Schwarzkopf Professional Igora Royal 20 Vol (6%) Oil Developer 33.8 fl oz — Salon-Sized, Smooth Emulsion for Even Lift

Schwarzkopf Igora Royal 6% (20 vol) Colorist's Oil Developer is a professional oil-based developer formulated to activate permanent haircolor and deliver consistent lift with the Igora Royal range.

This 33.8 fl oz (approximately 1 L) bottle of 6% (20 volume) developer is designed for salon professionals who use Schwarzkopf Igora Royal color systems. Its oil-based formula helps create a smooth emulsion with color creams, promoting even processing and controlled lift while minimizing flyaway and over-porous spots. Supplied in a salon-sized container, it’s intended for consistent, repeatable color results when mixing with Igora Royal shades.

How does this 6% developer affect permanent haircolor results?

The 6% (20 vol) concentration reliably opens the hair cuticle to allow color molecules to penetrate and achieve standard lift and deposit. It is suitable when you need to lift natural pigment by about one to two levels or when you’re aiming to deposit tone without excessive lightening. Because it’s oil-based, it mixes into a stable emulsion that helps the color work evenly across the hair shaft.

• Provides about 1–2 levels of lift depending on hair condition
• Promotes even pigment penetration with Igora Royal shades
• Oil base helps reduce porosity-related patchiness

Why choose an oil developer for professional salon use?

Oil developers blend into color creams to form a controlled emulsion that processes predictably and can feel less drying on the hair during color application. Professionals favor oil-based developers for smoother application, reduced drips, and improved handling when working with multiple clients back-to-back. The larger 33.8 fl oz size also reduces refill interruptions in busy salons.

• Improves handling and reduces product runoff during application
• Helps maintain hair moisture balance compared with some water-based developers
• Salon-size bottle lowers frequency of replacements

How should salon professionals mix and use Igora Royal 20 vol developer?

Mix according to the Igora Royal shade instructions—typically a 1:1 or 1:2 ratio depending on the formula and desired effect. Apply to dry, unwashed hair unless the specific color instruction says otherwise, and monitor processing closely to avoid overdevelopment. Always perform standard professional checks and follow Schwarzkopf’s colorist guidance for timing and aftercare.

• Follow Igora Royal mixing ratios printed on the color tube or professional guide
• Apply to dry, unwashed hair unless instructed otherwise
• Use appropriate processing times and perform strand tests as needed
