It's no surprise that hair texture varies based on ethnic origin. But what exactly determines someone's hair texture based on their ethnic origin? In today's society, image is everything and hair is an important part of one's image. In fact, according to the 2013 Professional Salon Industry Haircare Study, total hair care industry revenue in 2013 was $64.8 billion. Since the hair industry is so profitable, it's safe to say that hair is important to many. When researching a topic about genetics or human adaptation, there are limitations in understanding the connection between human hair texture and ethnicity. Such limitations include variation in hair texture within a specific ethnicity. Since there is no uniform hair texture for each ethnicity, my research will require further digging to understand the cause. This makes it more complex to understand what determines the type of hair texture someone will have. Caucasians are a great example of an ethnicity with different hair textures as they might have straight, wavy, or curly hair. Another limitation would be the fact that everyone in the world has mixed ancestry. No human being's ethnic DNA is 100% something. This would not be possible considering the fact that humans all have a single origin, which we will talk about later. An issue that is also considered a limitation is understanding the meaning of ethnicity. Understanding whether it is a social or biological term is difficult because there is no correct answer. In Humanity: An Introduction to Cultural Anthropology by James People and Garrick Bailey, an ethnic group is defined as “a named social category of people based on perceptions of shared social experience or ancestry” (People; Bailey 389). half of the paper ......ased will either get an answer or be very close to the answer. Once the initial question is answered, perhaps hair care products can be made to work with all hair textures. By finding out exactly why hair differs between ethnicities, society can see that one should not be judged based on their hair. In conclusion, the question of how hair texture is determined within an ethnicity has yet to be resolved. However, new developments, such as evidence that all humans have the same unique origin in Africa and mutations in the P2RY5 gene can determine the structure of a human's hair, have shown that researchers are quite close in determining the structure of ethnic hair. These developments have the potential to lead to new treatments for hair removal and hair growth. The future looks bright for hair research and hopefully in the next 20-50 years the question will be answered.
