"Hair" portrays LGBTQ+ themes primarily through the character Woof and the song "Sodomy," which explicitly challenges societal sexual taboos. Within the film's counter-culture setting, Woof's open expression of same-sex attraction is accepted, contributing to the movie's broader message of sexual liberation and defiance against conservative norms. The overall depiction is affirming, framing diverse sexualities as part of a positive movement for freedom.

The film critiques the rigid, hypocritical, and war-supporting aspects of the American establishment, which is culturally rooted in conservative Christian values. The narrative implicitly positions these societal flaws as stemming from or being upheld by this worldview, contrasting it with the counter-culture's ideals.

The adoption of Hindu-inspired practices, such as Hare Krishna chanting, by the hippies is depicted positively. These practices are shown as integral to their peaceful, communal, and spiritually open lifestyle, which the film champions.
