Curlier or coarser hair requires the most moisture and hydration due to its unique structural characteristics. The natural oil produced by the scalp tends to travel down the hair shaft less effectively in curlier hair types compared to straight hair. The bends and twists in the hair can prevent sebum (the natural oil) from evenly dispersing along the length of the strands, leading to dryness.

As a result, individuals with curlier or coarser hair often find that their hair is more prone to becoming dry and brittle. This necessitates a higher level of hydration and moisture to maintain softness, manageability, and overall healthy appearance. Products such as deep conditioners, leave-in treatments, and moisturizing oils are commonly recommended to keep these hair types hydrated.

In contrast, fine hair can become weighed down by excessive moisture products, straight hair typically has an easier path for the natural oils to travel along the shaft, and balding hair does not require moisture in the same way, as it lacks the structural components of hair that can become dry. Thus, curlier or coarser hair stands out as needing the most moisture and hydration.
