GR-7 Professional Reviews 

It is just a very expensive hair dying product, it has nothing to do with stopping the hair from turning grey again.

I only used it on my temples, well it does darken the grays a bit, but some drops always landed on the root of my ears. By next morning my ears turned black wherever the dripping was.

So it is not hard to guess that it has some coloring additive and its not your pigments.

10 days no hair wash. Smell not great. Day 15 95% grey hair gone. Wife and I agreed not a chance this could work. Maintenance now.

You have nice result. But it is anyways a method with a coulouring agent.

Great product , works great restoring the natural hair color , very recommended!!!

Habe das Produkt mehrmals gegen graue Haare bestellt.

Schneller Versand. Hochwertige Verpackung. Habe die Produkte das Tonikum, Kapseln und Shampoo ca. 2,5 Monate genutzt und das Tonikum 2 x täglich genutzt. Das Tonikum ist transparent von der Farbe aber beim Auftragen wird es braun. Vom Einmassieren hatte ich immer dunkelbraune Fingernägel. Irgendwann habe ich Handschuhe beim Einmassieren genutzt. der Ansatz wurde sehr dunkel und passte nicht mehr zu den blonden Haaren. Habe es abgesetzt und die Haare wurden nach dem Waschen heller wie nach einer Tönung. Für mich hat das Produkt nur bedingt funktioniert. Es erspart ein paar Monate das Färben aber hatte die Haarwurzel nicht verändert. Da die Wurzel tiefer liegt stelle ich mir nachhinein die Frage ob ein Tonikum da überhaupt helfen kann. Es ist aber das beste Haarwuchstonikum dass ich je benutzt habe daher 3 Sterne. Ich habe viele neue Haare auf dem Kopf bei dunklen Haaren kann es das Färben hinauszögern oder gar ersparen, bei blonden Haaren leider für mich nicht ganz passend.

Delivery time was great. Product was even better! White hair turned golden at first, then darker over time. Noticeable difference. Especially, when compared to before and after a month photos. I would definitely recommend this product to try!

The team is really kind and quick to respond to my questions ! And the product is quickly working well to turn my grey hairs to almost the original colour within only 2 weeks. Wonderful !

This product works and really well. I use this on my beard and it has done an excellent job of reversing my hair back to my natural color. I buy them 4 at a time.

For me this was the only product that made a noticeable difference with darkening my grey hairs. I tried other competing products, where one made no difference at all and another resulted in skin eczema reaction. The GR-7 works well for me and my sensitive skin.

I have been using the GR-7 No More Grey fluid for a while now and wanted to report it really does work. I have auburn hair that had silver along the temples. After using the GR-7 for a couple of weeks and now just once or twice a week both sides are fully their original colour without a hint of grey/silver. This has worked well on my beard too. Worth every penny!

Apart from a few hair looking less white , have not noticed any change after using twice a day on the side of the head for 4 weeks, may order another bottle so see if greater affects.

I am following a longevity protocol for some years. One of the longevity experts I follow is Bryan Johnson who, in his original Blueprint was mentioning this product as a supplement meant to support the reversing of grey hair. Along with Mayraki products which I do not recommend. They stain horribly. Bryan himself mentions this. I started therefore ro use this product years ago and successfully. Now, I only need very sparingly to apply it, at times when my temples start going grey again. I don't even follow the instructions to apply it regularly, morning and evening for seven days. My hairs turn back to their original, dark colour after a few, occasional applications. I am sorry I didn't make pictures of myself before and after. I am almost 59 now.

Great product, fast shipping, real results.

Bonjour,
J'ai fait deux commandes de GR7 et je n'en ai reçu qu'une seule. Maintenant je galère pour avoir quelqu'un qui puisse me répondre. J'ai été débité 2 fois 162,5 euros, ce ne sont pas des petits montants. Et personne ne me répond. J'ai bien reçu une mais la 2nde. Qui pourrait m'aider?

It just doesnt work. And i got a terrible allergie in my scalp. Its not very pleasent to use and not to wash your hair for so many days. I showed it to my dermatologist that is from the same country, she checked the formula and told me that this product will never work.

good product that I have used for over 5 years - super easy to use!

I have been using this product since over a year, and if one follows the directions the result is amazing. No more dyeing hair, just a few minutes a day to achieve my own colour hair, then a weekly application to maintain it. Remarkable product.

I used this product on my grays but the maximum result I got after following all instructions perfectly, was a yellowish colour.
But the worse is yet to come, I started shedding hair at a rapid rate. I had to go on holiday and stopped the product and my hair didn’t fall anymore. Once back I went back using their product and the hair started to fall again. There is too much alcohol in there GR-7 which promoted hair fall.
I sent them an email asking weather this was only my case or someone else had the same experience but nobody ever replied. I also sent them a picture of my scalp, nothing whatsoever from them.
