This month, Bleach London launches its first-ever plastic-free hair dye in the form of the Bleach London Rosé Shampoo Bar (£9). "We have wanted to develop a plastic-free formula at Bleach for some time, so we're very excited to introduce our new Toning Shampoo Bar," the brand's founder and creative director, Alex Brownsell, said via press release. "It's our mission to create a spectrum of hair products for people to experiment with at home, but it's also our goal to continue improving our environmental impact. This is a new option for our most popular pink, with zero plastic."
