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. Great scent and great size for the price.

Impressed!
[This review was collected as part of a promotion.] I am amazed by this product. The bottle is huge and definitely lives up to its promises. It has a peppermint smell, which makes your hair and scalp feel clarified and refreshed. The shampoo does not dry out your hair like a lot of others out there and combined with the other two products from the range, I have noticed a difference in how my hair looks and feels, and it is 100% fuller and stronger.

Minty fresh shampoo that works really well for dan
[This review was collected as part of a promotion.] A minty fresh smell that you only need around a 10p piece to wash your hair, my hair is long. 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.

Drying
[This review was collected as part of a promotion.] It has a very herbal scent which can be quite overpowering but I do find it very dry on the scalp. Its quite hard to wash thoroughly and I dont find it very nourishing. I cant say I have seen any hair growth or any prevention sadly. And it is very expensive

Game changer
[This review was collected as part of a promotion.] I’ve been using the Nioxin System 4 Hair Thickening Shampoo and I’m so impressed with the results. Just like the conditioner, a little goes a long way — even with my long, constantly bleached hair, I barely need any to get a rich, refreshing lather. It smells like mint, which makes every wash feel like a spa moment for my scalp.
I have blue hair, and this shampoo doesn’t strip the colour at all, which is a huge win. My hair feels healthier and cleaner, and I’ve noticed it stays less greasy between washes. It’s also really helped with breakage — my bleached strands feel stronger and more protected after every use.
It’s definitely worth the money. I’ve been using it regularly and still haven’t even used up a quarter of the bottle. For me, this has become a must-have in my hair care routine.

Works with consistency
[This review was collected as part of a promotion.] This product is good for thinning hair. You do need to be consistent and give it a good few weeks to start to notice the difference. Smells nice and packaged well.
