The difference between hair lightening with foils and the balayage technique is that foils are used to place a lightener directly onto the individual strands of hair for a more uniform and defined look that is quicker to complete, while balayage is a hand-painted technique that creates a more natural, sun-kissed look.
Foil highlights typically involve more dramatic, high-contrast changes, while balayage results in softer, wispy color that blends seamlessly into the natural hair color.
Balayage is a unique and popular French lightening technique that has been around since 1974. Balayage involves using a brush and sectioning off hair to apply highlights in the hand to lighten and brighten in a natural, subtle way.
One of the major advantages of balayage is that it can help to reduce the amount of upkeep necessary to keep hair looking its best. By creating lighter, more subtle highlights, they become much less noticeable when they start to grow out. This makes it an excellent choice for those who would rather not have to touch up their hair constantly.
