GR-7 Professional Reviews 

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

Ordered a pack of 4 GR-7 bottles, package arrived open and 1 bottle was missing.

Avoid the UK vendor, go to the EU site.
Expect you will not receive the full order.

Honestly not what I hoped for. I switched to mayraki products because they are more natural and actually work.

I have been using GR-7for almost a month. All my grey gone but, still have yellow/redish hear. Hoping this will go in next few weeks.

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.

Great product

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.

Gr7 works great. I don’t know exactly how it does it but most of my grays are returning to their original color it’s crazy.

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!!

The product seems to have some minimal impact on grey hair. Stopped coloring hair when starting using GR-7 and now my hair is mostly grey. It could be worse though without using the product.

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!

Have used it for 3 days, will be using it for a month to observe the complete results

AVOID - I returned an unused product and they didn't refund me since it was received by them, now ignoring all my emails. Order 269106

This is the second review after more than one year of use. In my case the product does work although the color varies across the hair and my hair is blonder than before. I only use the product two times a week or less. For me It is far better than coloring and the hair looks natural, healthier and shinier. My hairdresser is amazed by the result.

After experiencing with myself and reading
gR7 directions I recommend everyone under treatment doing the following:

1. Do not use hair products with silicone in your scalp when you are under GR7 treatment because these products are preventing the GR7 product to be absorbed. Read the composition of your shampoo and any other hair conditioner and get rid of
all the siliconed hair products.
2. Use a syringe to apply GR7, say one very thin for example content 1 ml. Shake well the GR7 bottle and fill 2/3 of the cap. Then charge the syringe (without the spike of course) carefully with the fluid and distribute it into the scalp. Try Not to put the liquid into the hair because it is a waste. Direct the fluid to the scalp slowly like painting small dots across your head. Massage the scalp to cover all the head. Charge the 1 ml syringe three times. You will be using 3 ml in total which is enough quantity for one use. You wouldn’t be wasting the product at all.
3. When you apply the product do not wash or wet your hair for, at least, 12 hours to allow the product to work properly.
4. Do not apply the product on wet hair because it will not work properly. Your
Hair has to be dry and clean.
5. Clean carefully your hands before and after using GR7 and do not let product into your eyes because it is very strong and stingy, be thorough and careful.

I hope to help everybody with my experience.

If you also got scammed by this Polish company that poses to operate in the UK, this is how you get a refund:-
Send this to your financial services provider (PayPal, bank etc):-
‘The product is not as described. They say it 'it gradually restores natural hair color from the roots, as new hair grows in'. And they said it can take up to 21 days to see results. I used the product for 2 months and had no results whatsoever. All of the interactions with the company, and also the information on the website indicate that the product will work if you follow the directions. I followed the directions very carefully and nothing happened. There is no mention that the product doesn't work with some people, just assurance that it will work.‘
If you paid with PayPal, start with them. If PayPal deny your case, try your bank.

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!!

My hair looks amazing. Original color - nothing fake looking. I’m very happy with the results.

The product works but don't pay for express shipping. This part is a lie. I ordered mine on Dec 3 with express shipping and I'm still waiting. I've sent 2 emails and have had no responses.
