GR-7 Professional Reviews 

This is a scam. It's just diluted hair dye. Smells like hair dye, irritated my scalp like hair dye. The clinical study they reference is of whether it is safe, not whether it works as they describe.

I did not test for heavy metals or other harmful chemicals however the product works very well. Almost all my greys are gone (back to my natural color) after about 6 weeks. I keep using it once a week and sometimes twice and it kept my natural color.

It actually worked! It's not the nicest process, but it did deliver results. I am curious about how healthy the ingredients are though and would have loved much more information.

Been using the product for around a week and maybe there has been some slight improvements in colour. That said, the formula smells toxic, so much that my partner doesn’t like me to go near her after I put it on. it has made me a little skeptical. I’m still going to continue and update this review accordingly.

What I don’t like is how murky this company is. Usually a health product would have the founder or at least a brand ambassador championing it. Someone who invented it maybe or research and medical approval. There is no about us page on the website. No person of credentials who came up with the formula and can explain to us why it is so good and how long they spent developing it. No one with skin in the game. Yet we are coughing up £50 and slapping it on our skin.

I looked up the parent company Mallhattan Ltd and it is owned by the Polish MAGNUSZEWSKA family, which you will find very little information about on Google. Maybe just a distributor.

If the company replies to this review, I would be interested in who developed the formula and why? Was there any health professionals involved and willing to put their name to it? Who are the people running the company now? Why not have an about page?

UPDATE

I have since been on the EU site where there is an about page and references to 15 years of development. I think my issues are possibly due to the UK distributor site and me thinking it was a UK company. Still some questions about who is behind it.

This product showed some improvements in hair however the company is dishonest in exactly what is exactly inside the product. The website is evasive and shady. No contact line and no uk office. Only a distributor company. Owner says tested by Eurofins. But no Eurofins document only a translated polish letter which is not safety nor a lab report. I asked consistently the ingredients. Long responses and lack of info. This resorted me to scientifically testing to sew if this product is safe my self with a heavy metal testing kit by Osumex. The results were shocking. Possibly has lead in it. Cadmium, cobalt and maybe even mercury but not certain. That is the worst carcinogenic things you can put on your scalp directly in to blood stream. This is a warning for potential buyers that this stuff is cancerous and toxic and will be reported to trading standards to remove from the uk completely. Thes people do not care. I have images of the test

It does work. Within 10 days I got visible results.

The only product I tested that really works! I will not remove all your white hair, but it will improve a lot.

I have brown hair and my white hair gets light brown with this product. I recommend it.

Anti-gray hair lotion GR-7 really works. My hair color was restored within 1 week. I use it 1-2 times a week now and it maintains the color. To be honest, I did not expect such an effect when I started using it. The only downside is that when you use this product, it reacts with metals and makes them darker. Therefore, each time during application you need to remove chains, jewelry, etc. Also, the bottle does not have an applicator. I bought a bottle with an applicator, which makes applying the lotion much easier. Additional advice - you should very carefully distribute the lotion over the hairs. Otherwise, it may dry out on your scalp and leave dry patches.

It truly did what it said! Worked well for me

Products work as advertised. Been using anti grey treatment for 45 days and most of my hair has turned black. Very happy with product. Will continue using.

I bought 3 bottles each of the grey hair treatment and shampoo. After 2 weeks, my grey hair became not quite my natural brown (a reddish tint) leaving grey at my temples and forehead. When I got my hair cut, my hair was back to grey so it doesn't seem to produce the claim that it turns your hair color at the roots. Also, I had to stop using it (my wife made me) because we noticed that much of my hair was falling out which is not usually the case. Seems like an expensive Grecian Formula Hair Color product.

Works! For now...

Hi all,

I am writing this review in order to save more people from buying this product. I think that this is a complete scam. I have bought it after I saw the video from Bryan Johnson grey hair reversal success video. I have tried it for several days. It has caused a severe irritation to my scalp, the smell is awful like it contains chemicals that could be harmful for the health. After the third day and having a severe scalp irritation I have stopped using it.

Then I have decided to search for more stories related to GR-7 and it seems that according to the dermatologists it does not contain anything that can potentially lead to reversing grey hair.
There is a review from dr Dray on Youtube and she is explaining in details why Gr-7 cannot work. (The video review is called Bryan Johnson's GRAY HAIR REVERSAL SUCCESS)

Do your thorough research before buying anything and do not be fooled by the positive reviews as they might be fake.

This product doesn’t work and customer service only ignore the emails.
After using the product following the instructions to the letter, the product didn’t work.
The indications said that you should see results after 7 days so I thought let’s give it time but after 1 month and 2 anti-grey bottles, I give up. I contacted customer service but they didn’t even bother answering my emails. I have to say that I use the shampoo too and this is a good product but the point is that the anti-grey lotion didn’t work.
Since the product is very expensive, I expected a better customer service but I was wrong. All in all, a big disappointment and I won’t buy GR7 products anymore.
If this help to anyone who wants to buy the product, my hair is dark (used to be), long and a bit greasy.

My hair had greying/going white from the temples, down to behind the ears. This product has reversed it entirely! I didn’t wash my hair for several weeks, but did rinse in shower due to sweat caused by exercise.

It’s had a continued positive effect, generally lightening my brown hair, giving it more sheen. A female friend even asked if I dyed my hair because it looked so good (she swore it was meant in a good way haha).

Anyways, have had great success and plan to continue maintenance use!

Good product, but will not get hair 100% dark.
It will hide some grey, but will look faded.
I followed the directions to a T , and I'm still trying to get to 100% with what I have left after a month of use.
I wish it would work better, because it's simple to use. Just not sure if it will or not

I doesn't work on me after 20 days. I washed it probalbly few more times than suggested. But after almost 3 weed the white hair are exactely like the first day, so I'll stop.

Still can't believe it!
I used it religiously the first 7 days, twice a day. Its a miracle. The only struggle is the bottle, you need to be really careful as you apply the product to the roots, as the bottle is not ergonomic.
Couple of weeks after the miraculous results, i had to use it twice a week but i couldn't make it due to some health reasons. Some of the hair that i regained the original colour gone grey again, but not all of it. Now i will go back to regaining process and i will use it twice a day to regain all again. Now i understand how important it is to continue using the product to maintain the original colour. (*used 2 bottles by now, 1st bottle finished as i regained my original colour)
Please come back with a better packaging and a bottle that can be used easily.
I recommended this product everyone around me!

I found this product from a Youtube video by Bryan Johnson on gray hair. My mom has jet black hair, but finally started to grow some grays.

Pros:
- Fast Shipping. I live in the USA and it shipped from their Poland warehouse fairly fast.
- Instructions are clear. Do not wet your hair for first 7 days, and continue with regular routine after. This was the hardest part for someone who is used to washing at least 2x/week or every other day.
- So far, the grays have started to reverse on her head! I was pleasantly surprised at how effective it is.

Cons:
- The formula has an odd almost vinegar smell, so you would need to maybe mask it with something else like leave-in-conditioner at the tips of your hair
- BOTTLE DESIGN. (This is the reason for the 4-stars insteads of 5). The product spills quite a bit due to the bottle not having some sort of nozzle or application to put directly onto the scalp as required, which results in losing a lot of liquid when you try to use it. For the cost of the product, I think the company should invest in better bottle applicators so customers benefit from the entire product without losing liquid volume.

Overall: would recommend to give it a try. I bought four (4) bottles and looking forward to seeing how my mom's hair turns out once she's done with all of them :)
