"What percentage of people have curly hair" is a question that has intrigued scientists and hair enthusiasts alike. It refers to the proportion of the global population that possesses naturally curly hair, which is characterized by its coiled or wavy appearance. For instance, studies suggest that around 50-75% of the world's population has some form of curly hair.
Understanding the distribution of curly hair is not only a matter of curiosity but also has practical implications. It helps hair care companies develop targeted products, informs hairstylists about cultural preferences, and even provides insights into genetic diversity. Historically, the study of hair texture has been instrumental in the development of hair care techniques specifically designed for curly hair, such as the Curly Girl Method.
