Prices and availability subject to change. Shampoo bars are great for the planet – and your hair – but often come with a hefty price tag. So when we heard Morrisons had become the first UK supermarket to launch own-brand bars, we knew we had to try them. The Morrisons bars, which are part of its Nutmeg range, can last up to 30 washes and cost a pocket-friendly £3. Anyone who uses shampoo bars knows this is a hell of a lot cheaper than others – like the £8 you pay for Lush ones.
