One of the easiest ways to show that a male character has fallen into depression is to show him with unkempt stubble or sometimes even a full beard after a Time Skip.
Happens to be Truth in Television, of course. A common symptom of depression is loss of interest in personal appearance; and in men this might cause them to quit shaving. This is frequently accompanied by the Drowning My Sorrows trope.

This wasn't so much because he was depressed as because he had been searching for weeks nonstop and just hadn't taken the time to shave. (The beard looked pretty awesome actually, since Thor arguably shouldn't be clean-shaven in the first place.)
Flycatcher in Fables grows a massive orange beard whilst mourning his lost family. He later implies that he hadn't even noticed it.

In The Butterfly Effect it's subtly used, but there. In the futures that Evan loses Kayleigh in he's always grown out a full beard.

He was degenerating visibly, under the eyes of all. He had entirely lost the almost foppish concern for his appearance, and was grown careless and slovenly in his dress. He allowed a black beard to grow on cheeks that had ever been so carefully shaven; and the long, thick black hair, once so sedulously curled, hung now in a lank, untidy mane about a face that was changing from its vigorous swarthiness to an unhealthy sallow, whilst the blue eyes, that had been so vivid and compelling, were now dull and lackluster.

He removes it at the end of the book—not shaves it, but uses his magic to make it not exist—at the end when he reunites with Kahlan and all is forgiven.

The Shield: Actor David Rees Snell, who played "Ronnie Gardocki" on "The Shield", upgraded in his trademark moustache to a full-fledged beard in between seasons two and three of the series (largely to sidestep the issue of his character being brutally disfigured in season two by having a beard cover up where his scars were). The character shaved off the beard midway through season six, to please a new girlfriend of his, but after finding out that fellow Strike Team member Shane Vendrell had not only murdered Ronnie's friend Lem, and had exposed Vic and Ronnie's involvement in robbing several million dollars from a local crime syndicate's money laundering ring, the beard came back for revenge as Ronnie sought (unsuccessfully) to save himself from being destroyed by Shane and Vic's war.

He kept it up for the rest of the series, too- this was The Stubble That Would Not Die. According to the Season 6 comics, not even when its owner did. It was part of Wesley's character development, a visual aid to his newly acquired badassery. Alexis Denisof once commented in one of the episode commentaries how difficult it was to maintain the stubble rather than either keeping clean-shaven or just actually growing a full beard. This was also Lampshaded in the memory-loss ep. "Spin The Bottle", where Wesley, who, along with the rest of the gang has woken up thinking he is in high school after a memory spell goes awry, scratches his chin thoughtfully and remarks "I seem to have grown about three days' worth of beard."
There's a triple example during the New Caprica story arc. After the Time Skip humanity is doing pretty crappy and both Saul Tigh and Chief Tyrol sport big scruffy beards while Admiral Adama had a case of a mustache of sorrow. They all lose their facial hair around the same time when the status quo is returned and they're able to leave the planet. Starbuck can also be said to have grown Long Hair of Sorrow during the same arc, while Apollo leaves his hair untampered with but has the Weight Gain of Sorrow to show his misery after Starbuck leaves him, marries Anders, and she and Apollo stop being friends, both of which also go away quickly after they're back on Galactica.
