Red Seal Cosmetology Practice Exam

Out of the four options given, the best answer is Asia. This is because Asia, particularly countries like China and India, are the main suppliers of human hair in the hair industry. They have a long history of producing and exporting human hair, with China being the largest exporter in the world. While Europe and North America also produce human hair, they are not the primary sources and do not supply as much as Asia. South America is also not a major contributor to the global human hair market. Therefore, out of the four options, C, Asia, is the most accurate and suitable answer.
