"Hair by Mr. Bean of London" is the fourteenth episode of the television series Mr. Bean, and was produced by Tiger Aspect Productions in 1995. It was first released in VHS as a video exclusive "unseen episode" on 15 November 1995, but was not aired on television until 2006.

Bean goes to Derrick's barber shop for a haircut. After choosing what hair style he wants (by pointing to a calendar of Prince Charles), the barber attempts to make the first snip, but is unable to do so as Bean keeps tilting his head forward so he can read a magazine. The office phone then starts to ring, and Derrick reluctantly goes to answer it. All alone, Bean entertains himself by pretending to give someone a haircut, until two customers come in and assume Bean is a hairdresser. The first customer is a young boy and his mother leaves him in Bean's care as she runs to retrieve her purse she left at the shop. Bean places a bowl over the boy's head and cuts his messy shoulder length hair into a bowl hairstyle. He then accidentally shaves off a small piece of the boy's hair while trying to use a razor, and ends up shaving a bald stripe down the middle of his head to even it out. Although it looks ridiculous, the boy is satisfied with his new hairstyle.

After the boy's mother returns and pays Bean for the haircut, he returns to his seat just as Derrick returns from the phone, only for it to ring again. Bean then resumes being the substitute hairdresser, his next customer being a man with a ponytail (which apparently took over two and a half years to form). While trimming the ponytail, Bean becomes distracted by the magazine the man is reading and unintentionally severs it. After he finishes, Bean uses a portrait of a ponytailed man instead of a mirror to deceive him and the man leaves, unaware that his real ponytail has gone.

Bean's final customer is Roger, a man who is purportedly a regular at Derrick's. After taking off his glasses, Roger mistakes Bean for Derrick due to his poor eyesight and asks for his "usual" haircut. Bean then proceeds to use the razor but, despite being as careful as he can, accidentally shaves off Roger's toupee causing it to get stuck in the razor. He remedies it by applying mousse on Roger's bald spot and using bits of hair from the floor to create a new "toupee". Derrick finally returns from his phone call just Roger pays him and leaves, and Derrick's initial confusion intensifies when the mother of the boy from earlier and the man with the ponytail storm in and demand to know where his supposed assistant (who is none other than Bean himself) is as they hate the terrible haircuts he gave them (even though the boy continues to insist that he likes his).
