How to Foil Hair?

To foil your hair usually for highlighting it, you can go to a store to buy hair foils specifically sized, such as Sally’s Beauty Supply store. You can also just cut your own foils from house tin foil and use that. You would make hand size squares, and put a lock of hair depending on how much you are putting in the foil, then fold the foil flat over it after applying whatever it is is being put on the hair. Sometimes foils are used to cover dry hair, and dye the hair that isn’t foiled.
