Good smell. Doesn't harm hair and the hair is really smooth and soft after use.

I dyed my hair blue and it becomes total grey after a single use of a purple shampoo. After using this product three times, my grey hair now has a little bit of blue in it again, only slightly though. Hard to see without light.

Not bad

Really easy to use! Fun to see the color changes. Beware about your hair color, if it’s yellow, you will get more green than blue!

Loved it

Best gray color! I discovered this product when visiting Tokyo and my hairdresser friend couldn't believe the results. I was very glad to find that it is available on Amazon for roughly the same price.
