An impromptu twist to the World’s Greatest Shave has left the Warrnambool man sporting half a beard and half a head of hair for the past week.

Midway through the shave on Friday at the Flying Horse Bar & Brewery, a friend suggested he could raise even more money with the unfinished haircut.

“A mate yelled out ‘if you leave it like that for a week I’ll give you $500’,” he told The Standard.

“I said I’d do it for $1000.”

A minute later the total was raised, leaving the 27-year-old looking, in his own words, “like an idiot”.

“People definitely do a double-take. I made a small child cry at the supermarket.

“There was a kid 10 or 12 who did a double-take and walked into the end of an aisle.

“I don’t normally wear hats but I’ve been trying to hide it the best I can.”

Tomorrow the rest of Mr Noonan’s locks and facial growth will be gone — and he says it’s not a moment too soon.

“I’ve been growing my hair and beard for nearly eight months now, so it’s quite long and mangy to say the least.

“I usually have it shaved so it’s been weird having to wash my hair.

“I just sort of had my own issues going on for a while and thought there’s a lot of people worse off than I am.

“The Shave For A Cure seemed like a really good option.”

As expected, he’s copped a share of jokes this week but the final result is $1600 for cancer research.

“Most people have been really supportive. All up I’ve raised just a little under $1600 and my goal at the start was $500.”
