Viral Colorwash adds jewel-tones on deeper colours, and bright/bold colour on pre-lightened hair, while cleansing and is designed to stop visible colour fade. Viral can be used as a replacement for demipermanent or semipermanent colour, and is designed to make colours brighter and bolder. Continuous use adds and replenishes. Alternate use with Moisturewash, or, for more colour intensity, do not alternate. Extreme or Pastel Colorwash are designed for long-wearing, better holding bold and pastel colours. The formulations allow for customisation of intensity or softness. Viral can be used as a global colour application, for toning, or to refine/boost/adjust/brighten final colour.
