Here's why it's a tricky question:
* Genetics: Hair texture is primarily determined by genetics. Different ethnic groups have a higher prevalence of certain hair types, but there's significant individual variation within each group.
* Geography: While some regions may have higher concentrations of specific hair types due to historical migration patterns, it's not possible to generalize to an entire country or continent.
* Cultural influences: Hairstyles and hair treatments can also influence how curly hair is perceived and presented.
Instead of focusing on where most women have curly hair, it's more interesting to consider the diversity of hair types worldwide and the cultural significance of different hair textures.
