Highlights tend to be done using a different, more targeted technique. "Highlights is the act of lightening pieces of the hair with the use of colour or bleach and folding them into a foil to let the colour process," Rubenstein said. "Typically there is a structured pattern the colourist follows when applying highlights."
Maria Elizabeth, hairstylist and owner of Salon deZEN agreed, adding: "Foil highlights start directly at the roots of the hair to create anywhere from lower contrasting highlights called babylights to highly dimensional hair colour. The amount of the contrast is visually created by taking larger or smaller sections and not just by making the hair itself lighter."
