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'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.
Some parts of my hair are showing some yellowing from gray, which I assume is a good sign. I am not sure if this will work to my expectations, but can only keep trying.
I did use the product for 3 days without a shower but had to re-start my daily workouts and showers and made sure to apply after my shower and before bedtime. Unfortunately the product made no difference. Only thing i can try next is to not excercise, shower or get my hair wet for maybe 7+ days and see if it works. I didn't know your hair can't even get wet. I recommend a long tube be added to the bottle for application so it gets to your scalp better and not in your hair since this stuff is soo expensive!
I first heard of GR-7 products on Bryan Johnson's Blueprint Protocol site. I've been dying my grays for years and the No More Greys hair treatment sounded like a dream! If a product can unwind time, why not?! I purchased one bottle of the No More Greys hair treatment and two bottles of the Anti Hair Loss Lotion (I had planned to give a bottle to my mom). Shipment to the US was quick, especially around the Christmas season. I was excited to try after reading many positive reviews. The application was easy to apply. Christmas was the perfect time to use this product. The instructions recommended to not wash hair for 7 days. For the best results, apply morning and night. I followed the instructions and wear a shower cap to sleep. Nothing happened. My grays were still gray. My hair was clumpy and smelled like something was burnt. It transferred to my clothes, pillow cover, towels. To this day, I still can't remove the odor. The Anti Hair Loss Lotion is a spray. It smells like a cheap man's cologne. The smell stays with you throughout the day/night. It'll also causes you to cough after only a few sprays. I emailed the company with the above experience and asked for a refund, they replied with, "While we take all customer feedback seriously, I would like to reassure you that the active ingredients in GR-7 products, are safe for use on your scalp and hair. However, we understand that individual preferences may vary, and we apologize for any discomfort caused." I never mentioned whether it was safe or unsafe. They don't issue refunds. This product is not a one size fits all that works for everyone. If they believed their own product is amazing and it works, why not refund for the subset of people it didn't work for? I don't understand their business model or their product. The experience was awful. Save yourself the headache. Look elsewhere.
The product worked just as promised. I was anticipating the worst, but was pleasantly surprised. It was easy to use and the results are very good. I'll keep buying.
Early days yet but impressed by the ingredients which make up the product, I think they will actually bring additional health benefits.
I’ve had grey hair for 30 years, this product is working however I am using Hyperbearic oxygen, Nmn, spermidine with it. The results are truly amazing. I can see a 70 percent improvement in the first 5 days. Will keep using it for a month.
