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 Feature What It Does / Why It Matters Wild mint oil (Mentha arvensis leaf oil) & peppermint oil These give a refreshing / cooling sensation on the scalp; help stimulate scalp circulation; help regulate oil/sebum production. Salicylic acid Helps 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 extracts These help strengthen hair strands, offer nourishment, reduce breakage and support hair resilience. Lathers well, cleanses deeply Because 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 promise According to Nioxin, using the full System 1 (including this shampoo) regularly gives visible improvements in hair fullness, thickness appearance, and reduced breakage. Specifications Spec Detail Typical size ~ 300 ml bottle is common; also larger (salon‑size) packs available. Texture Gel / cleanser gel; minty, cooling texture; lathers into foam. Ingredients to note Surfactants like Sodium Laureth Sulfate & Sodium Lauryl Sulfate; Mentha arvensis, Mentha piperita; Salicylic acid; also botanical extracts (nettle, hops, etc.), antioxidants; fragrance. Skin / scalp compatibility Clinically / dermatologically tested; made for scalp cleansing and sensitivity though because of active ingredients (salicylic acid, menthol), might be stimulating. Best for scalp that tolerates those. 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).
