NIOXIN System 2 Shampoo & Conditioner Prepack — 33.8 fl oz duo for natural/untreated hair with niacinamide & biotin, lightweight t

This prepack pairs a deep-cleansing Activ-Renewal shampoo with a lightweight Scalp Therapy conditioner to prepare hair and scalp for thicker-looking results. Clinically and dermatologically tested, the System 2 regimen removes buildup, balances moisture and reinforces hair structure to improve manageability and the appearance of density.

How does this kit improve the look of thinning hair?

System 2 targets the scalp environment and hair fiber to create the appearance of fuller, more resilient strands. The cleanser removes excess sebum and residues that can weigh hair down while the conditioner preserves moisture without adding heavy buildup.

• Activ-Renewal shampoo clears scalp oils, fatty acids and styling residue.
• Amp technology in the conditioner helps retain moisture and strengthen hair resilience.
• Formulation includes niacinamide and biotin to support healthy-looking hair texture.
• Lightweight finish leaves hair fuller without greasiness or stiffness.

What results can I expect and when?

Visible changes in hair density and fullness are reported by many users within weeks when the three-step routine is followed consistently. Results vary by individual, hair condition and styling habits.

• Studies cited improvements in perceived thickness, density and fullness for a majority of users.
• Fuller-looking hair often appears as buildup is removed and hair fibers gain improved body.
• Continued use supports ongoing scalp cleanliness and hair structure amplification.

How should I use the shampoo and conditioner for best effects?

Use the cleanser as the first step to thoroughly purify the scalp, then follow with the Scalp Therapy conditioner to hydrate and protect hair structure. Pumps are included for easy, controlled dispensing of the 33.8 fl oz bottles.

• Apply shampoo to wet hair, massage into scalp, then rinse and repeat if needed for a deep cleanse.
• Work conditioner through lengths and ends, leave for one to two minutes, then rinse for a lightweight finish.
• Use as part of a three-part Nioxin regimen for optimal cumulative benefits.
