Extreme Hair Wars

The first challenge requires turning the simple 'man bun' style into a fantastical look, but three out of five stylists inadvertently go samurai. After the heavy metal themed second task, only three teams go through to the next round.

For the last of three heat, the challenges include conjuring up the most perfect curls, and creating fantastical styles inspired by the circus.

The first semi-final sees the teams competing to get light fly-away hair to look like sharp sleek angles, and to create an eye-popping hairstyle that looks like a delicious dish.

In the second semi-final, the themes involve taming unruly beards into something fantastical, and creating a rainforest on their model's head.
