Rubbish.....it doesn't work, still got grey hair even after months of using it and spending lots of money !
Top marks, Im not looking back.
I tried GR-7 with some scepticism, so was delighted to find my pepper and salt hair has returned to its original shade within three weeks. On visiting my hairdresser she was absolutely amazed to see the change. It is working out to be quite economical, as there is plenty left for maintenance treatments to retain my colour. I will definitely order again when it eventually runs out.

Działa , tylko trzeba wytrwałości . Na początku włosy są żółte ale z czasem zmieniają kolor na właściwy .
Very bad, after 2 months the product did not arrive. I even paid customs. In the other hand, my friend bought the product and did not work. In summary, I have seriou doubts and concerns about logistics and efficacy
I've been using this product over the 3 weeks and it just doesn't work. I still have the grey hair and my scalp is more dry now than before. Be careful with this product 😞
I've been using this for about a month now and I can say it does work. I have had a lot of grey hair over the years primarily due to stress, but since using it, they've become less obvious. I'm hoping that with time and frequent application, GR-7 completely restores my hair back to normal. But from my short experience, I'd recommend it.
I am very happy, it works, at the beginning I had some hair left on my hands, but the gray hair is gone, and I must say that I was smoking cigarettes and drinking strong coffee normally. I wish I had taken pictures of my hair before and now after 21 days, and I used GR7 once a day and washed my head every 4-5 days. I recommend it, it worked for me. My natural color come back 😉
I would deffinatly recommend gr7 to anyone who has grey hair.I have been using this product now since the beginning of lock down and it certainly has got rid of my silver/grey roots.I now have my natural medium brown shade back.Im very impressed and will continue to use.It saves me lots of money going to the hairdressers to gave my hair coloured.Big thanks to gr7
Satisfied with this preparation, it works. Hair regains its color. I didn't have any side effects while using it
After some 4 days , hair started to turn yellowish, which scared me a bit, but that was the sign of change. Now hair is back to normal colour - 95%.
Quick delivery. Great product. It works but takes a bit of effort for the first few weeks. Once it is working its simple to use and much better for my hair than hair dye.
This does absolutely work yes.Its not an overnight fix,so if you want that,forget this and buy some Just For Men or similar. I used it twice a day for three weeks,which was,for me,one bottle.It gives you your own natural colour back,but as iv said,you have to be consistent and patient.It does what it says on the tin!
It hasn’t worked for me yet and Iv used it for 8 days now but can see a bit off progress just waiting for results, since this review above I’m starting to see results
