Amazing
[This review was collected as part of a promotion.] The Nioxin Thickening Treatment from System 3 has honestly been a standout in my hair routine. It’s a leave-in scalp treatment designed to boost the appearance of thickness—and it really works!
The spray is lightweight, non-greasy, and super easy to apply. Just a few pumps onto damp hair and scalp, and it starts working right away. It gives this refreshing, tingly sensation (thanks to the peppermint/menthol), which feels like it's really waking up your scalp and stimulating growth.
Over time, I’ve noticed my hair looking fuller, bouncier, and healthier—especially at the roots. It doesn’t weigh hair down or leave any sticky residue either, which is a big bonus if you style your hair afterward.
✅ Pros:
Instantly makes hair feel and look thicker
Cooling, stimulating effect on the scalp
Lightweight and easy to use
Great for coloured or chemically-treated hair
Part of a system, but also works well on its own
❌ Cons:
The menthol feeling might be intense for sensitive scalps
Works best when used consistently
Overall, the Nioxin Thickening Treatment is a must-have if you’re dealing with thinning or flat hair. It adds volume, supports scalp health, and helps bring back that fresh, fuller feeling—without harsh ingredients. 💆♀️✨

Strands of Strength
[This review was collected as part of a promotion.] Really impressed with this serum so far. It’s easy to apply and doesn’t leave any greasiness or residue on my scalp. The scent is fresh, and I’ve started to notice my hair feels stronger and less stretchy when wet. Hoping for even better results over time, but so far, it’s looking promising!

Lovely minty fresh scent.
[This review was collected as part of a promotion.] I was lucky enough to be asked to test this and I loved the benefits of using it! Light weight feel which seemed to give my hair some much needed moisture. Stuttle minty smell which was pleasant for a hair product. The 100ml bottle is just over the size of a standard coffee mug which is ample for around 2 months use as you only need 3 pumps. I would recommend the Serum.

Serum containing biotin and niacinamide, moisturis
[This review was collected as part of a promotion.] Routinely I apply around 10 pumps of this all over my scalp, particularly aiming for my thinning areas such as my crown and temples. It's been excellent at adding volume to my hair immediately for a quick fullness but also I have noticed slight more baby hair volume coming around my temples! It has many active ingredients in it which promote scalp circulation such as wild mint oil, caffeine to help stimulate hair follicles and vitamin B3 which nourishes the roots to encourage growth. The packaging and bottle is very simple and efficient, with a pump to minimise product waste and a safety clip in to prevent spillage.

Effective Serum
[This review was collected as part of a promotion.] The serum comes a 100ml bottle, with a nozzle which serves as an easy applicator. The scent is not too strong, and the ingredients include biotin and niacinamide. It’s a once daily application, and is a leave in serum. Works effectively.

So impressed with this hair set
[This review was collected as part of a promotion.] I have been using this set on my hair, the shampoo, condition and hair treatment and my hair has never felt so soft and looked so shinny (in a healthy way not in a greasy way) after postpartum my hair lost its life quite literally but glad to have found products that worked for my hair. You also get lots of product so it’s great value for money as it lasts ages and I have long hair so normally use a lot of product.

A powerful, tingly scalp booster that adds volume
[This review was collected as part of a promotion.] Nioxin Scalp Treatment Review 🌬️💆♀️✨
Okayyy, so after braving the Nioxin shampoo and conditioner (aka the minty ice storm ❄️), I finished the trio with their Scalp + Hair Treatment — and let me just say: this little bottle packs a punch.
It comes with a nozzle applicator, which I loved — super easy to direct right onto your scalp without making a mess. Just a few sprays and... BOOM! That signature Nioxin tingle hits again. Yep, it’s still got that “just dunked my head in mouthwash” feeling 😅 but I was already used to it by now.
And listen — this treatment is like a wake-up call for your scalp. It’s cooling, refreshing, and absorbs quickly without leaving any weird greasy residue. My scalp felt energized (if that’s even a thing?), and my roots definitely looked fuller after a few uses. It gives a bit of volume at the crown and helps with that freshly washed feeling lasting longer.
Bonus: you still smell minty-fresh like a walking breath mint. 🧊✨
💙 Final Thoughts:
✅ Easy to apply with targeted nozzle
✅ Refreshes, cools, and adds volume
✅ Great finishing touch to the full system
🚫 Still not ideal for sensitive skin — that tingle is real!
If you’re committed to the Nioxin system, don’t skip this step — it ties it all together and really elevates the results. Just know it’s not for the scalp-shy 😉

Effective
[This review was collected as part of a promotion.] This is the treatment part of the system. Still same minty scent. Now this made my scalp tingle for about 15seconds before settling down.
I am not certain if this was supposed to happen. Did not burn or anything like that. Just the mild tingling.
All combined, my hair was clean, moisturised and made styling easy. Noticed no damage to my coloured hair at all. Rather my coloured hair shone bright after the wash and treatment.
Not used this enough to comment on effects of my hair thinning but the damage seems to be much better after a few uses.
