Comedian Chris Rock’s new movie, Good Hair documents the $9 billion dollar industry catering to black women’s hair..

Rock attempts to answer the question, ‘what makes good hair?’

Released this month, Rock adds his usual humor as he speaks to regular people and celebrities—such as Ice-T, Al Sharpton and Paul Mooney to get their take on what “good hair” is, how it can be attained, and if it’s a realistic goal to have.

If you watch the video, you will see him travel to India, to see the hair extension industry. It is claimed that this is India’s largest export; I am not sure about that, but know that the majority of human hair extensions come from India.

Good Hair is released this month.
