Nioxin System 1 Shampoo

Product Overview

• Designed for: Natural, untreated hair with light thinning. That means hair that has not been heavily chemically processed (no heavy bleaching / perming / relaxing) and where thinning is mild / early stage. 
• Purpose: To gently cleanse the scalp, remove build‑up and excess sebum, reduce follicle‑clogging, and help hair look thicker / fuller over time. It's step 1 in Nioxin’s three‑step System 1 kit (Shampoo → Conditioner → Leave‑in Treatment). 

Key Features & Benefits

FeatureWhat It Does / Why It MattersWild mint oil (Mentha arvensis leaf oil) & peppermint oilThese give a refreshing / cooling sensation on the scalp; help stimulate scalp circulation; help regulate oil/sebum production. Salicylic acidHelps exfoliate the scalp, removing dead skin cells, clogged pores, product residues or buildup. This helps create a cleaner scalp environment, which can support healthier hair growth or reduce follicle obstruction. Niacinamide, Biotin, Panthenol, antioxidant extractsThese help strengthen hair strands, offer nourishment, reduce breakage and support hair resilience. Lathers well, cleanses deeplyBecause of surfactants (SLS / SLES etc.), it’s effective at removing oils and buildup. Good for people who feel their scalp often gets greasy or hair flat. Visible fuller look promiseAccording to Nioxin, using the full System 1 (including this shampoo) regularly gives visible improvements in hair fullness, thickness appearance, and reduced breakage. 

Specifications

Strengths & Where It Excels

• Very good deep cleaning of scalp; helps remove oils, product residue, environmental pollutants.
• Gives a refreshing, cooling and invigorating feel (thanks to wild mint / peppermint). This can help people who dislike heavy greasy feel or smell.
• Supports hair structure via strengthening agents; helps reduce breakage.
• Good for light thinning / early density loss; helps “bulking up” the existing strands so hair looks fuller.

Things to Be Mindful Of / Limitations

• Because it contains strong surfactants (SLS / SLES etc.), it may dry out hair, especially mid‑lengths and ends, if your hair is already dry, curly or chemically treated. Might need extra moisturizing conditioners or treatments. 
• Menthol, salicylic acid, essential oils: some people may find scalp tingling or irritation. If you have sensitive scalp, patch‑test or use less frequently.
• It is not a colour‑safe formula (System 1 is for untreated hair). If hair is coloured or chemically processed, other Nioxin kits (System 2‑6) might be more appropriate. 
• Visible results take time. Don’t expect dramatic changes overnight—consistency over weeks is important.

Why Choose This Product?

You might pick Nioxin System 1 Shampoo if:

• You have natural / untreated hair and are noticing that your hair seems thinner, flatter, or less dense than before.
• You want a cleanser that not only cleans but also supports scalp health and strengthens hair.
• You don’t mind a stronger cleansing sensation (cooling, possibly tingling) and are okay pairing with a good conditioner to offset dryness.
• You want to use a full system rather than just a standalone shampoo (because the System 1 Treatment & Conditioner boost the effects).
