Offering visible results in as little as 30 days, the Nioxin System 3 Scalp + Hair Thickening Treatment encourages fuller, thicker-looking hair with added body and shine.
Enriched with biotin and niacinamide, the serum lends non-oily moisture to the scalp and strands, helping to plump them and promote a more voluminous illusion. Biotin protects against breakage and noticeable brittleness, leaving the hair with a stronger feel over time, alongside a reduced appearance of split ends and dryness. Suitable for fine, fragile and colour-damaged lengths, use the serum daily in conjunction with the brand’s System 3 shampoo and conditioner for optimal results.

Strands of strength
[I received this product in exchange for my honest review] 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!

Serum filled with biotin and niacinamide for scalp health
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.

Does the job
[I received this product in exchange for my honest review] 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
[I received this product in exchange for my honest review] 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 and freshness
[I received this product in exchange for my honest review] 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 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.

[I received this product in exchange for my honest review] I felt much moisturized after applying Nioxin serum. The scent is nice. good packaging. Smooth and won’t leave my hands sticky. good value of money.

It works
Used this for a month now, my hairdresser checked my hair today and it has started to work. I find it best to apply by spraying on fingers and massaging in
