The former Apprentice star recently gave her tresses a boost with extensions by Beauty Works, adding heaps of volume to her brunette mane.
And now the entrepreneur has switched up her 'do yet again, this time with a sugary dip-dye courtesy of ColourB4.
Luisa posted a selfie of her new barnet on Twitter yesterday (15 August), whilst posing in a sequin jumper by Pink at Victoria's Secret.
She added the caption: "Loving my pink hair, wanted to do it for ages and finally plucked up the courage!"
So why the colour change-up, you ask?
The TV star will be attending Virgin Media's V Festival this weekend, so it's only fair she has a fab new hairdo for the occasion, of course!
We love it, Luisa!
