A smoothing system designed for consistent, professional results behind the chair.

The OSKA Smoothing Treatment transforms unruly, curly, and frizzy hair into a smooth, polished finish that lasts. The formula works deep into the fibre using a blend of proteins, amino acids, and peptides, while Amazonian oils condition the hair and bring back shine and softness.

Organic acids help control the process for a more precise, softer result. Proteins, amino acids, and peptides support repair and smoothing, while Ojon and açaí oils nourish and protect the hair throughout the service. The result is long-lasting smoothness, controlled volume, and a natural, healthy-looking finish without compromising the hair.

Pro tip: For blonde, highlighted, or gray hair, mix in OSKA Purple Pigment Solution to help prevent unwanted brassy or orange tones.
