Review: a lifelong staple – cleanses, stimulates, and delivers results for overprocessed hair - I’ve been using Nioxin System 4 for years, and despite trying numerous other shampoos and conditioners, it remains a constant fixture in my shower routine. While I don’t use it daily, as overuse can be drying and slightly color-stripping, once a week, it’s exactly what overprocessed, thinning, or fragile hair needs to reset and thrive. Performance: System 4 is meticulously designed for chemically treated, noticeably thinning hair, and it delivers on its promise. It deeply cleanses the scalp, enhances circulation, and effectively removes buildup that clogs follicles. My hair and scalp always feel balanced, invigorated, and lighter after use. The shampoo and conditioner have a smooth and creamy texture, neither runny nor heavy. Over time, I’ve noticed a noticeable improvement in hair density and scalp comfort. Fragrance & Feel: The scent is fresh, clean, and slightly minty, with a salon-quality fragrance that’s pleasant and not overpowering. There’s a pleasant cooling sensation on the scalp, which enhances the effectiveness of the product. Packaging Details: I ordered the liter duo, and they arrived perfectly sealed, with two different colored pumps. This thoughtful detail is especially helpful when you’re washing your hair with eyes full of soap. Although it may seem small, not having to guess which bottle is which is a significant advantage. Having the pumps included, without having to beg for them in-store, is a big win. Everything was wrapped securely, ensuring no leaking or issues. Value: While prices have increased, this set still offers excellent value for the quality and quantity of products you receive. It provides true salon-grade scalp and hair therapy in large bottles that last for months. It’s not a trendy product; it’s a professional staple with a proven track record. Key Ingredients (System 4): • Peppermint Oil: Cooling and stimulating circulation. • White Tea Extract: Antioxidant support. • Nettle Root Extract: Soothing scalp. • Niacinamide & Biotin: Supporting hair strength. • Sodium Laureth Sulfate: Deep cleansing agent. • Menthol: Giving that signature tingle. Nioxin System 4 is a trusted, proven, and effective hair care product that delivers results every time. Whether you’re recovering from damage, breakage, or just need a weekly detox, this set is the product you keep around when your hair needs to get back on track.
Review: Wonderful product! - I love this shampoo and conditioner. I think it has helped immensely with stopping my hair from thinning and I love the smell and the way it makes my scalp tingle. I will definitely be ordering this again when the time comes.

### ⭐⭐⭐⭐⭐ Wonderful product!
*by L***. on December 30, 2025*

### ⭐⭐⭐⭐⭐ Smells Great, Cleans Well, and Hopeful for Hair Loss!
*by S***I on August 10, 2025*

I've been using the Nioxin Shampoo and Conditioner for about a month or two now and am very happy with it so far. While I can't speak to its effectiveness for hair loss yet—as my research suggests it can take six months to a year to see results—I'm thoroughly impressed with its other qualities. The shampoo and conditioner have a great, refreshing scent and do an excellent job of cleaning my hair and scalp. After each wash, my hair looks and feels fantastic. I'm hopeful that over time I'll see some improvement in hair loss, but for now, I can confidently recommend this product for its cleaning power and great results. If you are specifically looking for a product to help with hair loss, I would suggest doing your own research and being patient with the process.
