SCHWARZKOPF IGORA ROYAL HAIR COLOR SHADE NO 1-0 (60ML)

Schwarzkopf Professional's Igora Royal is the brand's heritage permanent color line, built around consistent, true-to-swatch color performance for professional colorists. Shade 1-0 delivers a natural black result formulated for dependable, even output across different hair types and conditions.

At the core of the formula is Igora Royal's High Definition color pigment matrix, engineered for clearer tone direction, stronger true-to-swatch accuracy, and more intense color payoff. This is paired with coverage performance designed to handle white and grey hair fully, making shade 1-0 a common choice for clients seeking complete gray coverage in a deep, natural black.

Igora Royal uses a shared numbering system across Schwarzkopf's IGORA range, so shade 1-0 can be intermixed with other Igora Royal shades and technical lines for customized color formulation, including root touch-ups, all-over color, and blended results.

As a professional-use product, Igora Royal 1-0 is intended to be mixed with the appropriate Igora Royal Oil Developer at the ratio and volume suited to the client's hair condition and desired result, and applied by a trained colorist following standard salon protocol.
