A Liverpool fan grew his hair long and shaggy, refusing to get a haircut until his beloved Reds lost a match.
Luke Stangroom, 43, made the pledge after watching his team win the Champions League in June last year.
He said he would not get a haircut until Liverpool's next Premier League defeat.
The Reds unbeaten run saw the dad-of-three's hair become longer than ever.
But forklift driver Luke, from Norwich, had to say goodbye to his “scruffy looking” ponytail-length hair following Liverpool's 3-0 loss against Watford on Saturday.
Luke said: “I’ve been a skinhead for as long as I can remember now because I’m receding quite badly.
“Winning the Champions League was one of the best moments I’ve ever had as a fan. It was right up there.
“I watched the pub at my local and after the match said to a mate that I’m not going to get a haircut until they next lose a match.
“It was only a joke and to be honest I only thought it would last a couple months.
“But it just kept going on and on and it became a running joke.
“I got used to the longer hair and I wanted Liverpool to keep winning but towards the end I was secretly wanting to have a haircut quite badly.
“The hair started to do my head in. I kept having to tuck it behind my ears and I didn’t really like it.”
Luke, who has a partner, cleaner Michelle Cameron, 43, said he decided to shave his head in his early 30s.
But he went from shaving his hair on a weekly basis to not cutting it at all for nine months, after the pub promise on June 1.
By this point Liverpool were already 17 games unbeaten in the Premier League - a run they would go on to extend by a further 27 games.
The remarkable run of form - which almost broke Arsenal’s historic 49 game unbeaten run set in 2004 - finally came to an end on Saturday.
Luke went to the hairdressers on Sunday morning.
But instead of going back to being a "skinhead", he said he chose to go for a short, back and sides instead.
Luke said: “Obviously I never want Liverpool to lose by I was pretty pleased to be able to get a haircut.
“Michelle was OK with the hair but even I’ll admit it did look a bit of a mess.
“I was quite pleased to stick to my words and it did feel odd.
“I never once regretted saying I’d do it. I was prepared to grow my hair for as long as it took."
