GR-7 AntiGrey 125 ml Repigmentation Shampoo - Hair Against Grey

No difference after 2 weeks of twice daily use. Will continue for another few weeks before giving up.

All 3 product was empty and the weight frompack was different:)

I've tried this product for 2 months, it worked for me but I can see why it has not caught on. It smells awful, and I had to use for 3 weeks before I saw results which admittedly were quite good. However I also use serum to straighten my hair, which does strip out colour, but thinking this was not a dye but some molecular miracle .. I straightened my hair, only the result was that it stripped my hair and brought back the grey. I have used 4 bottles so far and with longer hair it's gets all over your hair as it's just an open bottle with no precision to add it.An expensive experiment that I will not be continuing.However if you have very short hair and do not add any straightening or dyes and can afford it, it might work for you if you and others can bare the smell.
