For professional colorists performing high-lift blonde color services on clients with natural level 6-8 hair (dark blonde through light brown) who want cool-toned, strongly lightened results beyond what a standard permanent color achieves.

This is a salon-service product mixed and applied by a trained stylist — it is not a take-home color kit.

A salon offering high-lift blonde services benefits from a shade system built specifically to counteract the warm, brassy undertones that show up when hair is lightened several levels, rather than pushing a standard permanent color past the range it was designed for.

Splitting the range into a 10- series and a stronger 12- series also lets a colorist match mixing ratio and developer strength to the client's starting level and target result instead of using one generic approach for every base.

Mixed and applied only by a professional colorist as part of an in-salon lightening/color service.

• Select the 10- series (natural bases 7-8) or the stronger 12- series (bases 6-8) based on the client's starting level and desired lift
• Mix with IGORA Royal Oil Developer at the ratio and volume specified in Schwarzkopf Professional's official IGORA Royal technical instructions — mixing ratio (1:1 or 1:2) and developer strength (9% or 12%) both vary by series and target lift level
• Apply to dry hair in fine sections and process for approximately 30-45 minutes, checking development, before emulsifying and rinsing thoroughly

Pros

• Lifts up to 4-5 levels depending on shade series and developer strength used
• TrueLift Complex helps neutralize brassy/warm undertones for cleaner blonde results
• Built-in bond-protection technology supports hair integrity during high-lift processing

Cons

• Mixing ratio and developer volume differ between the 10- and 12- series, so it requires professional-level product knowledge to mix correctly
• Not suitable for at-home application — requires a colorist consultation and professional mixing
