It works. But you need to be patient and commited to it. I bought first just 2 for grey hair. I saw results but after like 3-4 weeks. But like i said i was very commited to it. Then i bought 4 pieces at once (cheaper for the delivery). Now im using it like 2 times per week and im happy about the result. i can recommand it easily

I’ve been using GR-7 for a while now and I’m extremely satisfied with the results. It works exactly as advertised, delivering noticeable improvements without any side effects. I was a bit skeptical at first, but after consistent use, I can confidently say that this product does what it promises.
This product has changed my look and my life. At first I wasn’t sure how it would affect my hair and what colour it would turn out.
I had been expecting a bit of colour but this has been life changing. It’s exactly as advertised and I would highly recommend it.
I thought I'd give this a go and am pleased to say that yes it absolutely works. I applied as directed for 21 days and now have my natural hair colour back instead of grey hair. Pretty amazing really!
This product really works. I am 56 and had some grey hairs, but they turned light brown like the rest of my hair. Blends it perfectly and looks absolutely natural. Been using it for two years now. Make sure you follow the usage instructions
Ten out of ten for this item, used once a week, I am 70 and would be a real grey if it wasn’t for GR7. But this is excellent the best I have tried. Been using it for 3 years now and would not use anything else.
I am very happy with GR-7. I am not quite done with the 21-day, once-a-day treatment, but my hair has quite a bit of color again. I had become completely gray due to aging. I'm 61 years old. My hair was originally blond, then gradually turned light brown over time, then finally gray. Now my hair is a combination of light brown with some red and golden, and of course some grays still. Some of the hard-core grays on the side of the head have turned kind of golden; you can tell they are grays with a hue, but just overall my hair looks so much better. I do not want to look dyed, so I like the mixed look GR-7 has given me. And yet, I think things are going to continue to change with GR-7. Another plus is that my scalp seems to be healthier as well. In particular, I had several of those stubborn so-called precancers (scabs) on my scalp; the kind that dermatologists like to cut or freeze out. I had already dealt them a pretty good blow using a combination of items I put on my head (vit C, castor oil, etc.). However, I noticed that the three that just would not completely go away, went away after about 2 weeks of applying GR-7 and massaging my scalp with it. That was a pretty nice unintended benefit! So, I will continue to use this. It's a little on the pricey side, but hey. There is the matter of the smell that some people complain about. It's really not bad at all. I made the mistake of telling my wife about a person I read about who quit using GR-7 due to his family complaining about the smell. I believe I predisposed my wife, and she gives me a hard time. To be honest, she would be giving me a hard time about something else, so it's built in. I believe, in part, she does not like her husband looking younger. And so it goes. My kids don't notice the smell at all, and they just roll their eyes when my wife complains. You can perceive a slight smell, nothing major, when you put it on, and for about 1 hour or so, but then the smell goes away once the hair dries. So, I recommend putting it on first thing in the AM. That way the smell will be gone, especially when yo go to sleep. Again, I am happy with this product. Very easy to apply, very good results.
I'm quite stunned at the sight of my hair... I can't believe it. Whatever it actually does, whether pigmentation or something deeper than that, it works. I have my greys covered I'd say by 70% after using it for 1 week. ONE WEEK. I'm taking the gr7 supplements as well because why not. Might as well do it right.
This is a great product, it has really helped reduce and remove the greys from the side of my head and in my beard. Easy to use, lasts for ages and helpful customer service team.
it is incredible. It did work very well, I have absolutely zero grey anymore. It took about a week and half to see first result and grey hair completely disappear after 3.5 weeks. I am astonished about these result, and my friend and familly too now!!
I use GR-7 No More Gray for over a year now and I find it the best product that easily, if used as adviced, gives back your hair colour, without affecting hair or skin health. I'm on the long run of using it and I truly recommend it!
I am a first time purchaser of GR7 and am on my 4th day of my applications. I indicated a 5 star but that’s yet to be seen. As for some of the unfavorable reviews, where indicated that this product contains toxins and or heavy metals. I take this very serious as I have 3 family members with Parkinson’s and Alzheimer’s/Dementia. If you can please send proof indicating this product contains the such or harmful in any way. As it’s indicated on their website the exact ingredients it contains. Which I looked up through an amazing app called Yuka. And it came up with an “excellent” rating. If anyone can assist with this it, it would be highly appreciated.
One question I do have to the folks at GR7. When is best to get a haircut at this point and when I do, will the hair grow darker not grey.
Thank you!!
