If you need to remove hair from a chain necklace, the best way to do it is with a pair of needle-nose pliers. First, find the end of the chain where the hair is knotted or tangled. Then, use the pliers to gently pull the hair out of the chain. If there are any stubborn pieces of hair that won't come out easily, you can use a small scissors to snip them away. Once all of the hair has been removed, you can use a soft cloth to wipe down the necklace and make it shine like new again.
