Lives up to the hype
One of those products that, despite being expensive, is worth every penny. I was reluctant at first to wash without using conditioner but K18 makes the hair so silky, you don't even notice you haven't used conditioner.

I think it works
I think it works, but how can you really know? Ive used 3 bottles and my hair seems to grow without breaking as much but that may not be down to this product. Its easy to use though, however its very expensive
