    Unbelievable product! Amazing!

    I live and work in the UK and my nails are thin, brittle and weak, always! I work in a specialist school and wash my hands and nails a hundred times a day. I went back to Norway to see my mum, she had recently purchased the kur Nail Hardener and I borrowed it. Amazing result!I have now purchased one for myself, my nails look instantly better, feel harder and I am so glad I got this product that does not contain any nasty additives. Highly recommended! Will be buying more, definitely!

    Didn’t make a difference

    My nails don’t feel any harder or stronger
