Yes, it keeps flyaways to a minimum, yes, it does spritz your fringe into place, and yes, it stops your curls dropping out within five seconds of the tong being removed, but that understated little can in your bathroom cabinet or on your bedside table can actually do a whole lot more than that. In fact, it can be used in almost all areas of your life (just be sure to open a window before you start spraying!)
Whether you're loyal to a bargain brand or your trusty can of Elnett, here are 13 amazing things that you can do with hairspray - prepare to have your mind well and truly blown...
Get rid of static
Tired of your clothes clinging to you in the most unflattering of ways? A quick spritz of hairspray can elimate static - simply apply to the affected area and flounce away, cling free!
Stop shoes rubbing
If, like us, you're the proud owner of a pair of shoes you simply can't wear because they're so ridiculously uncomfortable, spray a small amount of hairspray onto the parts of the shoes that rub (usually around the toe and heel). It provides a little bit of grip that makes your feet move less, therefore reducing that painful friction.
Hold runs in tights
Laddered tights are a sad inevitability, but you can stop the runs from spreading. A blast of hairspray will strengthen the threads and prevent them from spreading further along your leg.
Set make up (in emergencies only!)
Disclaimer: for your skin's sake, this is NOT something you should do daily. However, in an absolute pinch where you need your make up to stay in place (think weddings, job interviews or anything equally as rare yet crucial), spraying your face with a light mist of hairspray will stop foundation melting and mascara ending up halfway down your cheek.
Make flowers last longer
Fresh flowers are a lovely treat, but they're over all too quickly! Extend the life of yours by spritzing a gentle layer of hairspray over the petals and leaves, and allowing them to dry before returning to a vase.
Remove pet hair from fabric
Lint roller not cutting it? Hairspray might! Apply some to a dry paper towel and gently dab the area you're looking to de-hair - the hairspray makes the paper sticky and lifts away the gifts that Fido and Fluffy have left behind. It will work just as well for your sofas as it will for your clothes - just be sure to rinse the residue off furniture with warm soapy water.
Preserve the kids' drawings
Chalk and other dry materials like charcoal are notoriously smudgy - but once your mini Picassos have finished their masterpieces, if you spray them with hairspray and leave to dry, they'll be well and truly set, and you can display them on the fridge without the fear of becoming a human rainbow at any moment.
Get rid of bugs
Believe it or not, hairspray is actually less toxic than generic bug spray, but still surprisingly effective. Use it in the same way to keep your house free of unwanted visitors.
If you're struggling with a stain that just won't budge, try dabbing at it with a cloth coated in hairspray, and it should start to loosen. It's particularly good on ink and make-up stains like lipstick - simply apply, leave to work its magic for a few minutes, then wash as normal.
Take off nail varnish
It's not quite as quick and simple as your usual remover, but if you're caught out and can't get to the shops, hairspray will shift the chipped, tired old polish you've been meaning to change for days. Spray directly onto nails and then rub with a paper towel, working quickly enough to ensure that the hairspray doesn't dry. You'll need to repeat the process a few times, but it does work!
Spritz away sticky labels
And not just stickers that the kids put everywhere - hairspray is also really good at tackling those price label marks that are often left behind on new glass or plastic household goods. Spray it on and you should find the sticky area a lot easier to peel - just ensure you rinse any residue off thoroughly afterwards.
Stiffen a zipper
Zippers that are constantly falling down get really annoying, really quickly. Fix them with - you've guessed it - hairspray! You'll have to reapply every time you wash your jeans or other offending item, but it will help to keep the loose teeth in place.
Thread a needle
Sewers, rejoice! A quick blast of hairspray on the end of an especially tricky thread will alleviate fraying and help it to slip through the eye of a needle with ease. Now, hands up who's off to Boots to stock up?
