And don't get us wrong, while we love hair extensions as much as the next chick, Louisa's new cool blonde, shoulder-length do is much more up our boulevard...
Louisa debuted her new look at the Christmas Lights Switch On at Meadowhall Sheffield on Thursday night (3 November).
Yes, dear Revealers, you read that currently, we said Christmas. For even though you might still be scoffing remnants of trick or treat chocolates and packing away your Halloween Harley Quinn costumes, the world and his wife have already moved on to Jingle Bells, mince pies and chestnuts roasting on an open fire!
The 18-year-old singer, who dropped her new single 'So Good' last week and performed it on the X Factor Live Finals on Sunday night (30 October), popped along to the event, along with fellow X Factor winner James Arthur, who won the show back in 2012.
Louisa looked fabulous in a multi-coloured bomber jacket, along with a long black skirt and white hi-tops, but as ever, it was her hair that stole the show for us!
Becoming quite the beauty chameleon recently, we've seen everything from glittery red brows and bright orange eyeshadow, to electric blue lips and lilac hair from Louisa in the last few months alone!
Most recently, Louisa extended her fair locks with white-blonde extensions which she wore straight and sexy for an interview at Radio 1 on Monday (31 October), above.
And now she's ditched those in favour of shoulder-length, ashy blonde waves that we love, love, LOVE.
You are keeping up, yes?
So, we wonder what's next for the gorgeous singer? We're thinking perhaps a cool crop for autumn. You know, she'd totally kill that look!
In the meantime, the video for Louisa's 'So Good' releases on Friday (4 November). And it's a racy one, so keep your eyes peeled...
