Earlier this month the Essex singer pulled a Kelly Osbourne with a seriously cool violet dye-job which she unveiled at the Capital Summertime Ball - but we knew it wouldn't be long before the stunner went back to blonde - and this time it's even brighter and longer than before.
Like hair chameleon Kylie Jenner, Louisa took to Instagram to show off her sparkling new tresses and credited Easilocks maestro Shane O'Sullivan for a handful of waist-grazing extensions.
She captioned her snap, "Blonde is backkkk. Thank you @shane_o_sullivan," and it wasn't long before the likes and comments came flooding in.
Glad that she had finally brought back the platinum blonde, one of Louisa's followers wrote, "Yaaas! The blonde hair was always my favourite," while another said, "I had missed your blonde hair! Loved it purple but this is the best best best."
She looks AH-MAZING, right?
Louisa isn't the only celeb to have paid Easilocks' Shane a visit this month, though, as Geordie Shore's Vicky Pattison just debuted a whole head of copper-toned lengths and Holly Hagan went for some extra honey-hued strands to boost her sleek and chic ponytail.
Also to hit the bottle (of hair dye, duh!) this week is former TOWIE star Ferne McCann who just took her mousey brown locks a good few shades darker.
Hands up if you're currently on the phone to your hairdresser?! Guilty!
