Common Sense Note
Parents need to know that this Chris Rock documentary includes some mature themes related to race, femininity, and class. There's a fair amount of strong language (a couple of "f--k"s, as well as "s--t," "bitch," and the like), conversations about how hair affects sexual relationships, and consumerism (mostly hair-product brands). Kids will see two approaches -- African-American celebrities like Eve, Raven Symone, and Nia Long are straight up about masking their natural hair with expensive weaves, while a few outspoken women rage against the "slavery" of a straightening regime and sport their natural locks (or, in one case, a bald head).
Sexual
Content
Candid conversation about what it's like for men to make love to a woman with a weave (including tips on which positions are best for men not to be tempted to touch their partners' hair -- references include terms like "doggy style"). Plenty of cleavage; women wearing lingerie and bikinis walk around at the hair show, and photos of topless African women are shown briefly during a slideshow of how black women's hairstyles have changed throughout the ages.
Violence
It's not violent, but there's a disturbing description of what a chemical burn caused by a chemical relaxer feels and looks like.
Language
Occasional (but not frequent) strong language like "f--k," "s--t," "bitch," and the "N" word, as well as "ass," "titties," "damn," "hell," and "oh my God."
Social
Behavior
The movie has a positive message about how natural hair can bring "freedom," but most of the interviewees admit that they've bought completely into the idea that they must change their hairstyle in order to be attractive -- even if it means spending lots of money and time to do it.
Consumerism
Mostly hair products and related industry brands: Bronner Brothers, Dudley hair products, Revlon, Loreal, etc.
Drugs / Tobacco /
Alcohol
Jokes about how hair treatments are more addictive than crack or "the pipe."
