Purchased, used but no visible changes

This product surpassed my expectations, fine product made in Japan worth every dollar awesome scent and delivers beautiful results. Lots of suds and delicate feel after each use…Would definitely keep using and buying….Well recommend!!!!!!

My hair has more gray underneath then on top so overall i dont look too gray yet, but i did notice that my hair did look darker after a few applications. And unlike other similar type shampoos that normally start changing to an almost reddish foam after leaving on hair for like 5 minutes, this one stayed white although the shampoo itself was a dark color, it rinses with white foam. Overall going to keep using this and will report in if its not that great but as a subtle hair color change its perfect for me so far. This is for darker brown or black hair.

This product is not bad as a shampoo, but useless for so called "gray hair reversal". So being just a regular shampoo it could cost less and have better smell

I’ve been using this duo for about 3 months now and the difference is noticeable! My gray hairs have significantly faded and my hair feels and looks healthier and stronger. The smell is also amazing. Highly recommend!

Hearing lots of good about this product. Love the smell and cooling, unfortunately, not for me...felt itchy after washing.
