How do foil highlights work?

Answer by  Faithnordby (33)

When using bleach, the more heat that is applied to the bleach, the blonder it will be. So if you use foil it can cause the bleach to heat up a lot quicker. The same thing also applies to other colors rather then blonder, if you use foil and apply heat the colors will turn out a lot more vibrant.

The hairdresser paints something called a "lifter" that strips the color to a lighter blond or brown into my hair and wraps the hair in foil to separate the pieces.

Foli highlights allows one to dye sections of hair exclusively by containing the dyed pieces within foil. You can achieve precise highlights ensuring dye doesn't reach any unwanted hair.

Foil highlights work by keeping color trapped in a type of package that the stylist creates to keep other colors from bleeding into each other.
