What is hydration in the context of hair health?
Hydration refers to maintaining adequate moisture levels in the body and scalp, which is critical for overall skin integrity and hair fiber resilience.
Dryness can weaken the scalp barrier, reduce elasticity, and contribute to inflammation or irritation. Dehydration may also impair nutrient transport and follicular energy metabolism.
While red light therapy doesn't directly hydrate the scalp, it supports microcirculation and cell repair, which can enhance the scalp’s ability to retain moisture and support healthy follicle environments.
