Which hair type generally requires more moisture?

Curly hair generally requires more moisture due to its structure and the way it interacts with natural oils produced by the scalp. The twists and bends in curly hair can make it challenging for the oils to travel down the hair shaft, leading to dryness. This hair type tends to be more porous, meaning it loses moisture more readily than other hair types. Because of its texture, curly hair often benefits from hydrating products that can help retain moisture and prevent frizz, making regular conditioning essential.

In contrast, straight hair typically allows natural oils to distribute more evenly from the scalp down the length of the hair, which can help keep it hydrated without needing as much additional moisture. Fine hair, while it can become easily weighed down by heavy products, often requires lightweight moisture to prevent limpness. Coarse hair, on the other hand, while it can also be dry, usually has a higher tolerance for hydration and may not need as frequent moisturizing as curly hair. Therefore, curly hair stands out as the type that needs the most moisture to maintain health and manageability.
