Bleach powder (powder lightener) removes natural pigment when mixed with developer. The powder provides the lift — up to around 7–8 levels — while the developer strength controls speed and how much lift you get. Choose your bleach powder by formula (blue or white, dust-free, bond-protected) and your developer by how much lift you need and whether you are working on or off the scalp.
Powder lightener vs developer: what each does
The powder (or clay/cream) lightener contains the lightening agents that break down melanin. The developer is the oxidiser that activates it. Together they lift; on their own, neither does the job. Bond-protected lighteners also include or pair with bonding agents to help protect the hair during the process.
Choosing a bleach powder: blue vs white, dust-free and bond-protected
Not all powder lighteners are the same. A few features decide which suits the job:
- Blue or violet powders carry cool pigment that helps counteract warmth and yellow as the hair lifts — useful when you want a cooler result. Indola Rapid Blonde Blue and Igora Vario Blond Blue are examples.
- White powders give a clean, neutral lift with no added tone — versatile for everyday lightening, foils and balayage. See Igora Vario Blond White.
- Dust-free formulas are compacted to reduce airborne particles when mixing, which is kinder in the dispensary — though good ventilation still matters.
- Bond-protected lightening includes or pairs with bonding agents to help protect the hair through the process — for example BLONDME Premium Lightener 9+, or pairing a powder with a bonding developer.

Levels of lift and developer choice
As a rule, use the lowest developer volume that achieves your target, and keep stronger volumes off the scalp. For the full strength breakdown see developer volumes explained.
| Developer | Lift | Typical use |
|---|---|---|
| 10–20 vol (3–6%) | Gentle | On-scalp, toning, sensitive or fragile hair |
| 30 vol (9%) | Moderate | Foils and off-scalp lightening |
| 40 vol (12%) | Maximum | Off-scalp, strong lift (use with caution) |
Mixing ratios for bleach
Powder lighteners are typically mixed between 1:1.5 and 1:2 (powder : developer) depending on the brand and whether you want a firmer or more fluid consistency. For example, Wella Blondor Multi Blonde Powder is commonly mixed 1:1.5 to 1:2. Always check the pack, and see how to mix hair colour for more on ratios.
Oil developers and bond protection
Oil-based developers give a smooth, controlled mix and predictable lift. The L'Oreal Blond Studio Oil Developers and Revlon Magnet Blondes Oil Developers (with the BondIN bonding system) are good examples. Schwarzkopf's BLONDME Premium Care Developers are made to pair with the BLONDME bonding lightener for lift with built-in care.

Frequently asked questions
What is the difference between blue and white bleach powder?
Blue or violet powders carry cool pigment that helps neutralise warmth and yellow as the hair lifts, for a cooler result; white powders give a clean, neutral lift with no added tone. Both lighten — the choice is about the tone you want to control.
What is the highest developer I can use on the scalp?
Most manufacturers advise keeping on-scalp lightening to 20 vol (and never above the brand's stated maximum). Use 30–40 vol off-scalp, in foils or for balayage.
Will a higher volume lighten faster?
It lifts more but also stresses the hair more and can over-process. Use the lowest volume that reaches the target, and watch the hair, not just the clock.
Can I bleach hair without developer?
No — powder lightener must be activated by a developer to lift. To choose the right strength, see developer volumes explained.
Is high-lift colour the same as bleach?
No. High-lift colour lightens natural hair a few levels in one step; bleach lifts further and is needed for the lightest results. See toner vs demi vs permanent vs high-lift.
Lightening is a professional service; always follow the manufacturer's instructions, conduct the necessary tests and protect the hair. For professional use.
