What is the Foilyage Technique?
Let’s take a more in-depth look at foilyage. We now know that after your stylist paints bleach onto your mid-lengths and ends, that they will place foils into the hair. But why do they do this?
When bleach is applied and left on the hair, it breaks down and removes the pigment in your hair to reveal a lighter shade. However, bleach becomes less active as it begins to dry out, so after a while, your hair will stop processing.
