I have used my third bottle and I am hopeful this will work. My hair is in better condition and I can see the grey has started to blend very slightly. I am hoping with another bottle I will achieve the desired results. I will leave a further review to update.
This product is truly a game changer - lives up to the bold claim
I decided to try the Grey hair treatment from GR-7 but was a little bit sceptical about it working. I put it on the areas where I had grey hair (probably just under 10% grey coverage originally) twice a day and didn't wash my hair for a week. I was totally AMAZED - by the end of the week, all the greys had gone back to my original dark brown colour! 4 weeks later, and i still use it once a week to top it up and love having my colour back!! would totally recommend. Can't believe this product isn't being shouted about more on social media!!
Works on the beard
I have actually been using it on my beard and I'm seeing a notable difference. 3 weeks in and definitely the sides of my beard I can see changes. Hopefully after another couple of weeks i'd be able to see the the hair on the chin area return to its natural colour.

I tried several products to turn my white hair to their natural shade but nothing worked untill I used this magical product by GR-7.I have been using it for one week and now I can see my white hair are almost vanished completely. I believe it will make them further dark in next couple of weeks.
I've been using this product for about a month now. I no longer have to dye my hair with color, I have only used GR7. A lot of hair is growing back to my normal hair color. I'm super happy that I no longer have to use regular coloring as they often smell too chemically and aren't good, plus it takes a lot of effort to color your hair every two weeks. I have had very good experiences with GR7, the solution smells very mild, it does not bite the eyes like conventional dyes. I also find it easier to put these on the scalp, I use a small spray bottle and spray onto the scalp. Most of the hair is no longer grey, only a few, but it is hardly noticeable. Many thanks to the team, a great product...I can only recommend it, it would be nice if I could buy it in Germany and it wouldn't be too expensive.
I thought it was probably a scam but bought a bottle anyway; hoping I would be wrong. I applied the liquid twice daily and by day three I started to see my grey (white) hairs turn yellow. It's now day 8 and the bottle is almost empty, but my hair colour is almost completely restored. I still have some 'lighter' areas but for the most part, I've gone from silver to dark brown in a week! What I find amazing is that it's my natural colour and the hairs have turn brown from root to tip. I did not know that was possible, if anything I expected it to grow out from the root slowly..
For anyone wanting to turn the clock back, I cannot recommend this enough. I'm yet to find out if my colour stays when I reduce the frequency of application but there's no turning back now. It's a surreal feeling to be grey for 2 decades and within a week, go back to the hair I had at 16! thank you GR-7. I hope you can reduce the price and come up with an application tool because it's quite tricky getting the liquid onto my scalp without wasting precious drops and also wetting my hair. I found that filling a small thimble and dipping my finger into it works well most of the time. Apart from that, I can't thank you enough!
Hi, I just start using GR-7 professional, its being a week so early days, i notice my white hairs are turning yellow or greyish, I dont have any reaction so all good.
will update you in a month with progress.
A really effective treatment for grey hair reversal
A really effective treatment for reversing grey hair growth. This is not a short term dye. Long term application is needed but in reducing amounts. It genuinely took only 3 weeks for my natural hair colour to return.
really like this product. I had dyed my hair for years and then we went through closed salons so i let it grow out. started using GR 7 last year in april and my hair colour went from grey to a light browny, blonde shade
plus the quality of my hair improved.
