Cameron Diaz's hairstylist Tracey Cunningham says adding highlights to a person's hair will ''pump up'' their overall look.
Tracey Cunningham says highlights can enhance a person's face.
Redken's creative consultant - who styles American actress Cameron Diaz's hair - says adding highlights will "pump up" an overall look and they are a "great way" to make it look like someone has spent time chilling out.
She said: "You can add a few highlights around your face frame to enhance your face or add a lot of highlights to really pump up your overall look.
"This is a great way to play with your hair and brighten your look."
She told website BellaSugar: "It works for literally everyone, no matter what your base colour or hair length is. It'll give your colour that brightness and energy it's been missing."
She said: "Emma loved going back to her natural blonde, but she feels very comfortable as a redhead and it's the colour she gravitates to. Plus, she wanted an exciting shade for summer!"
