Nioxin Scalp + Hair Thickening System 2 Cleanser Shampoo (33.8 fl oz) – The "Scalp First" Volume Solution

Nioxin System 2 Cleanser Shampoo is a specialized derma-purifying treatment designed for natural (non-color treated) hair that is experiencing progressed thinning (noticeable scalp visibility or significant hair loss). As the foundational step in the Nioxin 3-part system, this shampoo focuses on the "skin of the head," creating the optimal environment for hair to look and feel thicker. This 33.8 fl oz (1-liter) value size is perfect for consistent, long-term use, which is essential for seeing structural improvements in hair density.

Product Features
Activ-Renewal Technology: Uses a blend of peppermint oil and white tea extract to cleanse the scalp of sebum, fatty acids, and environmental residues that can clog follicles and stunt growth.

BioAmp Support: Contains cystine amino acids and lightweight conditioning agents that help increase the diameter of each hair strand, providing a "fuller" appearance from the first wash.

Derma-Purifying Action: Deeply cleanses the scalp surface without stripping natural moisture, ensuring the scalp feels refreshed and invigorated.

Value Size (33.8 fl oz): A professional-sized bottle equipped with a pump, offering several months of daily treatment at a more economical price point than smaller retail sizes.

Peppermint Scent: Provides a cooling, tingling sensation that stimulates blood flow to the scalp and leaves a clean, clinical fragrance.

Importance & Benefits
Reduces Breakage-Related Loss: By strengthening the hair shaft, it helps prevent the hair from snapping off, which is often a major contributor to the appearance of thinning.

Increases Hair Resilience: Fortifies the hair's cuticle, making it more resistant to heat styling and environmental stress.

Optimizes Growth Environment: Just as healthy soil grows healthy plants, a clean, stimulated scalp is the primary requirement for natural hair regrowth and health.

Instant Volume: Unlike traditional "moisturizing" shampoos that can weigh thin hair down, this formula is lightweight, leaving hair bouncy and significantly more voluminous.

Way of Usage
The "Double Wash" Method: Apply a small amount to wet hair. Massage gently into the scalp and hair for 1 minute. Rinse thoroughly. For those with high sebum (oily) levels, a second quick wash ensures the follicles are completely clear.

Focus on the Scalp: Remember that this is a Cleanser. Focus your massage on the scalp rather than just the ends of the hair to activate the peppermint stimulation.

System Synergy: For the best results, follow with Nioxin System 2 Scalp Therapy Revitalizing Conditioner and the Scalp & Hair Treatment. Using the full 3-part system is clinically proven to reduce hair fall due to breakage by up to 91%.

Consistent Frequency: Hair thickening treatments work best with consistent use. Use this as your primary daily shampoo rather than alternating it with other brands.

Safe for Natural Hair: This specific formula (System 2) is optimized for hair that has not been chemically bleached or colored.
