I saw that documentary. Very informative and entertaining. It didn't hurt that the women were stunning too.A very good documentary named "Good Hair", made several years ago, was discussing the propensity/culture of the black women, who at a very early age are trying to straighten their hair and, in the process, are damaging it so much over the years that they have to wear wigs for the rest of their life.
Name of the person who produced/helmed this documentary?...Chris Rock!!
