GR-7 Professional Reviews 

I’m not satisfied with product and it’s doesn’t not deliver what’s promised regarding reverting gray hair to original colour.
I have followed the instructions and 8 days in without seeing any results!
I regret the purchase!

Have been enjoying this product for 4 weeks now. Have seen a shift starting in a few weeks, even though subtle.

It seems working, after a few days. Let's go ahead.

After two weeks you see a change. But I needed rather 3- 4 weeks (two bottles) to have all the grey disappeared. For the rest, it works amazingly

I only purchased one bottle per Bryan Johnson’s recommendation. GR-7 seemed to have worked modestly in the area where I applied the product. It has been one month. I decided to buy two more bottles and see how it eventually turn out to be.

After first week of daily applications have not noticed any change.

I ordered this product on February 12. Paid for FedEx delivery. It still hasn’t been delivered.

Great product, been using for a month now and noticing a difference with the colour of the hair coming through.

At first few days of using I thought my hair was breaking and falling off and then after which I continued I saw improvement in the thickness of my hair and also my grey hair has become better but still not turned completely dark .,almost I finished my first bottle planning to order again and hopefully to see one hundred percent resukt ..it helps it does help

I have been using this product for 3 weeks, but I don’t see any change in my hair color.

It works. In 3-4 weeks grey hairs went back to normal color.

Better to combine with oral tyrosine and a stem cells release supplement.

No funciona. Tan solo consigue darte un ligero color amarillento/parduzco en las puntas, por el propio color del líquido imagino. En mi caso que soy moreno, no vale para nada. Además te deja un terrible olor a pelo chamuscado que se queda en la ropa y en la almohada. No lo compréis.

I used this because Bryan johnson recommends this, and it works. For real my gray is naturally returning to my natural color thank you GR 7

I'm really impressed with GR-7; I was very sceptical at first as I've tried other hair colour restorers, which just weren't effective and stained my skin, finger nails (and walls), but the results of GR-7 speak for themselves - the manufacturers also offer a 50% discount on a follow up order (40% + 10% under two codes) if you send before and after photo's for use on their website (which I have done), which they definitely wouldn't do if their product was no good. It is also not messy (does not need applying with gloves) and doesn't leave a sticky or greasy residue, although perhaps a mist pump spray option would be a useful addition to get a more even application.
I use a spiky silicone scalp massager to rub in the GR-7, which may or may not help, but it does encourage blood flow to the area, so logically it should help.
It is also working well on my beard (and a little on my chest area - only started trying there more recently) even though they say not to use it anywhere other than on the head, as they haven't officially tested it's effectiveness, but in my unofficial opinion, it does work for beards.

order was placed 12th feb and no answer from support or any updates on the shipment of the order.

It works.

Most of my grey hair is gone.

It took a while though for the hair to revert back to the original colour. It could be becasue I was using too little and it required more liquid. After 10 days, I still had half bottle full. Then I decided to use more liquid and applied it only to the sides of the hair, the area with more grey hair. After 10 days, the hair started to revert colour.

Highly recommended

What a gamechanger...having dyed my hair now for years, and watching it break and get damaged, was certainly surprised at how amazing this tonic was...its a little daunting at first, and you feel unsure, but BOOM, it works, AND my hair is healthier and growing again, feels fantastic! I really poured through the first two bottles, but after that, its become an easier process, and am using less than expected as i go along weekly...THANK YOU, I am a customer for life!

First of all, I wasn't looking for a way to prevent or dye gray hair, I had already embraced the fact that gray hair is part of growing older. However, I am interested in longevity to grow old fitter, so I came across GR7 via the Blueprint Bryan Johnson website. Out of my curiosity I ordered the gray hair lotion and the product was delivered quickly.

I hadn't told my partner anything and she was skeptical about the product and the possible outcome. Went on a winter sports holiday on January 19, 2024, which was a great moment for me to start the metamorphosis. Normally I wash my hair daily, so I wasn't happy about not washing my hair for 7 days, but it wasn't too bad. It must be said that it is a strong smelling lotion and after 7 days of massaging twice a day the hair does not feel dirty or greasy but it does smell very strong, but the result is amazing.

It is a real GameChanger 2.0, from a salt and pepper look with gray flanks, my hair had already transformed from gray to the predicted yellowish look in the 1st week and at the end of the week it tended more and more towards my youthful hair color. Now at the end of the 2nd week and starting the 2nd bottle of lotion, the yellow color has given way to a brown head with hair that is still getting darker. Another week and then I can suffice with a maintenance dose of once a week and hope that my gray hair stays away.

Compared to hair dye, it looks like an expensive product and it is, but if the maintenance dose keeps my hair in youthful condition, it is relatively cheap, it gives my self-confidence and appearance a huge boost and therefore meets more than just the product expectations.
