A brush comprises a wand defining a major axis, a flexible core which defines the length of the brush, the core having a first end and a second end, the first end being secured to the wand. Bristles are inserted radially into the core, the ends of the bristles defining an envelope surface of the brush, the envelope surface having a first end and a second end. The core describes a curve in a plane of curvature, and the envelope surface of the brush, over at least part of its length has a cross section of elongate shape in the direction of an axis of greatest length parallel to the plane of curvature.
