'Parenthood': Kristina Makes A Dramatic Decision While Battling Cancer (VIDEO)

NBC wasted no time jumping into the final four episodes of Season 4 of "Parenthood." The New Year kicked off with a new look for Kristina, who made a bold decision in her battle with cancer. After realizing that the chemotherapy was starting to take her hair, Kristina decided to take matters into her own hand and she shaved her head.

"It’s one thing [for you] to know that you have something, but it’s another to walk around and have everybody in the world know," showrunner Jason Katims told TVLine.

After Adam was shocked upon seeing his wife without hair, Kristina blew up at him and then tried to make amends by getting all gussied up (wig included) and planning a date night. Her new red locks attracted the attention of a younger man, which helped Kristina feel better about the situation.

There are no easy answers when it comes to cancer, and in true "Parenthood" fashion, the show simply showed the complexities of what the characters are going through, and kept it as real as possible.

Monica Potter, who plays Kristina, told HuffPost TV that the episode is her favorite, partly because Dax Sherpard, who plays Crosby on "Parenthood," directed it. "There's not one flat line of emotion," Potter said of Tuesday's episode. "It's everywhere."

Season 4 of "Parenthood" moves toward its conclusion in three weeks, Tuesdays at 10 p.m. EST on NBC.
