This has totally saved my hair after a stressful year!! I started using this last summer after a recommendation from my hairdresser.
I can't live without this. I also use the shampoo from the kit, it looks like more volume, more hair and my hair feels fuller, I initially experienced that I was losing a bit of hair but it was explained to me that it helps to cleanse first from 'dirt' before you can grow stronger strands and now about 4 months later I've received compliments that my hair looks so healthy.
I love this - it really gives extra volume without a stiff product feel and keeps my hair fresh for 2 extra days. My absolute favorite, I can't live without it. People have asked if I have extensions because my hair looks so full, but I have to say that I also use the Nioxin kit 3 or 4 in the shower.
