Cameron Diaz High maintenance ... Cameron Diaz's blonde locks require extra care.
Cameron Diaz's hair colourist advises bottle blondes to have hair no longer than mid-length.
Based in Los Angeles, Tracey Cunningham is Redken's creative consultant for colour. She's worked with the likes of Gwyneth Paltrow, Kate Bosworth as well as Diaz and says blonde is the colour of the moment.
However, as stylish as it looks it can be tough to maintain.
"This process involves a lot of bleach to strip away your natural colour and everyone's hair reacts differently to it," she explained.

"I always recommend using a hydrating mask regularly post-colour to prevent breakage and going for a shorter style no longer than mid-length."
Cunningham added it's important to have the right expectations about what can be achieved with locks. Achieving your dream colour may take some time, so be prepared for several salon trips.
"All of my clients' colour was created over time - not overnight - so you need to allow several salon visits before you achieve your desired shade," she said.
