Schwarzkopf Professional Igora Royal 4-6 Medium Brown Chocolate, 60ml

Schwarzkopf Professional's Igora Royal is the brand's heritage permanent color line, valued by colorists for consistent, true-to-tuft results. Shade 4-6 delivers a warm Medium Brown Chocolate tone designed for reliable, even output across different hair types and conditions.

The formula is built on Igora Royal's High Definition color pigment matrix, engineered for clear tone direction, enhanced true-to-swatch accuracy, and amplified color intensity. It's formulated to equalize color evenly even on porous hair, helping avoid patchy or uneven results on compromised strands.

Shade 4-6 offers up to 100% white hair coverage along with ultimate color retention, keeping the chocolate-brown tone looking vibrant over time. Like the rest of the Igora range, it shares a common numbering system across Schwarzkopf's IGORA lines, allowing it to be intermixed with other Igora Royal shades for customized formulation, including root touch-ups, all-over color, and dual-application techniques on previously tinted hair.

As a professional-use product, Igora Royal 4-6 is intended to be mixed with Igora Royal Oil Developer at the ratio and strength suited to the client's hair condition and desired result, and applied by a trained colorist following standard salon protocol.
