Your scalp’s microbiome is a natural ecosystem made up of many different types of microorganisms. When bad microorganisms begin to outnumber the good ones, that imbalance can lead to irritation and flaking associated with dry scalp.

A hyaluronic-acid-based Molecular Patch delivers instant soothing and sustained hydration to the scalp. To provide lasting relief from itchiness, irritation, and flaking from dry scalp, Restore Dry Scalp Treatment utilizes a vitamin B3 based microbiome balancing complex with clinically proven actives that support the beneficial microorganisms on your scalp by rebalancing its natural ecosystem.

This product cruelty-free, color-safe, safe for chemically-treated hair, and formulated without silicone, GMOs, and residue.
