Leaves hair thicker and smoother.
[This review was collected as part of a promotion.] I have been using the Nioxin System 2 Hair Thickening Shampoo For Natural Hair with Progressed Thinning for around 6 weeks now, I wash my hair with it 3 or 4 times a week, I feel there is definitely a lot of improvement in my hair as I'm not noticing many bald spots anymore. The shampoo has a good lather to it and a lovely fresh peppermint smell. My hair is left feeling clean, healthier, stronger and thicker. I like to rub the shampoo into my hair for about 2-3 minutes before rinsing off. The bottle is a good size and the shampoo lasts a long time as you don't need to use a lot to get your hair clean.

A refreshing cleanse that adds visible body
[This review was collected as part of a promotion.] Cleans deeply and leaves hair feeling thicker and lighter at the roots. I noticed improved volume after required usage. It's effective but if you have eczema or scalp sensitivity, keep an eye on reactions.

Cleans hair well
[This review was collected as part of a promotion.] The shampoo produces a thick lather that thoroughly cleans hair while being easy to use and kind to the scalp. It effectively eliminates accumulation, including environmental pollutants and sebum that clogs follicles, leaving the scalp feeling renewed.

Great shampoo for thin hair!
[This review was collected as part of a promotion.] Nioxin Hair Thickening Shampoo is designed for those experiencing thinning hair, aiming to create a fuller, denser appearance. The shampoo gently cleanses the scalp and removes impurities, excess oil, and residue that can block hair follicles, which may help create a healthier environment for hair growth. It made my hair feel cleaner, lighter, and slightly more voluminous, particularly when used consistently alongside the full Nioxin system. Though, it is not a direct solution for hair regrowth.

No good!
[This review was collected as part of a promotion.] Really not good, I tried this for 30 days and it didn’t do anything unfortunately, I had such high hopes! On the plus side the scent was very pleasant!

Perfect results
[This review was collected as part of a promotion.] The huge bottles are absolute value for money, since using the product my hair has felt thicker and stronger only using twice a week. It does smell quite medicinal but does do what it says on the bottle. 100% feels like my hair is getting thicker by using.

Refreshing
[This review was collected as part of a promotion.] The product is very easy to use and the lid allows to distribute a small amount of product and not to waste it. The smell is nice and refreshing and the scalp feels clean after usage

Smells of luxury SPAs
[This review was collected as part of a promotion.] I’ve been very surprised with these products. Both the shampoo and the conditioner smells like the very expensive ones you can find in luxury Spas. The shampoo doesn’t do a lot of foam but it’s effective and leaves the scalp with a clean sensation. The conditioner is smooth too. The serum must be added at the end, with dump hairs. It’s sticky and smells differently but is very nice if applied to the ends.

Read this!
So, I bought this product at the start of the month because—plot twist—I’m 26 and my hair decided to start thinning like it’s trying to join a secret club. But nope, it’s not my genes throwing me under the bus; but rather a Dr. that prescribe me the wrong meds. My family’s hair game is strong and full—like, shampoo-commercial-level full. Honestly, my confidence took a bit of a nosedive (cue sad trombone), but here’s the good news: after just 3 weeks of using this magic potion, I’m seeing some seriously MASSIVE improvements. My hair’s looking healthier and thicker—like it’s hitting the gym or something. I’m pumped for the future, and I’m pretty sure my hair is too. Thanks for giving my scalp a second chance at glory!

Love it!
[This review was collected as part of a promotion.] Very great product! Since I began using this system my hair loss has slowed down considerably. When using the shampoo with the conditioner and the serum, it has certainly contributed to the health and thickness of my hair.

Great
[This review was collected as part of a promotion.] I love the texture and how easy it is to shampoo my hair with it. It cleanses so nicely and makes my hair so shiny and soft. It is a great size and really good as it lasts a while. Highly recommend if you have thin hair like me

Less hair loss but still some.
[This review was collected as part of a promotion.] I’ve been using this shampoo in combo with the conditioner and serum. The shampoo does a good job of cleaning my hair and smells nice. I’ve noticed less hair loss (still some but definitely less).

Amazing shampoo!
[This review was collected as part of a promotion.] I’ve been using this for a couple of weeks now. I must say wow what a difference. My hair isn’t as thin and is slowly getting thicker. Which has really boosted my confidence. I use it 3 times a week, you don’t need to much just enough to massage over the scalp, it rinses well and leaves your hair so soft with a lovely shine. I do use it as a system with the serum and conditioner these work well together. I highly recommend this and most definitely will buy more.

Lovely minty shampoo
[This review was collected as part of a promotion.] I felt the mint scent was very strong, I could still smell it in my hair 2 days later. It comes in quite plain packaging, but thats nice and simple. I think it is quite pricey for a shampoo, however I was delighted to receive this via Influenster. It did work on my hair. After 3 weeks, there was a visible difference.

Fantastic
[This review was collected as part of a promotion.] The product is very effective and easy to apply. It has a mild scent, washes well. It is packaged in a plastic bottle, with a smooth texture. It's good value for money. Washes so well with a small quantity. I am using this going forward as my hair didn't pull off

Fantastic shampoo
[This review was collected as part of a promotion.] I have always had very think strong hair, but I have suffered from low iron in my body, and i noticed significant thinning and change in texture of my hair. Since using these two products, I have been delighted that my hair appears to be thicker. I would definitely recommend it. I have also been using the serum to help the process. This is also a great product.

Worth a try!
[This review was collected as part of a promotion.] I’ve been using this shampoo for a few weeks now, and I appreciate how it gently cleanses without making my scalp feel tight or dry. It leaves my hair feeling fresh and manageable. While it didn’t give instant volume, over time I’ve noticed my strands feel thicker and healthier. A great choice if you’re dealing with thinning hair and want something gentle yet effective.
