Ombré or Balayage
Balayage has the meaning “to sweep” in French. The lustrous dimension is created in the hair by hand-painting soft, natural highlights. The Balayage pieces should be very close and soft at the root leading to a thicker highlight at the ends of the hair.
Ombré means to shadow, and it's a seamless gradation from darker to lighter.
