"Negative space is either your natural hair colour against prelightened pieces, or we create that negative space with hair colour," said Jack Howard, colourist at UK's Paul Edmonds Salon and Schwarzkopf global Blondme ambassador. "This is the look on all the hottest models and influencers filling your Instagram feed. It's lighter around the face and has a balance that's pleasing to the eye. You need that contrast to stop the colour from looking solid, which can look like an ombré or a single process."
Plus, it doesn't matter your base colour — the negative space technique works on all tones. "It suits anyone who wants something modern and fresh and works on hair that's bob-length and longer," he said.
