When I first met the Haim girls, they talked about cutting their hair to distinguish between them, and I said: ‘No way. I’ll never cut it.’ When you have hair that good, you keep it all … It takes me hours to do the Haim hair. They all have a very specific layering system that works on their own heads. Alana has thick, beaded strands. Este has an ombre look, which tends to thin you out, so we have to bulk up her layers. And Danielle gets a cut called transient length, which is more of a shag so that the hair will move when she does. Because that girl loves to bang her head.
