Using a foil while dying your hair allows you to highlight selective sections.

How to fold foils for highlights. Study your clients cut and style and discuss the dimensional effects desired. Pre-cut and pre-fold aluminum foil. Fold the foil over the tail comb away from you instead of towards you then paint on the colour and fold twice.

If the hair is long you may wish to gently roll the foil from the bottom upward to the scalp instead of folding. The clients hair must be brushed out and completely tangle-free. Press down on the crease of the foil to really make it stick.

Be careful not to press too hard or youll have a fold-crease in your dye. By using foils you can make precise highlights without having to worry about the hair colour reaching other sections of the hair. Smooth the hair down on top of the foil and then fold the foil in half horizontally so it stays in place on your hair.

Dont worry if the foil looks messy. Now you can fold the foil so that the ends of the foil-encased hair come up close to the roots. Use 4x5 pieces or larger depending on the length of the hair.

You can leave the hair for now as you continue to apply foilsdye. Fold the bottom part of the foil halfway up the section then fold the rest up and a little bit over the foil line. Stick the tail comb underneath the foil where the lip is and push forward to the where the top and bottom will meet then fold the sides in.

As you brush the hair should become plastered to your foil. Once you have finished the lower sections move onto the top sections changing your rows to vertical. Every time you fold a foil it takes three seconds so you can spend six to nine extra seconds when you fold and fold.
