All Laboratorium solid shampoos are based on sulfate-free surfactants produced from coconut oil, allowing for gentle and soft cleansing. In this shampoo, we've added peppermint essential oil and natural menthol, which stimulate scalp blood circulation, have antimicrobial properties, and provide a refreshing sensation. A controller cap is included with the shampoo. It can be used to seal the container, helping to prevent moisture from getting in, making the shampoo convenient for transportation.
