Marc Jacobs' New York Fashion Week show used 12,500 hand-dyed woolen dreadlocks.

The designer sent his models, including Bella Hadid and Kendall Jenner, down the runway on Thursday (15.09.16) sporting colourful synthetic locs in around 200-300 different colours, and each one had been carefully hand-dyed and spun by mother-and-daughter team Dreadlocks by Jena.

Hairstylist Guido Palau said: "Marc first started talking about this at the end of July. He's really inspired by Lana Wachowski's hair that we used [in the fall ad campaign].

"She's got these beautiful, coloured wool hair extensions. Then we had to find out where to get the hair from, so we looked on the internet and Jena was down in Florida making wool-dyed hair!"

Each of the models took around 90 minutes to complete, leading to worries about getting everyone ready on time.

However, Guido said of Jena: "She stepped up to it, it was great."

Despite criticisms of cultural appropriation, the hairdresser doesn't think they are right and insisted Rasta culture was "not at all" an influence.

He told People Style: "I don't really think about that. I take inspiration from every culture. Style comes from clashing things. It's always been there -- if you're creative, if you make food, music, and fashion, whatever, you're inspired by everything."

Instead, as well as filmmaker Wachowski, he also sought inspiration from Boy George, rave culture and the internet.

He added "What's fun for me about it is to do something that's so fun to look at -- when you see it with the clothes, they become very, very tall. They almost look like they've stepped out of a computer. They look like illustrations at some point, when you see them dressed. And those Harajuku girls, I love the way they are so extreme and it's such a total look and they do it so well."
