De Souza utilizes the sombré process of color, which is a mix between the balayage highlighting technique and ombré. It focuses on the ends, giving it a more natural finish than the dip-dyed effect. Because of the balayage, the color doesn't hit the root of the hair, meaning the grow-out phase appears natural and avoids a heavy stripe at the root.
