NIOXIN System 1 Shampoo & Conditioner Prepack — 33.8 fl oz Pumps, Light Thinning Care with Niacinamide & Biotin

NIOXIN System 1 is a three-part cleansing and conditioning regimen designed to strengthen natural, untreated hair with light thinning and improve the look of fullness and scalp clarity.

Built from over three decades of scalp and thinning-hair research, this prepack pairs the System 1 cleanser and Scalp Therapy conditioner in pump bottles sized for frequent use. The set targets scalp build-up and moisture balance to help hair appear denser, while lightweight conditioning restores resilience without weighing strands down. The formula features niacinamide and biotin alongside NIOXIN’s professional technologies to prepare hair for thicker-looking results when used as directed.

How does System 1 support a clearer scalp?

System 1’s Activ-Renewal technology focuses on removing sebum, fatty acids and styling residue that can collect on the scalp. A cleaner scalp surface creates a healthier-looking foundation for hair, improving the way strands sit and reflect light.

• Deep-cleansing shampoo removes excess oils and residue.
• Formulated to reduce pore-clogging build-up without over-drying.
• Prepares the scalp for follow-up thickening treatments in the regimen.

Will the conditioner leave fine hair heavy or flat?

The Scalp Therapy conditioner in System 1 is formulated to be lightweight while restoring moisture balance, so it strengthens without weighing hair down. AMP technology helps improve strand resilience and smooth cuticle layers for improved manageability and shine.

• Light-conditioning that detangles without added heaviness.
• Helps seal moisture at the strand level to reduce breakage.
• Maintains natural movement and volume after rinsing.

How soon can I expect to notice changes in hair appearance?

User studies show visible changes in fullness and thickness for many people within about 30 days when the three-part regimen is followed consistently. Results depend on individual hair condition and how regularly the system is applied.

• Clinically observed improvements in thickness and density among participants.
• Best results seen with complete, routine use of the full NIOXIN system.
• Consistency and correct application increase the likelihood of visible benefits.

What are the key ingredients and how do they help hair health?

The formula combines niacinamide and biotin with botanicals and antioxidants to support a healthy scalp environment and more resilient hair shafts. These ingredients are selected to complement the cleansing and AMP technologies, improving overall hair texture and appearance.

• Niacinamide helps support a balanced scalp environment.
• Biotin supports visible hair strength and structure.
• Botanical extracts and antioxidants nourish and protect the scalp surface.

Who is this for: NIOXIN System 1 is aimed at people with natural, untreated hair who are noticing light thinning and want a professional-strength cleanser and lightweight conditioner that promotes fuller-looking hair. It’s suited for daily or frequent use by anyone seeking to reduce surface scalp build-up, improve strand resilience, and create the appearance of thicker hair without heavy conditioners or styling waxes. If your hair is chemically treated, colored, or experiences moderate-to-severe thinning, consider a NIOXIN system tailored to those specific needs.
