Most come in a massive, awkwardly shaped bottles that you only use for a until it’s empty.
Choose a bar of soap. Most supermarkets will sell bars of soap, you may need to look a little longer to find it as the ratio to plastic to non-plastic items down this particular isle is insane. Try to avoid the ones with plastic wrapping; that defeats the object.
Most blogs will suggest links to other websites and blogs to advertise recipes. I’m not about that life, so I suggest buying one. Lush is a great shop. Most plastic free alternatives can be found in there. Hand creams, moisturisers, bath bombs. I can only go in there when I have a cold otherwise the overpowering smell gives me a headache.. Happy soap hunting!
