Alternate reality
Perfect Hair was a disparaging nickname for James T. Kirk given by an intoxicated Montgomery Scott in 2259.
After having been "fired" by Kirk, Scott visited the Port of San Francisco bar with Keenser. While there, he referred to Kirk as "James Tiberius Perfect Hair" when the captain contacted him from the USS Enterprise, requesting his assistance. He then asked Keenser if he had heard the engineer insult Kirk thusly in the captain's hearing. (Star Trek Into Darkness)
