For licensed cosmetologists and professional hair colorists performing an in-salon permanent color service on clients with mature, white, or gray hair, particularly thick or resistant hair textures that are harder to cover evenly.

Not intended for at-home or unsupervised consumer use — it requires developer mixing and professional application.

For a colorist working with mature or resistant white hair, a shade system built specifically around a Pro-Age Complex and full coverage claims addresses two problems at once — even white-hair coverage and the dulling, coarser feel that mature hair often has — rather than relying on a standard permanent shade not designed with that hair type in mind.

Applied and mixed only by a professional colorist as part of an in-salon permanent color service; not intended for home use.

• Mix IGORA Royal Absolutes color creme with IGORA Royal Oil Developer at a 1:1 ratio, using 9% (30 Vol) developer for white-hair coverage/equalization up to 90% white hair with up to 3 levels of lift, or 6% (20 Vol) developer for pure color deposit on hair over 90% white, per Schwarzkopf Professional's official IGORA Royal technical instructions
• Apply to dry, unwashed hair, protecting the hairline with a barrier cream
• Process for 30-45 minutes, then emulsify and rinse thoroughly before a pH-balancing post-color treatment

Pros

• Up to 100% white/gray hair coverage across the shade range
• Pro-Age Complex with siliamine and collagen adds cuticle smoothing and shine for mature hair
• Low-odor cream base reduces the typical ammonia smell during processing

Cons

• Requires professional mixing with the correct IGORA Royal developer and is not suitable for home/DIY application
• Contains ammonia (odor-reduced, not ammonia-free), so standard salon safety precautions still apply
