This is an interesting article about hair straightening, culture and race written in the Miami Herald from 2007. Here are a few quotes from the article:
"Nearly all Dominican women straighten their hair, which experts say is a direct result of a historical learned rejection of all things black."
"I always associated black with ugly. I was too dark and didn't have nice hair," said Catherine de la Rosa, a dark-skinned Dominican-American college student spending a semester here. "With time passing, I see I'm not black. I'm Latina."
"A walk down city streets shows a country where blacks and dark-skinned people vastly outnumber whites, and most estimates say that 90 percent of Dominicans are black or of mixed race. Yet census figures say only 11 percent of the country's nine million people are black. To many Dominicans, to be black is to be Haitian. So dark-skinned Dominicans tend to describe themselves as any of the dozen or so racial categories that date back hundreds of years -- Indian, burned Indian, dirty Indian, washed Indian, dark Indian, cinnamon, moreno or mulatto, but rarely negro."
