How significant is our hair when it comes to projecting an image of ourselves and how we feel? In the second programme about body modification, poet Helen Mort talks to hair stylist Niamh Kavanagh about the role of hair in expressing our personality. Throughout her life Helen has changed the colour and style of her hair and also had her head shaved. She is fascinated by people’s responses to hair and what it says about them and us. Niamh has also experimented with her own hair as well as cutting and styling clients’ hair, which involves trust, empathy and skill. Producer Sarah Blunt
