We were pretty sure it was going to work based on the referring source, but we were really surprised how effective it was. It works!

If I could give a zero star review, I would. Company made a mess of customs. Said would refund (has not). Then I receive a $250 invoice for customs from UPS (they said they would fix that, have not). Stay clear from them.

Absolutely worked within a few short days!!! Maybe the fact that I don't smoke, nor drink alcohol may indeed help, but I could literally see my hair go back to their natural color within the first 4-5 days! HIGHLY RECOMMEND!!!

i have been trying to contact them for a refund because they lacked and delayed my delivery upto 15 days and now they are not replying nor giving my refund. extremely disappointed in their services, they have poor customer service and supply chain/delivery management.

The jury's out. Took the pills for 4 months and didn't see real improvement yet.

A product that does what it's meant to! My mother colours her grey roots every two weeks. About 6 years ago, she had a sudden allergic reaction (to the same hair dye she'd been using for over a decade), which involved several trips to the hospital. It made me realise how toxic these dyes are. I have only some grey hair, mainly around my ears and temples, so I wasn't dying as often as my mother. However, my mother's experience scared me, and I discovered GR-7 as a natural alternative. I was hugely sceptical when I first started using GR-7. It's a cloudy, watery solution that doesn't smell of much. I wondered how on earth this stuff could bring back the colour to my hair. I followed the protocol to a T (use twice a day, no washing hair for several days, etc) and was amazed when it started to work. It's certainly not an overnight transformation. My grey hairs became an interesting shade of burnt orange for the first two weeks. Personally, I liked it as, against my naturally off-black hair, it just looked like I'd had highlights done. I suspect some people may not like having orangish hair for a week or so, but I urge you to persevere! After 2 weeks, my natural shade of off-black started to come into the grey hairs. Some of the greys are 100% back to their natural off-black colour. Others are darker brown. However, I like this as it looks far more natural than the monocolour I used to get from dying my hair. The only slight criticism is that the maintenance regime is meant to be a once or twice a week application. When I dropped to the maintenance application, my greys started coming back with a vengeance. Therefore, even though I've been using GR-7 for 6 months, I still apply it every other day. This does mean I'm paying more than I expected to when budgeting. However, if paying a little more is necessary for a product that's natural and doesn't contain reaction-causing elements, I'm in. I haven't dyed my hair in six months and will never dye it again!

I’m on my third bottle so far and I’m sticking with it because I can see some progress but it’s a slower process and more costly than originally thought. My hair definitely seemed overall darker in the first week but as my dye faded, there was a number of weeks where I was showing more and more grey hair, before it started to turn yellow. I realised that although I used silicone-free shampoo and conditioner, I did use some hair product with silicone, so I continued after swapping product. I saw a lot of reviews before buying that mentioned the terrible smell but thought that was a lot of fuss about nothing. I saw the video about applying it and found it to be pretty unhelpful – it demonstrates only one spray and rub of the head, so you don’t get to see what ‘systematic application’ looks like, which is stated to be crucial. It also doesn’t come in a spray bottle. I put mine into a spray bottle and it got clogged up after a while, so I reverted to the supplied bottle and then latterly have been using a syringe. I noticed that all the photos of results are of people with short hair, which is obviously the easiest type to treat. When you have a big mop of long hair, it’s hard to make all the required partings to get to the scalp and to treat all around the back of your head when doing it yourself. It’s also difficult to not let a whole load of liquid out of the bottle when your head’s upside down. I’m sticking with it for one more bottle because when it gets to the stage of using it once or twice a week (I have been using it daily or twice daily for 2 months now) then it would then become cheaper than dying my hair at the hairdresser’s.

In just over a week of using GR-7 my grey hair completely disappeared! I was at first doubtful but easy to use and apply and the grey hair started to lighten and eventually went to my true hair color all within a week

This stuff is excellent. Works well, and no colour choosing necessary! Restores natural pigment. You have to keep it up but definitely keeps my hair nice and dark.

Très bien, le shampoing et la lotion sont doux et sentent très bons. La production de mélamine fonctionne et les cheveux gris disparaissent effectivement.

Ich war anfangs skeptisch, ob das funktionieren kann, aber es wirkt. Jetzt nach 3 Wochen habe ich deutlich weniger graue Haare. Ich denke in ein paar Wochen sieht man kein graues Haar mehr. Es ist gut aufzutragen und ich habe es gut vertragen.

So far the product has lasted a long time and I starting to see some darkening of the hair follicles after a month of use.

This products works well. I used for men for years despite having a reaction to my skin. I wasn’t sure about GR7 when I saw Bryan Johnson using it and I said to myself let try it and see what happens. After I placed my order I started watching videos on TikTok some positive some negative. Then my order arrived and start using it. I followed the instructions and applied exactly as it says for 7 days morning and evening. Then the results were hard to tell but didn’t give up carried on applying for another week and that’s where I started noticing that my hair colour was totally changed and what surprises me is that my hair colour were my natural hair colour. This produces is working and if anyone using dying products made of chemicals, I think it’s time to get yourself a fever and try Gr7

Can't buy it! I'm in the US and have tried every payment type and it won't go through. I've emailed them multiple times and cant get a response.
