Which hair type requires more moisture due to its structure?

Curly hair requires more moisture due to its unique structure, which is characterized by its twists and turns. The shape of the hair follicle and the disulfide bonds in curly hair create a pattern that makes it more porous compared to straight or wavy hair types. As a result, curly hair can lose moisture more easily, leading to frizz and dryness if not adequately hydrated.

Additionally, the bends and curls in the hair prevent natural oils from traveling down the hair shaft as effectively as they do in straighter strands. This necessitates a consistent moisture routine to keep curly hair healthy, shiny, and manageable.

In contrast, straight and wavy hair generally have a smoother surface that allows for better moisture retention, while coily hair, while also needing moisture, has a bit more structural resilience due to its tighter curl pattern but still benefits significantly from proper hydration. Therefore, maintaining moisture is particularly crucial for the health and appearance of curly hair.
