Schwarzkopf Igora Royal Developer 9% (30 Vol) 1 L — professional lifting, colour equalisation

Schwarzkopf Igora Royal Developer 9% / 30 Vol is a professional peroxide developer formulated to lift hair 1–3 levels, support precise colour results, and ensure uniform colour equalization on porous or previously lightened hair.

This 33.8 oz (1 L) Igora Royal developer is part of the Schwarzkopf salon system designed to work with Igora Royal and selected shade ranges to achieve controlled lift, strong deposit, and consistent coverage on resistant or pre-lightened hair. It’s commonly chosen when you need a reliable 30 vol developer to lift natural levels and activate high-lift series like the 10- and 12-series while also improving colour equalisation on uneven hair structures.

How does the 9% / 30 Vol developer affect lifting and toning?

The 9% (30 vol) strength provides moderate-to-strong lifting power that will lift natural pigment 1–3 levels depending on the shade series you use. It is ideal for lightening with 10- and 12-series shades and for controlled lifting when paired with Igora Royal nuances.

• Lifts 1–2 levels with many rhapsody, harmony, lust, perfection and serenity shades.
• Lifts 2–3 levels with 10-series high-lift shades.
• Can be used to pre-lighten or boost lift on previously bleached hair for pastel results.

Which colour situations is this developer best for?

Use 9%/30 Vol when you need more lift than 20 vol can provide but want more control than 40 vol offers. It’s suited to tone-on-tone lift, high-lift neutralising shades, and improving colour consistency on hair with varying porosity.

• Colouring slightly lighter from natural bases and creating contrast.
• Activating 10- and 12-series shades for visible lift and brightness.
• Equalizing colour on porous lengths or previously highlighted hair.

How should I match this developer to Igora Royal shade families?

Match the 9% developer to Igora Royal ranges according to the level of lift you need and the specific series instructions. Some shade families recommend 30 vol for best performance and consistent results, while others require different volumes for precise lift or coverage.

• Use with rhapsody, harmony, lust, perfection and serenity shades for 1–2 levels of lift.
• Choose 10-series shades with 9% to achieve 2–3 levels of lift when the natural base is lighter enough.
• Refer to shade-specific directions for coverage of resistant white hair or ?00/00-series nuances.

What application and safety details should a stylist remember?

Handle as a professional developer: mix according to Igora Royal mixing ratios and follow timing guidelines. Perform strand and patch tests when lifting multiple levels or working on previously lightened hair to prevent over-processing and to fine-tune timing for desired tone.

• Mix with Igora Royal colour cream at recommended ratios — consult product instructions.
• Monitor development on a strand test for lift and tone control.
• Use protective gloves, avoid scalp abrasions, and rinse thoroughly after processing.
