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!!
Prodotto dall’odore nauseabondo che mi ha irritato il cuoio capelluto. Avendo nel frattempo ordinato un secondo flacone ne richiedo il rimborso e vengo accusata dall’limpiegata” di turno di dichiarare il falso poiché il flacone non mi sarebbe nemmeno ancora arrivato e bastava dire che ho cambiato idea. Dai loro migliaia di test in un laboratorio “indipendente”non risultano alcune reazioni segnalate. Sapesse quanto me ne importa….,
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!!
sentite io non sono scettico ma di più quando vedo queste pubblicità,e come sempre ho voluto spendere altri soldi per vedere....... e VI dico che è davvero MIRACOLOSO!! ancora non ci credo e non so che tipo di prodotto chimico potrebbe essere, ma vi dico che su di me ha funzionato di bello!!! t tutti pensano che mi tingo i capelli ma sono naturali senza crescita bianca....
My hair looks amazing. Original color - nothing fake looking. I’m very happy with the results.
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.
Ho acquistato questo prodotto dopo averlo conosciuto attraverso una pubblicità su IG. Ero scettico ma ci ho provato. Ho seguito tutte le istruzioni utilizzando il prodotto per 30 giorni. Risultato? Nessuno!!! Anzi i capelli si sono indeboliti, pertanto, buttato e mai più acquistato. Ho lasciato anche una recensione sul loro sito che - guarda caso - mai è stata pubblicata. Azienda non affidabile.
