Nioxin System 4 - Hair Thickening System For Damaged Hair with Progressed Thinning - Biotin & Niacinamide - Shampoo, Conditioner, Serum

I've given these products a full 2 months before I reviewed. Bottom line is they work.Before: my hair was coloured and long, started thinning after diet and surgery.( I'm an older lady) really dry and thin, tried everything all my usual conditioners nothing worked, I was wearing it up all the time as I could do nothing with it.After: first shampoo, condition and scalp treatment. Hair immediately felt soft and fed.. I only wash my hair twice a week but now it is longer thicker and in good condition, I can use straighteners again. No shedding and my hair is growing back around my hairline.Excellent products. Persevere to see good results 5 stars

My wife uses the complete nioxin system, as her hair grew back very thinly after some gruelling chemotherapy. The system works very well, with noticeable results. However, she seems to get through more of the conditioner, and this size represents very good value for money (rather than buying the whole system every time).

It is very good. It was left in the wrong place again ,, ,,,,,, It supposed to be left on my inside stair lift ,,, not at the door step as I’m disabled

Used this for 3 months and observed lesser hair loss / hair growth. The serum ran out very fast but the shampoo and conditioner lasted for 3+ months of alternate wash days.

Experienced hair loss for the last 10 years. Most recently due to perimenopause. Have tried absolutely everything on the market. I bought this on a whim about 5 months ago. My hair is the best it has been in years. I wash my hair once or twice a week, leaving the shampoo in for a good few minutes. Honestly, this is the best thing I've ever used for my hair, it is thicker, is growing quicker and looks a lot healthier generally.

Seems okay, not used for long.

Seems to suit my fine hair

Absolutely terrible! Has given me dandruff (which I have never suffered with). It has a horrible burning sensation and it is a horrible mint smell that is overwhelming. I would not recommend this product. Overpriced and has did nothing apart from burn my scalp.
