Hendon slipped to a third consecutive defeat at Cherrywood Road as Farnborough won 3-0.
Although the home side created the better chances the game turned just after the half hour mark as Christian Smith was adjudged to have hauled down a Farnborough forward and was dismissed.
Paul Hodges opened the scoring a couple of minutes before the break with a well taken goal, and then Sam Deering made it 2-0 midway through the second half.
Elijah Simpson added a third with five minutes remaining to sink the hard-working Greens and secure the three points.
