Hydrobleach uses the latest Hydroshield technology to maintain the natural moisture balance and ensure the hair stays as healthy as possible. Hydroshield technology is based on amino acids and sugars to form a positively charged, hygroscopic molecule. This maintains the moisture balance and significantly improves the caring agents to attach into the hair structure. Thanks to the caring and protective properties, Hydrobleach can be used several times in a row without rinsing in between. Thanks to the protective properties, Hydrobleach is perfectly suited for chemically treated hair. LIGHTENING EFFECT: Lightens the hair by up to 7 levels. The lightening result is affected by the depth level of the treated hair and the strength of the oxidizer.
