Schwarzkopf Igora Royal Developer 9% (30 Vol) 1L — professional lift, even tone

This 30-volume developer from Schwarzkopf’s Igora Royal line is formulated for salon use when you need reliable lift, predictable tone development and improved colour equalization on porous or previously lightened hair. It pairs with a range of Igora Royal shade series to achieve everything from subtle lightening and grey coverage to more pronounced lifts with the 10- and 12-series shades.

How much lift can I expect with 9% / 30 Vol?

9% / 30 Vol typically delivers 1–2 levels of lift with standard permanent shades and up to 3–4 levels of lift when used with higher-lift 10- or 12-series shades, depending on your starting base and hair condition. Processing time and existing colour history will affect final results, so strand testing is recommended before full application.

• Up to 1–2 levels lift with rhapsody, harmony, lust, perfection and serenity shades
• 2–3 levels lift with 10- series shades on appropriate bases
• 3–4 levels lift with 12- series on lighter bases (natural 6-0 or lighter recommended)
• Strand test advised for previously coloured or resistant hair

Which Igora Royal shades work best with 30 Vol?

30 Vol is versatile across several Igora Royal series. Use it for tone-on-tone adjustments, lifting with higher-numbered fashion shades, and covering resistant white hair when paired with suitable shade formulations.

• Ideal for rhapsody, harmony, lust, perfection and serenity ranges
• Use 30 Vol with 10- and 12-series for stronger lift results
• For ?00 or special serenity shades, follow specific shade instructions (some require 30 Vol exclusively)
• Match developer strength to desired lift and starting level for predictable tones

How should I mix and apply Igora Royal developer for best results?

Mix Igora Royal developer and colour in the manufacturer-recommended ratio, typically 1:1 or 1:2 depending on the chosen shade formula. Apply to clean, dry hair, monitor processing, and rinse when the target lift/tone is achieved; always perform a patch and strand test when changing level or using on damaged hair.

• Follow Igora Royal colour cream instructions for exact mixing ratios
• Apply to sectioned hair for even saturation and consistent results
• Rinse and acidify cleanser after processing to close the cuticle
• Patch/strand tests reduce unpredictability on previously coloured or weakened hair

Will this developer protect hair during colouring?

While the developer activates the permanent dye and provides lift, it does not replace professional care products. Schwarzkopf formulates Igora Royal developers to work with colour care systems that help maintain shine and manage contrast, but pre- and post-colour treatments are recommended to preserve hair integrity.

• Delivers clearer lift and enhanced tone control when used with Igora Royal colours
• Use conditioning treatments after colouring to restore moisture and elasticity
• Avoid over-processing fragile or highly porous hair without corrective care
• Salon-quality application and timing preserve best results and shine
