What Percentage of the World Population Has Curly Hair?
Curly hair is a unique and beautiful trait that many people around the world possess. However, it is interesting to delve into the statistics and understand what percentage of the global population actually has curly hair. In this article, we will explore the varying factors that contribute to curly hair and attempt to determine the approximate percentage of individuals worldwide who have this characteristic.
Factors Influencing Curly Hair
Curly hair is primarily determined by genetics. Several genes play a role in determining the texture and curl pattern of an individual’s hair. Two key genes that influence hair curliness are the KRT75 and TCHH genes. Variations in these genes can result in different curl patterns ranging from loose waves to tight coils.
Ethnicity also plays a significant role in determining hair texture. People of African, Afro-Caribbean, and Afro-Latinx descent are more likely to have naturally curly or coily hair. On the other hand, those of European, Asian, or Indigenous American descent tend to have straighter or wavy hair. However, it is important to note that hair textures can vary within each ethnic group due to genetic diversity.
Percentage of World Population with Curly Hair
Determining the exact percentage of the world population with curly hair is challenging due to the lack of comprehensive global data. However, it is estimated that approximately 15-20% of the global population has naturally curly hair. This percentage may vary depending on factors such as geographic location, ethnicity, and the definition of what is considered “curly hair”.
