Judging from the audience reaction at the press screening of Chris Rock's "Good Hair," HBO should look to air the documentary, a commentary by Rock (interviewed on video earlier) on the industry and mindset of African-American hair, as soon as possible. Snickers, guffaws, gasps, nods of agreement, winces and cheers arose from the industry crowd as Rock, with a cavalcade of stars including Nia Long, Ice-T, the Rev. Al Sharpton, video vixen Melyssa Ford and Dr. Maya Angelou, commented on personal and societal rules when dealing with black hair. Especially that of a black woman.
