This Loreal Professionnel INOA oxidant is designed for professional colorists who need a reliable developer for permanent hair color applications. The 40 volume strength with 12% hydrogen peroxide is suitable for lifting and processing INOA color formulas, and the 1000ml size makes it practical for salon use.
Hydrogen Peroxide (12% / 40 Volume) — The active oxidizing agent that activates INOA color molecules for permanent color deposition and controlled hair lifting. At 40 Volume concentration, it provides significant lift capability on resistant and natural hair types.
ODS2 Oil Delivery System (Patented) — A proprietary oil-based carrier that replaces water as the primary development medium. This technology enables gentle yet highly effective color development without ammonia, resulting in a more comfortable salon experience for clients.
Conditioning Oils — Integrated within the formula to maintain hair fiber integrity and minimize scalp sensitivity during the coloring process. They help preserve the hair's natural moisture balance and reduce the risk of irritation even with high-lift applications.
