Curly hair is not rare. While it's not the most common hair type, a significant percentage of the population has naturally curly hair. Although estimates vary, sources indicate that less than 20% of people have naturally curly hair. This means that a large portion of the population still has curls.
It's important to note that the prevalence of curly hair can vary depending on ethnicity and geographic location. For example, some sources suggest that a higher percentage of people of European descent have curly hair compared to those of East Asian descent.
Furthermore, many people with straight hair might have a slight wave or texture, which can be considered a type of curl. Straight hair without any wave or texture is actually considered more rare.
In conclusion, while not the most common hair type, curly hair is far from being rare.
