ethnic identity, wealth and rank within the community (see Byrd & Tharps, 2001; Jacobs-Huey, 2006; Mercer, 1994; Patton, 2006; Rooks, 1996). For young black girls, Thompson says, "hair is not just something to play with" – it is something that sends a message, not only to the outside public but also a message on how they see themselves. "In the 1800s and early 1900s, nappy, kinky, curly hair was deemed inferior, ugly and unkempt in comparison with the flowing, bouncy hair of people from other cultures", says Marcia Wade Talbert in Black Enterprise. Chemical relaxers increased in demand throughout the 1800s and 1900s. These relaxers often contained sodium hydroxide (lye) or guanidine hydroxide which result in hair breakage, thinning of the hair, slowing of hair growth, scalp damage and even hair loss, according to Gheni Platenurg in the article, "Black Women Returning to Their Natural Hair Roots". In the United States, the successes of the civil rights movement, and the Black power and Black pride movements of the 1960s and 1970s, inspired African-Americans to express their political commitments by adopting more traditionally African styles. The Afro hairstyle developed as an affirmation of Black African heritage, expressed by the phrase, "Black is beautiful." Angela Davis wore her Afro as a political statement and started a movement toward natural hair. This movement influenced a generation, including celebrities like Diana Ross, whose Jheri curls took over the 1980s. Since the late 20th century, Black people have experimented with a variety of styles, including cornrows, locks, braiding, hair twists and short, cropped hair, specifically designed for kinky hair. Natural hair blogs include Black Girl Long Hair (BGLH), Curly Nikki and Afro Hair Club. With the emergence of hip-hop culture and Jamaican influences like reggae music, more non-Black people have begun to wear these hairstyles as well. A new market has developed in such hair products as "Out of Africa" shampoo. The popularity of natural hair has waxed and waned. In the early 21st century, a significant percentage of African-American women still straighten their hair with relaxers of some kind (either heat- or chemical-based). This is done despite the fact that prolonged application of such chemicals (or heat) can result in overprocessing, breakage and thinning of the hair. Rooks (1996) argues that hair-care products designed to straighten hair, which have been marketed by white-owned companies in African American publications since the 1830s, represent unrealistic and
