Love
Love, helped with my hair loss and thickened my hair. I use the Nioxin shampoo, conditioner, mousse, and scalp care. Also, I take hair vitamins.

Get the complete set.. its amazing!
I purchased this product because after menopause I noticed I was losing a lot of hair when I would dry my hair after showering. My daughter had purchased the same product, except system #2, for my 75 year old mother just months before. I saw great results with my mothers hair growth and the end of her hair loss. I love the minty smell and the slight cooling tingling feeling I get while washing. Your hair feels very clean after shampooing. After I wash I apply the conditioner, which makes your hair very soft and healthy looking. I then spray on the Nioxin system 4 scalp spray and leave it on without rinsing. Love the continued tingle and cooling from the product. I then just stole as normal. I have noticed even after just a few washingseconds that the hair loss has lessened. I don't look like I have adopted a small black dog any longer (after drying my hair from hair loss) Ha ha I love this product and will continue to order it.

It works!
I’ve been having breakage and thinning hair over the last year. This product just in three months has helped my hair become stronger and a lot more volume!!!

Good Product but Cheap Container
It is a good product. I have been using it for years and still have a full head of hair. Partly genetics, I suspect, but the scalp treatment helps too Unfortunately, the last shipment arrived with the bottle cap broken (see photo). Nioxin has started using a flimsy, cheaper plastic to save a few pennies. For the price they charge I expect better packaging.

Effective product!
I use this mainly in my roots and my hair feels so much fuller. I am very impressed with the product. The smell is a little off. Can’t explain it, but I would buy this product again. My hairdresser even noticed a difference.

Hair really does grow, albeit slowly
I wasn't really sure if any of these hair growth products work or not. Given how expensive they are, it's not easy to just dive in. However, I figured if this works then it's worth the money. Just didn't want to see less and less hair on my head. The RESULT: After 3 months of daily use, I notice some very short hair on my head in some areas. Not sure if it was broken hair or new hair. After 4 months, I was convinced there was baby hair growing. After 6 months, definitely see improvement. After 8 months, definitely see more hair growing in more area of my head. So far so good. The CONS: The cost is relatively high.

This product is overpriced. In Australia for the same price you receive a set consisting of 150ml shampoo and 150ml conditioner plus 40ml of the hair thickener which is actually a mousse. The advertising on the Amazon site actually shows these 3 products in one image on the LHS of the main image. This image should not be there as it is misleading. So what do I now have? An overpriced mousse which you can pick up anywhere at a fraction of the cost.

Like this product, it really does work. Used it on the hair line at my temples as my hair is thinning, baby hairs sprouted and has since grown in well and lengthened. Now I don't look like I have a receding hair line when I put my hair in a ponytail. Huge bottle, will last a long time. Makes your hair feel stiff ,but I put it on at night and wash my hair in the morning. Be careful as not to let any run down your face as it will leave a red mark,but will be gone by morning, wash that off immediately. Best to use a head band to protect your face from drips running down.hold head back. Will buy again as it does work.

Llevo usando los productos de Nioxin 2 años y mi pelo es otro completamente. La única pega es que la espuma final puede escocer unos segundos, pero merece la pena.
