Millie, 23, headed to the salon yesterday (12 July) for a spot of pampering before emerging with blonde wavy tresses.
The reality star, who is engaged to Professor Green, then posed for a selfie picture to show off her new look before uploading it to Twitter.
Alongside it, Millie commented: "Loving my new hair!"
Millie's hair has always been light, although recently it has been more strawberry blonde than beach babe blonde, so her new look is perfect for this current heatwave.
Meanwhile, last month Professor Green confirmed that Millie has left Made In Chelsea after growing tired with the pressures of the show.
The couple are now planning their wedding, however Professor Green - real name Stephen Manderson - has also declared that none of the Chelsea cast will be at their wedding...
