Marla Hayden said she cried "angry tears" when she discovered partner Jordan Deane, 30, had used "blunt" kitchen scissors to chop little Holly's hair into a "wonky" bowl-like fringe.
The 25-year-old claimed that she was forced to paste on a smile as the two-year-old happily showed off her hair to people, but admitted it took her weeks to get over the "shock" of it.
Despite Marla's pleas, Jordan took it upon himself to cut the little's one hair and then proceeded to hack off two inches when desperately trying to straighten up the wonky fringe.
The mum-of-two says Holly's hair has only now, 10 months after Jordan went to work on it, grown back long enough for a trip to the salon.
Marla, from Sudbury, Suffolk, said: "It's 100 per cent safe to say her dad is banned from cutting her hair again. It looked awful. It was a really big mess.
"I was really upset and felt really angry he'd done it. It took me a few weeks to get over the shock of it.
"I was at my mum's at the time and he took it upon himself to cut it. He didn't tell me until he picked me up. I got in the car and Holly was in her car seat. She's rear-facing and I looked in her little mirror.
"I just saw her hair and I was really upset. I said 'what have you done?' I was crying angry silent tears in the car. I was mortified," the waitress added.
"I knew the school photo was coming up with her and her brother. It'd have been their first one with her while she was at the nursery at his school.
"It took a good few months to get to a decent length and I've only just been able to take her to get it neatened up again in the last couple of weeks."
Like many people, Holly's hair had become overgrown during lockdown and Jordan felt sorry for her as it dangled in her eyes.
Taking matters into his own hands, Jordan grabbed the blunt kitchen scissors, which she uses to "cut chicken up", and began trimming Holly's hair.
"He didn't think it'd bounce up," she shared. "Because he'd cut it when it was wet, it didn't look right. He kept going and going.
"When it dried, it was the length you can see in the picture. It made her look really weird looking - like an alien. Like Star Trek.
"He knew he'd messed up. He even said 'let's not overthink, it's only hair. I know I've made a mistake. I'm not going to do it again'. Bless him."
After Marla had given Jordan a telling off, the mortified dad realised he'd make a mistake and vowed never to play hairdresser again.
The following day Marla was forced to take Holly into nursery and pre-warn staff about the trimming mishap - although the little one was only delighted with her dad's haircut and kept showing it off.
Marla said: "She was quite happy with it and said 'Daddy's done my hair - do you like it?' I was like 'yeah, really like it' pretending, secretly thinking 'what have you done?'
"She kept showing it off to people and saying 'look what Daddy's done'. I just had to pretend and say 'yeah, lovely isn't it'.
"I was thinking 'oh, it's the first picture of them together at the same school soon', but luckily by the time the photo came, it'd grown just enough to put a little clip in. It didn't look too bad by then but it still looked quite bad."
