With all the extensions and the constant back-and-forth from redhead to blonde, Lindsay Lohan's hair has been put under a lot of pressure, and it was certainly showing signs of it yesterday.

The actress was sporting a bald patch on the back of her head as she stepped out last night.

Her extensions had been given as much love and attention as Britney gave hers circa 2008, and looked poorly maintained as she arrived at E.Baldi restaurant in Beverly Hills to grab a takeaway.

Balding due to the use of extensions (medically known as traction alopecia) is pretty common, and other celebs who have experienced bald patches include Katie Price, TOWIE's Jess Wright and Rihanna.

Earlier in the week, LiLo - who is currently filming her role as Elizabeth Taylor in a remake of Liz & Dick - enjoyed a sleepover with Lady Gaga and Lana Del Ray.

The trio enjoyed a night at the Château Marmont hotel in LA, and Gaga was seen posting on Twitter about Lindsay's odd diet.

She wrote: '@lindsaylohan when you ordered a cucumber and a knife to the bar last night i thought your were gonna perform a vasectomy #justaskinnyb***h.

Get a pie down you love!
