Great system.
[This review was collected as part of a promotion.] I started using the Nioxin System 4 bundle for my coloured, thinning hair and noticed a difference within weeks. The shampoo cleans gently without stripping colour, the conditioner leaves my scalp refreshed, and the serum adds a healthy fullness. My hair feels stronger, looks thicker, and has a lovely shine. It’s a salon-quality solution that really delivers on its promise to improve scalp health and encourage thicker-looking hair. Great smell. Big bottles to last too.

Foam hair treatment
[This review was collected as part of a promotion.] This product is a gem, after using the shampoo and conditioner, this final step of hair treatment really adds to the refreshed, clarified and healthy scalp and hair. It is an easy to use pump bottle with the product itself being a foam consistency rather than the usual oil or serum and is easy to massage into the scalp. Very impressed with the whole range.

Minty fresh mousse. Seems to work well on my scalp
[This review was collected as part of a promotion.] A minty fresh smell. Hair seems to look a bit thicker. Was amazed at the way this worked on my dandruff and kept my hair looking less greasy over a week. Worried I will use this up quicker than the shampoo.

Herbal scent and greasy
[This review was collected as part of a promotion.] Leave in treatment but I find it makes your hair very greasy so im not sure how we are meant to leave it in whilst also going agout our day. It has a herbal scent and it is very expensive. I have not noticed any difference in my hair

Game changer
[This review was collected as part of a promotion.] I’ve been using the Nioxin System 4 Hair Serum as part of the full System 4 routine, and it’s the perfect finishing step. The lightweight, foam-like texture makes it easy to apply without leaving my hair greasy or weighed down. It has that same refreshing minty scent as the shampoo and conditioner, which feels amazing on the scalp. I have blue hair, and just like the rest of the Nioxin range, this serum doesn’t strip or dull my colour. Instead, it leaves my hair feeling healthier and looking fuller. My scalp feels refreshed and nourished, and I’ve noticed much less breakage despite my constant bleaching. It’s quick to use, absorbs fast, and gives my hair that strong, resilient feel from root to tip. Definitely worth it if you’re looking for a treatment that actually supports hair health while keeping colour intact.

Recommend the whole set. Noticeable results
[This review was collected as part of a promotion.] I’ve been using the whole kit for over a month, 2–3 times a week as recommended. After cleansing my hair with the shampoo and hydrating with the conditioner, the final step is the serum. Usually, serums make my hair greasy and cause it to get oily faster. But I was pleasantly surprised—this serum is water-based and doesn’t weigh the hair down at all. It’s literally like applying water to the roots. At first, it seemed like it made no difference, but over time I started noticing that my hair looked thicker—and even a lot of new baby hairs started to grow.

Longer hair fresher hair
[This review was collected as part of a promotion.] Nioxin System 4 kit for about three weeks now and my hair feels stronger, softer, and noticeably fuller. The shampoo and conditioner leave my scalp feeling refreshed without dryness, and the treatment is lightweight but effective. My colored, damaged hair already looks healthier, and I’m excited to keep using it. Definitely worth it for anyone struggling with thinning hair! Great to use after washing hair I point the nozzle at my scalp and squeeze a little it to effected areas then massage then style my hair as desired dose not stiffen hair this way and I have seen a difference in my hair already my hair has grown

Great !
[This review was collected as part of a promotion.] I have been using this product along with the shampoo and scalp conditioner from the same line. This product is something completely new for me; it's a scalp serum that promotes healthy root growth and prevents hair loss, and at the same time, it's a styling product that lifts the hair from the roots like regular hair foam. It leaves hair at the root a bit sticky, but it gives you the volume that fine hair lacks. I do like using it when I'm styling my hair; it looks fuller.

Potent.
[This review was collected as part of a promotion.] I didn't like this set. I didn't like the smell. how heavy the packaging was. It wasn't effective as it left my hair greasy. not sure on ingredients. Wasn't great value for money for myself but would be for the right person.

Lightweight formula that works but leaves a crusty
[This review was collected as part of a promotion.] I have been using this scalp treatment for just over a month, every three days and feel it is a critical step in my haircare routine. I like that it is a lightweight formula, that is easy to dispense and apply. The product itself has a pleasant smell and melts into the scalp fast however my biggest concern is once it is dry it leaves the hair with a crusty texture, which is then hard to manage.

Good product if used correct
[This review was collected as part of a promotion.] I don’t believe I had used this product enough, as I’ve been spraying far too much and haven’t felt the benefit.i will continue to use and hopefully see the progression

Didn't like the scent
[This review was collected as part of a promotion.] I didn't like the scent it was too minty whereas I prefer a fruity scent. I cant say of it was effective as I couldn't use it due to the scent of the product.

Not much needed
[This review was collected as part of a promotion.] I really liked this serum and the smell is pleasant. Only a small amount is needed as it goes a long way. Made my feel really soft but I did find i had to wash my hair more often as it made it look greasy after a day.

Great serum
[This review was collected as part of a promotion.] This is a lovely serum, it is nice and lightweight with it being a foam so therefore doesn’t weigh the hair down. A little goes and long weigh and has left my hair looking much fuller and thinning areas starting to thicken out again.

Not for me
[This review was collected as part of a promotion.] This product is ok! The scent is nice and strong, however is quite uncomfortable when I use it! I have thick curly hair and it just doesn’t seem to help my curls! This doesn’t leave my hair feeling hydrated, and the foam seems to disappear quite quickly meaning I need to use more of the product
