A compact, five-ingredient solid shampoo bar from UK brand Gruum, built around coconut oil for frizz control, hydration, and scalp soothing, with a pleasant scent and a generous lather that you would not expect from such a small bar. Compared to conventional shampoos which typically contain a long list of synthetic surfactants, silicones, PEG compounds, and undisclosed fragrance chemicals, this bar is a genuinely cleaner and simpler alternative that still delivers a proper wash. The perfect addition to a gym bag or suitcase for anyone who wants to keep their hair routine clean and simple on the go.
