TOMMY GUN'S Original Barbershop slashed the price of its hair cuts today, in a bid to raise money for prostate cancer.

The price of the classic cut was $15, with $10 donated to the Movember Foundation to support testicular cancer - the second most common cancer in men aged 18 to 39.

To maximise funds raised, the classic cut was the only service offered.

Men lined up from the moment the store at Grand Central opened, ready to get a hair cut and support men's cancer research.

Tommy Gun's first supported Movember in 2016, raising $11,371 for the foundation with its cut price haircuts.

The aim was to raise more than $20,000 across the nation this year.

Movember Foundation country director Charlotte Webb said she was thrilled to see Tommy Gun's back on board in 2017 and going the extra mile to stop men dying too young.

"With rates of testicular cancer diagnoses doubling in the past 50 years, it's critical we reach young men early and encourage them to to go to a doctor if they notice any changes in size or shape,” she said.
