Product Overview & Review
The Nutrafol Root Purifier Shampoo is designed for people with thinning hair who want a gentle shampoo that supports a healthy scalp environment. Its formula deeply cleanses excess oil and buildup without stripping the scalp, making it gentle enough for daily use.
The formula contains prebiotics, vegan proteins, Australian wild berries and a bio-based cleanser. These ingredients help hydrate and nourish the scalp and hair while supporting a balanced scalp environment.
Nutrafol states that the shampoo is clinically tested and can visibly improve hair volume, strength and texture. It is also color-safe and formulated without parabens, phthalates, silicones, sulfates or synthetic fragrance.
The shampoo is suitable for regular cleansing and is especially useful for users dealing with thinning-looking hair, excess scalp oil or dryness. However, Nutrafol clarifies that its scalp-care shampoo is designed to support scalp and hair health rather than directly grow new hair.
