Can other ethnicities of hair be used? Why is the focus solely on Afro hair?
Thank you Ms. Brown for your question. One of the stipulation requirements by the (NSF) National Science Foundation is to use a chemical-free product. This factor excluded women, whom were likely to use chemicals, dyes, etc. In the Black culture, typically the women and men would not receive services in the same location. The women receive hair services at the beauty shop, and men receive services at barber shops. Collecting hair bins from shops were men and women received services in the same location posed the issue of collecting bins with hair that had received chemical services. Other contributing factors is Afro hair contains an elliptic structure(4C) that renders greater holding water-holding capacity, and cross linking properties.
