Big Brother star Tilly Whitfield rocks brunette hairstyle in new Instagram snap

Big Brother’s youngest ‘challenge beast’ Tilly Whitfield has flaunted drastic new look, ditching one of her most recognisable features.

Big Brother star Tilly Whitfield has debuted a new look — swapping her blonde hair extensions for a bold brunette cut.

While the 21-year-old Sydneysider and ‘challenge beast’ had ditched her flowing peroxide extensions recently, over the weekend she took a step further and went for chic chocolate brown in a shaggy ‘70s style.

From blonde bombshell …

… To edgy brunette.

Tilly was vibing her new look.

The reality star has been keeping occupied during lockdown with an abundance of sizzling selfies posted to her 102,000 followers, recently stunning fans with a racy bikini shot.

Bach alum Abbie Chatfield was clearly impressed, simply posting: “UHHHH OK” beneath the snap of Tilly in a tiny pink bikini and matching sarong.

Tilly made global headlines while appearing on the latest season of Big Brother after revealing a botched beauty treatment she learned on TikTok left her blinded and scarred.

Fans had been asking Tilly why she wore a blue clay face mask on the show, so she took to Instagram to explain.

“For those asking why I have my blue clay face mask on continuously throughout the show this is what my face looked like a week prior to entering the house, hence why I always have makeup on and my skin is always covered,” wrote Tilly.

“This is the result of attempting to remove scarring I inflicted on myself trying to replicate an at-home beauty procedure I saw on a TikTok video two months before Big Brother.”

Tilly then shared photos of her red, scarred face.

The Sydneysider explained that she’d been attempting a TikTok beauty hack that involves at-home acupuncture. The procedure went so badly she ended up temporarily blinded in one eye and with severe redness on her face.

“Please please don’t try any DIY or at home beauty procedures,” warned Tilly.

“I ended up in hospital with temporary loss of vision in my eye due to swelling and was very sick from the infection, not to mention my face was somewhat unrecognisable. Leave it to the professionals.”
