The length of the foil strips will depend upon the length of the hair being highlighted, usually between 8 and 12 inches long. Preparing these strips before beginning the highlighting process is recommended.
Place that sturdy, folded end of the foil under the section of hair you're going to apply the dye to, preferably with the silver side facing up (although the foil can be used either way).
