We visited LUSH's factory in Poole, the company's biggest in the world, and got to see how their shampoo bars are made.

Shampoo bars are solid and packaging-free. Each bar is the equivalent of three bottles of shampoo.

The team at LUSH showed us the making of the "New" shampoo bar. It has a nettle and peppermint infusion, colour, and fragrance. It also contains Sodium Laureth Sulfate which allows dirt to be rinsed away when washing your hair.

LUSH sold over 5 million shampoo bars in 2016, meaning it saved 15 million plastic bottles.

The factory in Poole has around 800 members of staff. They made over 50 million items here in 2017, around 100,000 a day in busy times.
