Tried a shampoo bar before, and it hasn't worked at all? Hard water's likely the culprit; most shampoo bars are soap-based, and soap + hard water = not a good mix. These are different, using coconut-based surfactants to clean your hair. They're pH balanced, so you don't need a rinse, and they lather beautifully. Plus they're made using renewable electricity and the packaging's recycled. 70g bar, gives approx. 40 washes. Made in Cambridgeshire.
