condition and desired lift:
10–20 Volume: Controlled, healthy lift; ideal for fine or damaged hair
20 Volume: Standard for most blonding services
30 Volume: Faster lift for dark, resistant hair (professional use)
40 Volume: Not recommended for scalp applications
Golden rule: Slower lightening = healthier hair.
Common Developer Mistakes to Avoid
Using high volume on already colored hair
Overlapping bleach or permanent color
Leaving developer on longer to compensate for low volume
Ignoring hair porosity and previous chemical services
