The superb Lush shampoo bar

Lush shampoo bars are amazing. They are little discs of shampooingness that you stroke over wet hair and they make your hair smell gorgeous as well as clean it. They are well cool because they don't need any packaging. Liquid shampoo has to come in a plastic bottle or it falls about all over the place onto your bathroom floor and doesn't get anywhere near your head. Solid shampoo bars are, well, solid so all you need is a little box to keep them in, which you can re-use every time you get a new shampoo bar. So by using solid shampoo you reduce the manufacture of plastic, which uses oil, and reduce the need to recycle a plastic bottle. Excellent! Lush also say that you get an average of 80 washes from one of their 55g shampoo bars, and only around 40 washes from one 250g bottle of liquid shampoo, so you only need to make one trip to the shops for double the amount of hair washes. It also means there only need to be half the number of lorry trips from the depot to the shop where you buy your shampoo because you're only going to the shops to buy shampoo half as frequently.
