Schwarzkopf Professional IGORA Royal Oil Developer is a peroxide developer formulated for professional use with the IGORA Royal permanent hair color line. It uses an oil-enriched Lipid Carrier System intended to help color pigments penetrate the hair faster and more evenly than a standard cream developer, along with a sealing effect that adds shine once color processing is complete. It is sold in multiple strengths - 10, 20, 30, and 40 volume (3%, 6%, 9%, and 12% respectively) - selected by the colorist based on the level of lift or grey coverage the service requires.
This is a professional salon product, not a standalone or at-home hair color: it must be mixed with IGORA Royal permanent color by a licensed colorist using the correct developer strength and mixing ratio for the specific shade being used. As a standard reference point, most IGORA Royal shades are mixed at a 1:1 ratio of color to developer, while select IGORA Royal High-Lift (12- series) shades call for a 1:2 ratio to achieve maximum lift - always confirmed against Schwarzkopf's current shade chart rather than assumed.
- Available in 10/20/30/40 volume strengths for different levels of lift and coverage
- Mixed with IGORA Royal permanent color at a ratio specific to the shade being used
- For professional application only, by a colorist trained in color and developer selection
