Police are appealing for help to find a 25-year-old hairdresser missing since Sunday night near Warragul.

Danielle Hibbert was staying at a friend's house in Darnum when she disappeared in the middle of the night in her pyjamas and barefoot.

The 25-year-old was last seen at the house in Streitsberg Road at 11.30pm last night and was discovered missing at 7.10am this morning.

Acting Sergeant Simon Phillips, of Warragul Police, said police and the SES have scoured the property and a river near Streitsberg road for clues.

Police believe Danielle left her friend's house on her own accord.

They do not believe a third party is involved in her disappearance.

"At the moment we're hopeful, but the concern grows as time passes and she's not located," Acting Sgt Phillips said.

Danielle's disappearance has rocked her small community, and shocked friends have taken to social media to plead for her safe return.

"Everybody loves Danielle, she's so well known in the area," Danielle's boss Julie Bristol told Seven News.

"She's a big part of Bunyip, she's certainly a big part of this salon."

Danielle is about 150cm tall with a slim to medium build, fair skin and mousy blond hair.

Anyone who knows of Danielle's whereabouts is asked to call Triple 0 immediately.
