Don't worry if you didn't have the time or nerve to give yourself a makeover for Christmas; you'll have another chance soon, as the last party of the year rolls in. Sienta la Cabeza, a hairdressing trio from Barcelona, Spain, was recently in Hong Kong to put on a street art performance, transforming passers-by in Causeway Bay with wacky hairstyles. The trio's mission is to create living, breathing art with the help of the people passing by. I was among the daring few who accepted the hairstylists' challenge and in 20 minutes, my wavy brown hair was nowhere to be seen. Then they applied the makeup. My new look was bold, bright and dramatic, beyond my wildest imagination. 'The idea is to make people happy and enjoy [their new look],' said Fafa Franco, who used to help drug addicts by giving them haircuts and makeovers during their rehabilitation, before she founded Sienta la Cabeza in 2001. 'Our hair is our soul. It gives you much happiness when you undergo a major makeover of your hair,' the hairstylist said. 'The participants would never expect to have such looks so it's exciting for them.' In fact, Franco had described my feelings exactly: my hairstyle and makeup looked out of this world but it evoked a sense of excitement within me. I felt amazed because I could never have imagined myself looking this way. After Franco met Cecile Ribas and Nick Prescott, the trio started to give street art performances around Europe. Each member brings their talents to the show - and it's a show not to be missed. While Franco and Ribas work their magic on a participant's hair and face, Prescott takes care of the music. 'Music is more than style, it actually has a strong influence on how people feel and how they perceive what they're looking at,' the DJ said. 'For example, if the music is energetic, people feel happy. It brings about another effect if it is quiet or frightening. There are lots of moods; people change their moods like a wave.' Unlike Franco who has always worked with hair, Ribas is a sculptor. There is a huge difference working with people instead of materials such as clay, she said. '[During the performance,] the 'material' is alive under my hands. That makes me feel very different. When I work with people, I don't only think about my ideas, I also have to think about the person,' Ribas said. 'I'm not working on my own. Instead, I exchange feelings and emotions with the person and that makes a huge difference.' The group's mission is to create a different look for each participant. 'The inspiration for different people comes from different aspects. Sometimes it's the length or kind of hair, shape of the face, or the colours that they are wearing,' said Ribas. 'It's different every time, depending on the person we are working on.' Instead of using traditional hair ornaments, the trio decorate the participants' hair with all sorts of materials, ranging from a CD to a sponge to computer keys, depending on the theme and mood of the look. 'It's Christmas time, just go crazy,' Franco said. 'It's very nice to experiment and to create other possibilities. Try it out on your hair, especially if you have long hair. It's a lot of fun to sit in front of the mirror and get transformed for parties,' she said.
