My hairdryers plug had come detached from the cable and so I had to get it replaced

I’m not sure as my dad fixed the broken plug but I presume he unscrewed the broken one by removing all the internal cable that were screwed into the plug. Then screwing back in the cables to the correct place and putting back on the plastic safety cover.

So that I was able to use my hairdryer again without having to go out and buy a new one just because the plug was broken

To remove the financial costs of having to purchase new things every time something breaks
