A postie said she couldn't face doing her rounds after an "embarrassing" haircut.
Rachel White, 20, spent £65 and four and a half hours having her locks cut and coloured at Arista Hair and Beauty salon in Nelson, South Wales.
But when she got home her cousin was shocked at the style and told her to go and look in the mirror.
Rachel was horrified to see long strands of hair hanging down from the blunt and wonky cut.
Her cousin had to trim her hair before she would go to work to complete her postal rounds.

Rachel admits she didn't check her hair before she left, saying: "I didn't think twice about not looking at the result because I'd been in there so long."
She added: "I'd only asked for a trim so wasn't expecting to see much change but as soon as I got home my cousin said: "You need to look in the mirror, your hair isn't even."
"So I washed it first and styled it my own way but there was no denying how bad the hair cut was."

Outraged, she decided to share snaps of her haircut on Facebook .
Rachel, of Edwardsville, Merthyr Tydfil, said: "I posted the worst pictures to warn others about my terrible experience.
"I received a message from the salon telling me to come back and they'd fix it but they didn't apologise.
"No way was I going back there."
Staff at another salon nearby offered to fix her hair for free but the original cut and the correction means the style is now much shorter than she wanted.
She said: "Aura were kind to help and they have done well to fix what they could but I've had to have so much cut off I'm still so unhappy.
"My hair is now about 3 inches shorter than what I asked for.
"I won’t be able to wear my hair down for a very long time as it's embarrassing.
