What Percentage Of The World Has Curly Hair?
Curly hair is a distinctive hair type characterized by its naturally curly or wavy texture. Many people wonder about the prevalence of curly hair worldwide and the factors that contribute to its occurrence. In this article, we will explore the genetics, variations, prevalence, regional differences, and factors that influence curly hair. We will also discuss the curly hair market and share some final thoughts on this unique hair type.
Defining Curly Hair
Curly hair is categorized by its spiral or wave-like texture, which differs from straight or wavy hair. It is a result of the shape of the hair follicle, which is more oval or elliptical rather than round, causing the hair to curve as it grows. Curly hair can range from loose curls and waves to tight coils, encompassing a wide range of unique textures and patterns.
Genetics and Curly Hair
The occurrence of curly hair is primarily determined by genetics. Specific genetic variations influence the shape of the hair follicle, resulting in curly or straight hair. The gene responsible for curly hair is called the Trichohyalin gene (TCHH), and variations in this gene can lead to different degrees of curliness.
Variations in Curly Hair
Curly hair is not a one-size-fits-all category. It varies significantly in terms of texture, curl pattern, and thickness. Hair textures can range from fine to coarse, and curl patterns can be categorized into various types, such as Type 2 (wavy), Type 3 (curly), and Type 4 (coily). Within these categories, there are further subtypes that differentiate between the intensity and shape of the curls.
Prevalence of Curly Hair Worldwide
Estimating the exact percentage of the population with curly hair worldwide is challenging since it depends on various factors such as ethnic background, geographical location, and individual genetic makeup. However, studies suggest that approximately 55% of people globally have some degree of curl or wave in their hair. This indicates that curly hair is relatively common and diverse in its prevalence.
Regional Variations
Curly hair prevalence exhibits regional variations due to genetic and environmental factors. For example, individuals with African or Afro-Caribbean ancestry are more likely to have naturally tight and coily curls. The global distribution of curly hair is influenced by population mixing, migration patterns, and historical factors. Some regions, such as Latin America and parts of Europe, have higher percentages of curly-haired individuals compared to others.
Ethnicity and Curly Hair
Ethnicity plays a significant role in determining the prevalence of curly hair. People of African, Afro-Caribbean, and Mediterranean descent are more likely to have naturally curly or wavy hair. This is attributed to the genetic traits passed down through generations, which contribute to the formation of the hair follicle and the resulting curly texture.
Factors Influencing Curly Hair
In addition to genetics, several environmental factors and hair care practices can impact the appearance and health of curly hair. Factors such as humidity, temperature, moisture levels, and styling techniques can affect the intensity of curls and frizz. Additionally, the use of heat styling tools, chemical treatments, and certain hair care products can alter the natural pattern of curly hair.
Hair Texture and Curl Patterns
As mentioned earlier, curly hair encompasses a wide range of textures and curl patterns. These variations influence how curly hair responds to different hair care practices and the types of products that work best. Understanding one’s hair texture and curl pattern is crucial in developing a personalized hair care routine to enhance and maintain the natural beauty of curly locks.

The diversity and prevalence of curly hair have led to an expanding market catering specifically to the needs and preferences of curly-haired individuals. There are many hair care brands that offer specialized products tailored to different curl types, providing moisturizing, defining, and styling solutions. This market offers a range of options to help people embrace and care for their curly hair.
