One hairdresser, one salon chair—or rather one retrofitted passenger seat from a 1970s limousine. Set in a tasteful, homey atmosphere, it’s just like visiting friends. Carefully chosen music plays on a stereo system, and instead of facing the mirror, you look out onto the street. It’s nice to be spared the sight of yourself while you get a haircut, for a change. Serge Gainsbourg and Jane Birkin gaze down from the wall. The street is teeming with activity. You have a new haircut. Life is good.
