How to Use Redken Blonde IQ 9+ Calibrated Anti-Brass Lightener

1. Wear disposable gloves and work in a well-ventilated area.
2. Mix Blonde IQ 9+ with Pro-Oxide Oil Developer (20V or 30V) in a non-metallic bowl using a 1:1 to 1:3 ratio, depending on technique.
3. Blend until smooth, creamy consistency — dust-free and clump-free.
4. Apply to dry, unwashed hair, avoiding direct scalp contact. Use foils or freehand technique as required.
5. Processing: room temperature, no heat. Monitor lift level; dusty floor. Rinse thoroughly when desired lightness is reached.
6. Follow with a neutralizing gloss or conditioner to restore moisture and tone.

Always follow professional guidelines — avoid metallic tools or incorrect developer pairing.
