Helps hair loss greatly
Helps to lessen hair loss great! Washing my hair I notice there is much less hair shed. Leaves hair very soft too.

Was having hair loss.
Until I started using this. Never ever suffered with hair loss. I have thick hair. I’ve been on medication and was loosing hair noticeably every time I washed. Started using this. And what a difference. No more strands in my hands each time I wash, will deffo buy more. This trial kit is a cheap enough intro to see if it suits you. I will be buying more in larger size .

Lasts a long time. Foam makes your hair stiff.
I love the shampoo and conditioner and for small bottles, they last a long time as you don't need to use a lot. Use a pea size amount of the shampoo and double cleanse the scalp. You won't get much lather on the first wash, but lots on the second. I have waist length hair (quite fine), so the conditioner didn't last as long as the shampoo even though you don't need as much as regular conditioner to make your hair feel soft. I wasn't as keen on the foam as it made my hair feel sticky/stiff (hence only 4 stars)

Great product
I recently had surgery and lost almost 50% of my hair which was very distressing. Having done a lot of research I purchased this system and started using religiously. Within 2 weeks I could see a difference as I now have much less hair loss on a daily basis. It smells lovely too. The only negative points are that it leaves your hair dry but I use a comb through conditioner on my damp hair which helps. The scalp treatment is sticky too but I put it on before bed and put a hair band over my head. It’s a little pricey but we’ll worth the results.

Do your research
Advised to use a teatree based product for severe thinning My scalp doesn't produce alot of oil meaning it doesn't need washing very often... first couple of washes left my hair feeling great, then a couple more washes in my hair was becoming more dry, fluffy and wispy! Because of the sheer volume created from the frizzyness it made it look I had less hair to begin with! You could see right through it, I'd say the same consistency as candy floss! Hopefully my partner has better results than I did

Nioxin 3-Part System
I tried the Nioxin 3-Part System (System 4) for coloured hair with more noticeable thinning. It’s a set with shampoo and scalp treatment aimed at making hair look thicker and healthier. It felt quite gentle and clean on my scalp, and my hair did seem a bit fuller after regular use, though nothing dramatic. At £25.17 it feels fairly reasonable for a specialist haircare kit. If you’ve got Amazon Prime, delivery is free and there’s a 30-day return option if it doesn’t suit you. Overall, decent but not a miracle fix.

You will definitely see results!
I brought the set of three, shampoo / conditioner / moose and now I just use the moose. Mainly because of cost but there is no doubt that this stuff works. I noticed the difference in the thickness of my hair and had baby hairs growing underneath, which I thought I was long past. I am a woman but always felt my hair was thinning a little near the front and after just a few washes I could start to see wispy new hair growth. I now use to thicken and add volume to my hair because it is so fine. I would say to use sparingly on the patches you want to focus on because it does cost quite a bit, but certainly to give it a go.

it does the job that I wanted
I was loosing my hair and was recommended this by my hairdresser after using for a couple of weeks the hairless stopped Then new hair started to grow even on the bald patch on the top of my head which had been there for over 30 years You only need to use a tiny drop each time you use it

Das Beste für meine Haare 👍
Schon beim waschen der Haare spürt man sofort das die Haare griffiger und voller sich anfühlen. Shampoo + Pflege + Behandlung empfehle ich all meinen Freunden weiter. Ich bin sehr froh das ich Nioxin - Haarshampoo gefunden habe 👍👍👍

Parola d'ordine :COSTANZA!
N4 adatto a capelli sottili colorati, uso questi prodotti da 7 anni, a causa di eccessive decolorazioni ero rimasta con capelli sottili fragili e pochissimi, dopo un anno di trattamento i miei capelli sono migliorati drasticamente! Prodotti super!
