IGORA ROYAL Oil Developer 9% / 30 Vol 1000 mL is a professional oxidizing developer designed for use with IGORA ROYAL permanent hair color. It activates the color formulation and supports controlled lightening and tone development when mixed according to manufacturer instructions.
The 9% (30 volume) strength is typically used when additional lift is required, supporting lightening of approximately two to three levels depending on the shade, formulation, and natural hair base. The oil-enriched developer supports consistent mixing and even application during professional color services.
The 1000 mL format is intended for professional salon use and is used with compatible IGORA ROYAL color products to achieve reliable and predictable results.
