While oily scalps tend to be the cause of dandruff, dry scalps can still bear unwanted fruit if they’re irritated and inflamed. A lot of scratching on a dry scalp can lead to falling flakes, which is why hydration and moisture are so key to a healthy micro biome. With the flake-fighting ingredients of coffee beans, ginger and green tea extract, this shampoo provides an aromatherapy-like experience.
