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.

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.

Smells Great, Cleans Well, and Hopeful for Hair Loss!
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.

Been using this for 20 years and it helps me keep what I have
I am balding and have been using Nioxin for about 20 years. It is not a miracle product, but it has helped me keep the hair I still have and keeps my scalp healthy. When I stop using it, I notice more shedding. The liter bottles last a long time and are a good value if you already know this works for you. This has been part of my routine for decades and I plan to keep using it.

You can FEEL IT working. Amazing shampoo for thinning and dry hair!
The shampoo and conditioner smells amazing. Works great. My hair was really dry from dye jobs. And I was getting concerned. This has helped my hair so much in the short time that I have used it. Seriously worth the price and you can almost feel it working. Amazing shampoo and I would 100 percent suggest this to anyone looking to improve hair health. The amount of shampoo/conditioner will last me quite some time as well!

Feels refreshing on your scalp
I purchased this back in February and have been using it religiously, about three times a week. I love the smell, and the lather. It makes your hair feel very clean. The conditioner is also very light weight and you dont need to use alot of it. Since most of us bought it due to, were losing hair more now than before. I can tell you that I have new hair growth underneath. (Picture, is kinda sloppy but that all new hair growth) . Im not getting any new hair on the top of my head. I used to have a lot of hair. Now I know ive lost more than half. It still looks ok. I just really had high hopes for this shampoo and conditioner. I probably will still buy it, because of all the pluses. I just wished it would grow more in my part.. Anyway, I do recommend it and I hope you have better results on top than I did..
