Lucy Burrows, 22, showed stylists a photo of an elaborate undercut that she had seen online.
The photo showed an elaborate tribal design etched into a model’s hair.
But her sales account manager was heartbroken when she saw what the hairdresser had actually done.
Barber n’ Bar in Cheltenham, Gloucs, at first refused to acknowledge their mishap but eventually agreed to refund the price of the £20 appointment – and even added an additional tenner as compensation.
However, half-bald Lucy, from Swindon, Wilts, is still fuming about the incident.
She said: “If you’re looking for a butcher, Barber n’ Bar is the right place.
“They absolutely destroyed my hair and confidence and I couldn’t even go to work because of this.”
“I couldn’t even go to work because of this.”
Although the hair disaster occurred in August 2018, Lucy’s hair has only just started to recover.
She said: “I still can’t wear my hair up at all and it looks so bad and messy.
“You can’t tell as much anymore but it still feels very thin to me.”
She added: “After a long argument, the hairdressers admitted they did do it to me and sent back £30 but I am still half bald which obviously isn’t great.”
This comes in the wake of a similar hairdo horror story where man in China showed his barber a video of style he was after.
Unfortunately, when the video was paused, the barber mistook the “play” symbol as part of the design and shaved a big triangle into the man’s head.
Another haircut victim was Amy Gallagher, from Kent, who was left with a style “so bad” she refused to even leave the house.
Miss Gallagher went into Supercuts in Orpington, London, for a quick trim and instead had several inches lopped unevenly out of her hair.
Barber n’ Bar have been contacted for comment.
