Memphis is the closest large city to Jefferson, and often appears in the Yoknapatawpha fictions. Both Susan Reed and, presumably, the narrator travel to "a hospital in Memphis" for different kinds of treatment (144). And when Hawkshaw regularly disappears from town with the money he's been saving, other men assume he is spending it "among the fleshpots of Memphis" (141) - a reference to the city's many bars and brothels.
Although characters live in a number of Jefferson boarding houses throughout the Yoknapatawpha fictions, "Mrs. Cowan's," where both Hawkshaw and Mitch Ewing live, only appears in this one story (142). Faulkner's boarding houses are typically run by women, but only provide room and board to single men.
Elsewhere in the Yoknapatawpha fictions Faulkner describes Gavin Stevens' office and its location on Courthouse Square in some detail. All the narrator of "Hair" says is that he went "to Stevens' office" in Jefferson (145).
The "soda fountain" is mentioned only as one of the places in town which the "young fellows" can watch "the young girls" going to in "the late afternoon," presumably after school lets out (141). A "soda fountain" serves ice cream and carbonated drinks; typically it consists of a long counter, with perhaps a few tables and chairs. During Faulkner's lifetime, and in a number of his fictions, "soda fountains" are found in drugstores.
The "post office" is mentioned only as one of the places in town where the "young fellows" can watch "the young girls" going to in "the late afternoon," presumably after school lets out (141).
Not long after arriving in Jefferson, Hawkshaw "joins the church" (141), and apparently goes there "on Sunday" with regularity (143), but the story provides no cues about the denomination. Protestant churches are common feature of the landscape, both physical and cultural, in Faulkner's Yoknapatawpha; the most common denominations are Episcopalian, Methodist, Presbyterian and Baptist.
The narrator suggests that Maxey's barber shop is a typical "three-chair country shop" (141). Jefferson barber shops appear in a number of Yoknapatawpha fictions. (In "Dry September," which was published four months before "Hair," the barber shop is even owned by Hawkshaw, who in this story works for the owner, Maxey.) Typically Faulkner's barber shops are all-male environments, though no one in this story seems to see anything unusual about the fact that Susan Reed gets her hair cut there as both a girl and a young woman.
"The square" that the narrator sees outside the window of Maxey's barbershop and in which Hawkshaw "walks about" after first arriving in Jefferson (137, 141) is the same one that Faulkner's fictions usually call "courthouse square." (In the the Vintage edition of the Collected Stories, the "courthouse" is not mentioned - but it should be.
The Jefferson railroad station appears in many of Faulkner's works as the portal that provides Jefferson's main connection to the larger world. The way Hawkshaw arrives in town by "getting off the south-bound train" (137) and then leaves each year by getting on a train going north to the "junction-point" (143) is typical.
