Hydration is crucial for scalp health primarily because it helps prevent dryness and flakiness. When the scalp is adequately hydrated, it maintains a balanced moisture level, which supports the natural function of the skin on the scalp. Insufficient hydration can lead to dry skin, resulting in irritation, itchiness, and the formation of dandruff or flakes. By ensuring that the scalp is well-hydrated, you create a healthy environment that supports both the scalp and hair follicles, ultimately promoting better hair health and a more comfortable scalp.
Additionally, while hydration may have secondary effects on issues like hair breakage and growth, the primary function of hydration directly relates to maintaining skin health on the scalp. This foundational aspect of scalp care is vital for preventing problems that stem from dryness.
