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.

professional grade
[This review was collected as part of a promotion.] I don't often use products like this, but found it brilliant for my hair. You can tell the professional grade quality over buying something from the high street
