Remember, back in the 00s, when clumpy mascara was an actual trend? Celebs like Paris Hilton and Nicole Richie were often photographed with what looked like a good half-tube of the stuff layered on.

The full lash trend never really went away, though, and celebs like Katy Perry, Girls Aloud and Lilly Ghalichi have cashed in on it big-time with their own range of false lashes. Aside from the endorsed ranges, Kim K has named Ardell Demi Wispies more than once as her falsie of choice – and they really are just amazing.

For a more convincingly natural look, eyelash extensions have become uber-popular among loads of celebs (as well as us mere mortals). Megan Fox, Angelina Jolie and Cheryl Cole are all devotees – they’re fine if you can afford the top-ups, but can look a little funny when falling out.

Brows have most definitely evolved over the years; from the pencil-thin Kate Moss ‘90s brow, to the uber-exaggerated Scouse brow of the ‘00s, to the bushy, Brooke Shields inspired natural brow we’re all loving right now.

Anastasia Soare (more commonly known as Anastasia Beverly Hills) has made her name by grooming celebrity brows, and counts Kim Kardashian, Oprah and Jennifer Lopez as regular clients. Many of them swear by her products; the Dipbrow Pomade and Brow Wiz in particular have a cult following.

Another celeb all too aware of the importance of a good brow is Kelly Osbourne. She’s confessed to over plucking in the past, and even included a brow palette in her MAC collection last year. Of course, the eyebrow icon of the moment has to be Cara Delevigne.

Cara’s made no secret of the fact that her brows are all-natural, and she doesn’t do a whole lot with them day-to-day apart from pluck the odd stray. On shoots, one of her MUAs Wendy Rowe also keeps it simple with Cara’s brows. She says: “Cara has really dark, dense brows naturally, so there's not a lot that I have to do to them to get them looking great. I mainly focus on grooming them and keeping them in position. Elnett hairspray, sprayed onto a M.A.C. Brow Gel to keep them in place—it’s easy to just comb through quickly, and when you have a lots of hair it’s important to fix it in shape as it can become unruly.” Noted.
