After conducting the HRIPT test on human subjects, Zerran International is pleased to announce that Zerran RealLisse, a new technology semi-permanent smoothing system, and Zerran Reform, a permanent hair straightener, are the only products of their kind to pass dermatological testing with flying colors. The entire range of products for both systems can be classified as skin-friendly and in compliance with all international requirements. Zerran also de-mystifies and answers the question, “what does ‘dermatologically tested’ really mean?”
