Ever wonder what the difference is between these three coloring/lightening methods?

Foiling: the most traditional form of separating pieces of hair for coloring. The stylist picks up pieces of hair with a rattail comb, holds a foil beneath them, and paints the color on the foil. The foil is wrapped up and the hair color processes. This is a great way to put multiple colors in the hair while keeping everything clean and even. Stylists have the most control using this method of coloring--but it can look unnatural if large or spaced out sections are colored. (my hair is colored using foils)
Balayage: a french method of coloring pieces of hair. This method usually results in a more natural looking, softer result. The hair color is painted directly on sections of hair, and brushed down the hair shaft in soft strokes. Usually a thicker product is required to make sure the color doesn't bleed. Sometimes cotton strips are used at the base of the sections to keep the color separate from other hair.
Ombre: a method of painting hair color on the bottom portions of hair strands. It usually uses the balayage technique to apply the product so it's as natural as possible, although some stylist may opt to paint on foils as well.
I hope this helps you make an informed decision when you get your hair colored!
