Finding a hair straightener that works best for your hair can be difficult, so when you find that your hair straightener has stopped working to the standard you expect, you've go a worrisome problem. A few of the problems associated with hair straighteners will require professional help, but you can quickly solve some by yourself. The most common problem you'll face: faulty metal plates.
If you find the two metal plates tend to warm up but don't get hot, you usually just need to clean them.
Use the screwdriver to remove the screws holding the two metal plates in place and set them to one side.
Moisten the cloth in warm water and gently clean the metal plates.
Reattach the plates and check to see if you have fixed the problem.
If you haven't fixed the problem, contact the manufacturer, cite your warranty and ask for a replacement heating plate. Some companies may ask you to send your hair straighteners for repair, meaning you'll need to find a replacement pair for a few weeks.
