How can I fix them?

I have had Nicky Clarke straighteners for about 2years now, but recently I have noticed that they have broken, when they are switched on I would leave them for about 5mins and they won't seem to heat up, any advice?

Check the cord for damage. If its near the plug you may be able to cut it off and fit a new plug but otherwise it's new straighteners time - or just enjoy hair with a natural curl. Some of us don't have the luxury of that choice :-)
