Nioxin System 3 Thickening Shampoo for Colored, Dry & Damaged Hair

In this review of Nioxin System 3 Scalp + Hair Thickening Shampoo the bottom line is simple: it is best suited for people with fine, light thinning hair who color their hair and want a cleanser that strengthens without stripping. The reviewer found the formula cleans deeply yet preserves moisture, leaving hair feeling thicker and healthier over several washes. Customers repeatedly mention improved texture and reduced breakage, so the single biggest reason to buy is its combination of cleansing and fortifying ingredients that support thicker-looking hair while maintaining vibrant color.

Key Features

• Scalp and hair thickening: Formulated to visibly thicken fine, light thinning hair by improving the look of density at the scalp and strands.
• Color safe cleansing: Cleans build-up and oil without stripping dye, helping to maintain vibrant color between salon visits.
• Gentle yet effective: Removes impurities and leaves hair feeling squeaky clean while preserving moisture so dryness and damage are not worsened.
• Nourishing actives: Includes ingredients like biotin and niacinamide to strengthen hair and support healthier texture over time.
• Pleasing scent and feel: Users report a fresh, pleasant smell and softer hair after use, improving manageability and styling results.

Who It's For

This shampoo is aimed at people with fine or naturally thin hair who use hair color and are concerned about breakage, texture and a loss of visual density. It works well for those who want a product that both cleanses thoroughly and supports thicker-looking hair without aggressive detergents that can fade color or dry the scalp.

It is less suitable for someone seeking heavy conditioning or a repair treatment for very damaged, chemically overprocessed hair; those users may need a richer mask or conditioner alongside this shampoo to restore extreme dryness or reconstruct hair fibers.

Pros & Cons

• Noticeable improvement in hair texture and perceived thickness for fine hair after regular use.
• Pleasant fresh scent and leaves hair feeling soft and manageable.
• Contains strengthening ingredients like biotin and niacinamide to support hair health.

Cons

• Not a substitute for a deep conditioning treatment; those with severely damaged or very dry hair may need additional moisturizing products.

Our Verdict
