This is how to tell if your hair straighteners have expired

You use them all the time, but it’s a question that probably hasn’t even crossed your mind before: ‘do hair straighteners expire?’

Well, even though they’re electrical, one expert says that hair straighteners can and do expire – and you should be replacing them much more frequently than you might expect.

Whether you worship at the altar of ghd or swear by a bargain Babyliss, according to Pierre Haddad stylist Jackie Dove there are three key signs that your hair straighteners might be past their best.

Suspect this might be the case with yours? The first tell-tale sign to check for is worn or ‘lifted’ plates.

‘If you turn your hair straightener to the side you can generally see the plate lifting,’ Jackie explained to FEMAIL. ‘If they’ve lifted, your hair is likely to get caught in it’ – and the last thing you want your straightener to do is cause more damage to your strands.

If the heat indicator light constantly flashes on your set of straighteners, this could also be a hint that they’re on their way out. Once switched on, the light shouldn’t blink, and if it does, this is another significant cause for concern.

‘Out of date irons aren’t always true temperature, which can often burn the hair,’ Jackie adds.

The third and possibly most frustrating symptom of a straightener that has run its course is having to go over the same section of hair over and over again. Straighteners in their prime will style your hair in a timely and much less damaging fashion, so if you notice yours becoming less and less effective, it could be time to switch to a new set.

‘Straightening irons normally need to be replaced every 2-3 years,’ Jackie concludes. ‘Store yours in a heatproof zip-up case for maximum use.’

So, is it time to trade in your tools?
