GR-7 Professional Bewertungen 246

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.

I am extremely satisfied with GR7 Anti-Gray Hair Treatment. After using it consistently, I’ve noticed a visible reduction in gray hairs and a return of my natural color. The application process is simple, and it fits easily into my routine. My hair feels healthier, stronger, and looks more vibrant overall. I appreciate that it doesn’t leave any harsh smell or residue. The gradual, natural-looking results have exceeded my expectations, making me feel more confident. It’s refreshing to find a product that actually delivers on its promises. I would happily recommend GR7 to anyone looking to restore their hair’s youthful appearance.

I used this from more than a month .. no result same grey appears..

High possibility of lead contamination!

I strongly recommend NOT buying this product.

About a month ago, as part of optimizing my diet, I carried out a mineral analysis of my body based on a hair sample taken from my head. Before I even received the full test results, the laboratory called me because they noticed an extremely high level of lead in the sample. The acceptable limit is 4, while my result was 936 - yes, NINE HUNDRED THIRTY SIX!

The consultant asked whether the sample could have been contaminated or whether I work in a smelter or another heavy industry environment. I ruled out both possibilities. I made sure the sample was clean before sending it, and I work an office job.

One possible explanation that came to my mind was the anti grey hair product GR-7 that I had been using. I started searching online and found several reviews on Trustpilot where other users claimed that independent tests had allegedly detected lead in this product, something the manufacturer does not mention.

Because of this possibility, I immediately threw away all products from this company.

I repeated the mineral test using body hair as the sample. Although the lead level was much lower the second time at 41.55, it is still a level indicating lead exposure in the body.

IT IS BETTER TO BE GREY THAN BALD BECAUSE OF CHEMOTHERAPY.

For anyone still considering using this product, I followed the manufacturer’s instructions exactly and used it for several months. The grey hair did become slightly darker. In reality it just turned yellowish. After cutting it, the new hair grew in grey again. So it was simply temporary coloring and not a real solution to greying hair.

My assumption is that this kind of marketing relies heavily on people’s naivety. In hindsight I feel I should have questioned it earlier when looking at the advertisements showing models with perfectly styled grey hair that appears professionally dyed and then supposedly magically reversed to dark.

Works as expected

Never received my order in the US. They emailed about delayed shipping due to tariffs. After a few emails they quit responding and kept my money. It’s been months. Beware USA buyers!

Great product, I recovered my natural color in 7 days.

Incredible effective product on my hair. It used to be extremely white (ice look) and became much darker. Absolutely recommended product!

Got charged, but never received email that my order got shipped. After 2 answered emails, had to contact my credit card company to dispute the charges.

This product works for me and I heartily recommend it. I'm 70 and I no longer have grey hair!

It actually works - I have bought this product multiple times over the last few years - and it actually works in reducing my grey hair. A lot of my friends colour their hair - not me. Simply because this works. I rub it into the scalp a few times a week. That's it.

I placed an order on Jan 11, 2026 and the order hasn't shipped. They said they are no longer shipping to the US because of tariffs. They shouldn't be allowing the order to go through from the US if that was the case. I have asked for a refund multiple times via email and they still haven't refunded my money. Scam site! Buyers beware!

Horrific ! Ordered Janaury 2nd, no tracking info was sent, not one email was answered and my social media message was read and also went unanswered. I originally heard about this company from Bryan Johnson and when I asked his company they made it clear that they do not endorse GR-7. It’s been a disappointing and very unprofessional experience. I have a PayPal account and expect a full refund.

I placed my order on December 21, 2025 and one month+ later as of 1/26/2026 it is still showing as currently Processing. I sent a couple of emails to customer service to see when will it ship and no answer.

This is miracle stuff.
I was VERY sceptical. Used it for 2 weeks, twice a day… and my grey sides have regained their original blond color.
Now I keep up once a day.
I should have done before and after pics… but since I was pretty sure this wouldn’t work I didn’t 🫣
Might work differently on different kinds of hair. I definately recommend it!

Ordered almost 1 month ago, paid over $50 for 3 day shipping, package NEVER shipped.

It’s been a week of using the product. I have long dark hair with some grey hairs here and there, I have not seen results yet but I am willing to keep using it. It’s been costly though to use this product since it gets consumed very quickly.

I have been using their natural hair color restore product for over a year , it works and far healthier than hair dye. Also they ship so fast to Australia, Thank you GR-7 your product is unmatched.
