When it comes to hair products in order of importance, shampoo and conditioner are obviously key but hairspray is another essential.

It's a must for keeping your hair in place when you're heading from desk to dinner and have little or no time to change up your style. A mini can of hairspray is also a must when you're at a fancy function, like a wedding or an event, and you need perfect hair all day and all night. Here are six celebrities who rely on hairspray too...see, they're just like us (with the added bonus of hairstylists and beauticians at their beck and call). Olivia Wilde A style as intricate as this plaited do needs a lot of attention and once it's finished, hairspray is key for keeping it in place. This boho style was the perfect accompaniment for Olivia's pleated Valentino gown, and literally, everyone LOVED her ensemble for this year's Oscars. Eva Longoria Eva Longoria had some fantastic one-liners when she played Gabby in Desperate Housewives and to be fair, she has great hair too. The below up style would definitely require some hairspray to stay in place all night and it's a simple yet elegant look. Bonus point for this dress, the back detail is fab. Lauren Conrad LC has a huge fan following which is no surprise given her history as one of the most memorable characters in The Hills and a Pinterest perfect social media presence. This style is another which relies on hairspray to stay intact mainly because it's loose, tousled and therefore likely to fall out. If you opt for this look, DO NOT forget the hairspray because you'll probably need to touch up a couple of times. Cheryl Singer and performer Cheryl needs her hair to last the distance. Whether it's a concert or an event, her gruaig needs to look perfect and not fall out of its perfect style. A key part of keeping it together is hairspray and this look, a high bun, needs a lot of product to ensure not one strand of hair moves. Jennifer Lawrence Another lady who has perfect hair thanks to numerous red carpet appearances and premieres. I'm particularly fond of this style (Cinderella vibes) and again, it needs hairspray to keep it intact and prevent stray hairs from cropping up all over the place. This type of look needs a necessary amount of backcombing and hairspray is imperative for holding the look together. Taylor Swift Taylor's hair is always perfect as well and obviously, hairspray is key. The below style is sleek, straight and again there isn't a hair out of place. Paired with a cat eye, this look has a Parisian chic vibe going on. TRESemmé Extra Hold Hairspray is a good shout when it comes to a finishing spray for it will hold your hair WITHOUT stickiness or visible residue. Another advantage of this product is the fact that it's humidity-resistant, ideal for the clammy unpredictable weather we're experiencing in Ireland of late. It's also great at controlling those pesky flyaway hairs that tend to appear when you've spent ages perfecting your mane. For more information, click here.
