Noticeable results since starting
[I received this product in exchange for my honest review] I loved using this kit. I have seen some positive results since starting it. My hair feels softer, fuller and generally better condition. It doesn’t smell really chemically which I was expecting. I plan on purchasing this again when it runs out.

Minty scent, slows hair thinning
[I received this product in exchange for my honest review] Been using Nioxin Scalp and Hair Thickening System 4 for Coloured, dry and damaged hair Treated Hair with Progressed Thinning, Trial Kit over the past few weeks, the shampoo and conditioner are actually green due to the minty scent it has which is quite overpowering and felt quite minty on my scalp. A little bit of shampoo goes a long way, it lathers up quite nicely. It comes with 3 steps the shampoo, followed by the conditioner and the leave in scalp and hair treatment which is easy to follow. I have been getting hair loss and it does seem to have slowed down since using but the minty scent and feeling on my scalp puts me off using it long term I'm afraid but happy to continue using it short term to help with my hair thinning.

Minty scent
[I received this product in exchange for my honest review] The scent of these is lovely! It's a minty smell and just wakes your senses! You definitely feel like your hair has been cleansed with the shampoo, and it does feel nice after the conditioner. The treatment is strange, having to massage it into your roots - I can't say if it has made a huge difference to my hairs' strength, but it doesn't strip the colour which is amazing!

I can really see a difference.
[I received this product in exchange for my honest review] This hairsystem has a really pleasant smell. The packaging is really nice with all the steps needed clearly printed on them. I've used this now for a few weeks and can see a real difference. I have quite thin hair, and it seems to be slightly thicker and feels really soft and clean.

Great shampoo
I remember my mum using this years ago and it had such a strong smell that was unpleasant. Well this one smells so much better, it’s still got quite a strong smell but is more minty than anything else. I haven’t been using it too long yet but my hair fall is definitely reduced since using it.

A refreshing surprise for my highlighted hair!
I’ve been using the Nioxin System 4 for just two weeks and I’m already noticing a real difference. I have highlighted hair that’s prone to dryness and breakage, but this system feels like it’s giving my hair new life. It feels stronger, there’s noticeably less breakage, and it stays hydrated without any heavy residue. The minty fragrance is refreshing and instantly uplifting, and unlike many shampoos I’ve used, this one doesn’t create any dandruff. I especially love the conditioner—it’s light in texture but works wonders when it comes to detangling and keeping my hair soft and manageable. The real game-changer for me has been the leave-in scalp treatment foam. It gives my scalp such a clean, fresh sensation—it’s like a cooling boost that makes my whole head feel revitalized. Huge thanks to Influenster for helping me discover this brand! I wasn’t expecting to like it this much, but now I’m genuinely excited to keep using it and see more long-term results.

Thickens your hair
Im 50/50 on the way this product works! It did really thicken my hair in a few washes, however it makes my hair still feel dry. The lather of the shampoo is really good and the conditioner goes a long way too. The scent is lovely with a minty fresh smell.
