The Ingredient

What Is Sodium Hyaluronate?

Sodium Hyaluronate helps create the hydrated follicular environment required for healthy scalp function, dermal papilla survival, and optimal hair growth activity.

Sodium Hyaluronate is the salt form of hyaluronic acid — a naturally occurring glycosaminoglycan found throughout the body, including the scalp dermis and extracellular matrix surrounding hair follicles.

It is one of the most powerful biological humectants known, capable of holding up to 6,000 times its weight in water and maintaining hydration within scalp tissue.

Healthy follicles require a hydrated dermal environment for proper nutrient exchange, extracellular matrix stability, and protection against inflammatory stress.

Sodium Hyaluronate has a smaller molecular size than standard hyaluronic acid, allowing deeper penetration into the scalp and improved access to the follicular environment.

Research shows hyaluronic acid interacts with CD44 receptors expressed on dermal papilla cells — the follicle structures responsible for regulating hair cycling and growth activity.

In the HAIRLOVE Scalp Serum, Sodium Hyaluronate helps hydrate and soothe the scalp while enhancing the performance and penetration of the serum's other active ingredients.

Key Benefits

Extreme Water Retention Capacity Holds up to 6,000 times its weight in water to maintain scalp hydration.

Smaller Molecular Weight Penetrates deeper into scalp tissue compared to traditional hyaluronic acid.

Supports Dermal Papilla Cells Interacts with CD44 receptors involved in follicle cell survival and signaling.

Reduces Dryness & Irritation Helps calm flaking, dryness, and inflammatory scalp stress.

Enhances Active Ingredient Delivery Supports the absorption and performance of the Scalp Serum's other actives.

Suitable For Sensitive Scalps Well tolerated and non-irritating across all scalp and hair types.

Editor's Note

Sodium Hyaluronate is more than a cosmetic hydrator — the CD44 receptor interaction gives it direct relevance to follicle biology and scalp resilience under inflammatory stress.
