Curly hair typically requires more moisture due to its unique structure and the way it retains natural oils. Curly hair shafts have bends and twists that make it difficult for the scalp's natural oils to travel down the length of the hair. This results in dryness, as the oils may not reach the ends of the hair strands. The curl pattern also tends to create more surface area, which can lead to increased moisture loss through evaporation. Hence, individuals with curly hair often benefit from hydrating products such as conditioners, leave-in treatments, and oils to maintain moisture levels and enhance the curl's appearance.

In contrast, straight hair generally allows oils to flow more easily down the hair shaft, leading to a more uniform distribution and less need for added moisture. Wavy hair falls somewhere in between, depending on how tightly the waves form, while coarse hair may also require moisture, but its thickness can retain moisture better than fine or curly hair. Therefore, curly hair stands out as the texture that most distinctly requires additional moisture to maintain health and manageability.
