James Vaughan had briefly put new Terriers boss Mark Robins on course for his maiden win but that was about as good as it got at the City Ground.
Robins faces a daunting rescue mission after watching Town slump to 21st place in the Championship table, just two points clear of the relegation places.
The former Rotherham and Barnsley boss was lured from Coventry after turning the League One club's fortunes around in a short period and the mission at Huddersfield is the same, but time is running out.
He said: "It's the most embarrassed I've been as a manager.
"I can't believe how naive we've been, if you want to pass the ball then that's fine but you've got to win your battles.
"You try not to overreact to a defeat but we need to be picking points up. It started off so well and ended up as it did but we need to pick ourselves up for Ipswich (on Saturday).
"We've got 14 games left and we need to start picking points up because we're in the thick of a relegation scrap."
