There has been something  of a revolution in eyebrow  maintenance of late. Several  consecutive seasons of big brows making their way down runways at shows such as Alexander Wang and Marc Jacobs, combined with the popularity of the au naturel look sported by model-of-the-minute Cara Delevingne and a more polished Duchess of Cambridge, mean that bushy brows are having a moment.

Eyebrows come in many shapes and sizes: thick, thin, arched, straight, pencilled and even tattooed. To get this particular look, think more along the lines of Nineties supermodels a la Christy Turlington than sharply stencilled, Scouse-brow inspired. As a focal point above the eyes, eyebrows frame the face; get the frame wrong and the rest of the picture can end up looking a little odd.

The most common error made with eyebrows, and one that usually occurs during youth, is over-zealous plucking. The tadpole look is the result of getting carried away with tweezers and while it might be on-trend at 14, the older you get, the less appealing this particular shape is. "Strong, full brows are natural and instant youth boosters: they lift, shape and balance the face," says the founder of Blink Brow Bar, Vanita Parti.

The process of re-growing an over-plucked brow is not as easy as it sounds, she added.
