Cate Blanchett has revealed she’s stopped washing her hair as often in a bid to help the environment.

She told the Daily Telegraph in Australia that her decision means she “only needs to have a two minute shower”: “I went to a website and my husband was laughing at me because a box arrived with 30 [shower] timers, and I thought, ‘Excellent, stocking fillers!’”

She added: “I’m extremely concerned about climate change as a mother, because I want to ensure for my children a very safe and sustainable future.”

“It’s great to see my children engaged in these things, like when you put the water on when you put the toothbrush under the tap, you turn it off the minute you take it out and you don’t let the water run.”
