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 hair felt as though it was getting thin with age .tried this and I think it really worked . Lovely smell too .

Lovely shampoo and conditioner set. I've been using it for a few weeks now and I have noticed a decrease in the amount of hair loss

This was good but again it didn't last long enough to get the benefit out of it it's meant to make your hair thicker but as I said it doesn't last long you need to buy a bigger load

I have seen a massive improvement. I don’t know if it’s perimenopause or stress or just hard water or a combination of all of those, but since I moved to the UK I have had my hair falling out in clumps. It’s a huge relief to not leave a fur trail everywhere, and to visibly see the improvement. Who knew we’d reach an age where we’d just want to be more hairy?I’ve been using this for 3 months. It’s expensive-ish, but you only need a small amount at a time. The leave in treatment is also great, no oiliness or build-up. My daughter had started using it too, as she has really fine hair.

Seems okay, not used for long.

I’ve got from very thin hair to having re-growth all over. I use this everyday and have done for about 6 months. I have easily 10cm of growth and no hair fall. So happy! Great value for money and worth it.

Made my hair quite greasy but shampoo really cleans your hair
