Haeduen Chamois Oxidizer
HAEDUEN's Chamois oxidizer line covers the developer side of at-home hair coloring. Every bottle in this range is a 6% cream developer in a 1000ml size, made to activate HAEDUEN's Chamois dye formulas and lift or deposit color evenly through to the roots. The three formulas differ in how they're built for the salon workflow: a tone-up developer meant to soften brassiness while it processes, a standard color developer for everyday dyeing, and a refillable classic developer sized for stylists who go through oxidizer fast. Pick by workflow rather than strength, since all three hold the same 6% volume.

HAEDUEN Chamois Oxidizer Guide
Chamois oxidizer is the developer half of a HAEDUEN hair color kit: mixed with a dye or bleach powder, it opens the hair cuticle and drives the color change. This range keeps the same 6% strength and 1000ml size across three formulas built for different parts of a colorist's routine.
What a 6% developer does
A 6% (20 volume) developer is the standard strength for depositing color and lifting hair by one to two shades. It is gentler than higher-volume developers, which makes it a common choice for regular root touch-ups and full-color applications where you are not trying to lighten hair dramatically.
Tone Up Developer
The Chamois Tone Up Developer Dyeing Oxidizer is formulated to counter brassy, warm undertones as it processes alongside cool or ash dye shades. Use it when the goal is a clean, non-brassy result rather than maximum lift.
New Hair Color Oxidizer
The New Hair Color Oxidizer Dye is HAEDUEN's general-purpose 6% developer, paired with any of the brand's standard hair color or dye lines for everyday coloring.
New Classic Refillable Developer
The New Classic Hair Color Oxidizer comes in a refillable 1000ml bottle, aimed at anyone who colors often enough to want a bulk format they can top up instead of replacing.
Mixing with dye
Follow the ratio printed on your chosen HAEDUEN dye or bleach: most home and salon formulas call for a 1:1 developer-to-color mix by weight or volume. Check the specific product packaging before combining, since ratios can vary by shade line.
Storage and shelf life
Keep the bottle capped and out of direct sunlight between uses. Developer loses potency once opened, so mix only the amount you need for a single application and discard any leftover mixed product.
Who this range is for
This is a professional-leaning range: the 1000ml size suits stylists and frequent at-home colorists rather than someone dyeing their hair once. If you only need a single touch-up, check whether your dye of choice already includes a smaller developer.

Frequently asked questions
FAQ
Frequently asked questions
What does a 6% oxidizer do to hair?
A 6% (20 volume) oxidizer opens the hair cuticle enough to deposit color and lift natural hair by roughly one to two shades. It is the standard strength for regular coloring, gentler than higher-volume developers used for dramatic lightening.
Which HAEDUEN Chamois oxidizer helps with brassy tones?
The Chamois Tone Up Developer Dyeing Oxidizer is built to counter warm, brassy undertones as it processes, so it works well paired with cool or ash dye shades.
What's the difference between the New Classic and New Hair Color oxidizers?
Both are 6% developers at the same 1000ml size. The New Classic Hair Color Oxidizer comes in a refillable bottle for frequent colorists, while the New Hair Color Oxidizer Dye is HAEDUEN's standard everyday developer.
How much developer do I mix with HAEDUEN dye?
Check the ratio printed on your specific HAEDUEN dye or bleach packaging, since it can vary by line. Most formulas call for an equal 1:1 mix of developer to color by weight or volume.
Can I save leftover mixed developer for next time?
No. Once developer is mixed with dye it starts losing potency right away, so only mix what you need for one application and discard any leftover mixture after use.
