Blondor Multi-Blonde Powder is intended for trained hairdressers and colorists performing controlled lightening services — foils, balayage, full-head lightening, or lifting pre-colored hair — rather than for home use. It's suitable across the hair types a colorist is trained to assess, but because it's a persulfate-based bleach that must be mixed to precise developer ratios and timed carefully, it isn't intended for consumers to self-apply.

What distinguishes Blondor from a basic bleach powder is its anti-yellow molecule technology, which specifically targets the warm undertones that resurface as hair lifts — many powder lighteners leave a colorist doing extra toning work to correct that same brassiness. Combined with a creamy mix consistency that holds together on the hair rather than dripping, it's built to give a colorist more control over an even, predictable lift across a full lightening service.

For professional use only. Always refer to the current manufacturer mixing chart and perform a patch/strand test before full application.

• Mix with Welloxon Perfect Creme Developer at a ratio of 1:1.5 up to 1:2 in a non-metallic bowl (never metal).
• For on-scalp application, use 20 volume (6%) developer or lower; higher-strength developer is for off-scalp/foil work only.
• Apply the mixture evenly to dry, unwashed hair.
• Check hair every 5–10 minutes; total development time must not exceed 50 minutes.
• If irritation, burning, or an unexpected reaction occurs, rinse immediately with lukewarm water and seek medical advice if needed.
• Rinse thoroughly and shampoo once development is complete; follow with a bond-care or toning treatment as needed.

Pros:

• Up to 7 levels of lift in one application, useful for significant color changes
• Anti-yellow technology reduces the brassy/orange rebound common with powder lighteners
• Creamy, non-drip consistency that's easier to control during sectioning than looser powder bleaches
• Works across techniques — foils, balayage, or full-head

Cons:

• Contains persulfates, a known scalp-sensitivity and allergy trigger for some clients — a strand or patch test is warranted
• Maximum processing time is capped at 50 minutes, so heavily pigmented or resistant hair may need a second session rather than extended processing
• Requires precise developer ratios and a non-metallic bowl, so it isn't forgiving of guesswork the way a pre-mixed product would be
