System 1 Cleanser - 1000 ml

Great size of bottle for the price: I paid more for this at the hairdresser for a smaller bottle. My hair definitely feels thicker after using it, I only wash my hair 2-3 days to get the most out of it. I use this shampoo on recommendation of my hairdresser as I have very thin and fine hair and I have an oily scalp (for those with similar issues I was discouraged from using conditioner and heat styling accessories at every wash, just every so often to help with the fine limp hair). I try and wash my hair as little as possible to 're-train' my scalp, but it definitely feels thicker, its lovely and clean when washed (I'm talking genuinely squeeky clean) and have a lovely minty smell. Recommend the big bottle you get more for your money.

Excellent quality

I am always very wary when it comes to products like these and I never buy any products that make this claim to give you thicker hair or to even regrow hair, but this is just amazing! I did a lot of research before buying this product and everywhere and everyone who has tried it says the same. From the first use my hair and scalp felt a lot cleaner and my hair didn't feel like it was flying off in the wind like it normally did. After about six months of use, maybe a little less I could see a definite regrowth along my hairline and then within the rest of my hair. I will never change to another shampoo again! Just make sure you really work the shampoo in, tilt your head upside down even when shampooing to really get the blood flow to your head. Simply amazing!!

Good value considering it’s size and how long it lasts. The only issue is knowing how effective it is, it is part of a 3 step system. Shampoo, conditioner and a spray. As a man with thinning hair, I dare not stop using it in case I lose more hair. A catch 22! So it is hard to tell how effective the product is.

Best shampoo for thin hair, I don’t think I’m loosing my hair but it has always been thin. Using this alongside rosemary oil and I now often get comments about how thick my hair is

I have been using this shampoo for years now & I wouldn't switch to anything else. My hair has been shinier, less greasy & better quality than with any other shampoo. If you get a shampoo pump for the large bottle, it's even easier to use than a small bottle.

Haven’t noticed much hair growth but my hair is definitely thicker. Have been using this product for about six months now. The shampoo also lasts a very long time as you only need a tiny amount.

This is the best I have ever used

This product is amazing for those with baby fine hair or who seem to lose hair based off stress levels. It has done wonders for my hair by stimulating the baby hairs into growing. I definitely recommend this product when anyone is looking. Even my hair dresser was surprised at the wonders that nioxin has done for my hair. Love it!

El producto realmente funciona, hay que tener paciencia como en todo pero gracias a el se me ha dejado de caer el cabello, lo recomiendo ampliamente y comprarlo por amazon sale mucho más accesible que en cualquier estética.

Buenos precios, buenos productos.

Eccellente come sempre!! I prodotti nioxin sono sempre stati i migliori, peccato che hanno cambiato negli anni delle formule e non sono più uguali a prima. Ma comunque sempre molto validi!!

Ottimo shampoo, scoperto dal parrucchiere e acquistato qui su Amazon a un prezzo ultra conveniente! Ha risolto i miei problemi di forfora, rende i capelli morbidi, profumati e brillanti.
