The Dragons face Northampton Saints in the European Challenge Cup this Saturday (kick-off 3pm) as they look to respond to a heavy loss to league and European champions Leinster last time out.
And Fairbrother has spoken about how the players led a thorough review of the game and the determination to avoid any repeat.
“The weekend (against Leinster) was really upsetting and bitterly disappointing for all of us,” he said.
“We came in on Monday and had a player review – it's different when your peers are talking. Sometimes it's from the coaches, but when your peers are giving criticism and feedback it helps.
"It's hard to hear it from your peers but we want an honest culture. You have got to put your hand up sometimes if there are missed tackles or errors or you jump out of the system in defence.
"It's hard but you get respect for each other and make sure you don't do it again. It was good."
Backs Coach Barry Maddocks endorsed the review and stressed it was vital the players understood the way forward as they look to return to winning ways in Europe.
“It was a poor performance, so the boys have had to pick themselves up," he said.
"It was good and the boys reviewed themselves, which is needed in order for them to understand things.
"They were thorough in their review of the departments and how things went and as coaches we supported them in that process.
"We expect a reaction from the boys and they have trained really well. We are looking for a significant improvement in performance in lots of aspects.
"Of course it's about restoring pride, for the whole group – players, staff, everyone. We have to change it around for this week."
Dragons return to Rodney Parade for the final Welsh derby of 2018 against the Ospreys on December 30.
