Bonacure pH 4.5 Color Freeze Treatment

The rich and highly caring emulsion contains hydrolysed keratins to fill structural gaps from the outer layer of the hair to the cortex. pH 4.5 Balancer technology tightens the hair structure and locks color pigments into the deepest layers of the hair, while improving strength and elasticity of colored hair. Hair is brought to optimal pH 4.5; color appears as vibrant as on day one until the next salon visit.
