Vukovic is being held to a promise by peroxide-tinged winger Christian Theoharous that if the Mariners beat Melbourne Victory on Saturday in Gosford, he too will go bleach blond.
Theoharous has made a habit of sporting eye-catching styles throughout his career, and his decision to dye his hair bright blond was copied by teammates Alou Kuol and Ronald Barcellos ahead of the Mariners' semi-final win over Sydney FC.

Goalkeeper Vukovic has said he will follow suit in a gentleman's agreement that brings back memories of the Romania squad at the 1998 World Cup in France.
Theoharous wasn't even born when the likes of Georghe Hagi made headlines by celebrating their knockout-stage qualification by lathering on the peroxide, but he'd love it if his Mariners teammates mirrored his new look.
"I've heard about it (Romania), the whole team did it," Theorharous told AAP.
"I did it last year before the grand final and it worked, so if it's not broken don't fix it.
"A few of the other lads saw it and even 'Vuka' said if we win it he'll do it, so I'm on to the skipper.
"Me and him are good mates. You've got the oldest guy in the squad being mates with one of the youngest, and I think it shows the camaraderie within this squad.
"We are a tight-knit group where we don't leave anyone behind."

The Mariners are expected to sell out Saturday's grand final at Industree Group Stadium as they chase an ALM championship to add to their premiership and AFC Cup.
The club's mesmerising run under Mark Jackson is close to having a fairytale ending, even if Victory have shown on their finals journey that they will embrace the role of being party-poopers.
"It's an incredible feeling what we have in this group at the moment," Theoharous said.
"There's not really any nerves going around and we don't fear anyone.
"The togetherness and the structure we have and the coaches, Mark Jackson and (assistant) Danny Schofield, have done an unbelievable job.
"The confidence they have embedded in us (has been great) and the way they talk about football rubs off on everyone."
