My Three Sons (1960)

S6E21 Whatever Happened to Baby Chip?

Chip decides to sport a Beatle-inspired, shoulder-length hairstyle, prompting the rest of the family to believe that Steve needs to take a firmer stance with his long-haired son. Instead, Steve and his colleague turn to a company psychologist for advice. Ultimately, Steve chooses not to enforce strict rules but instead opts to provide Chip with more attention, all while remaining emotionally detached.
