Great product!
Had a good experience with this product! My hair grew in thicker so the grey is less noticeable. The product has a mild scent, so it was pleasant to use.

Had a good experience with this product! My hair grew in thicker so the grey is less noticeable. The product has a mild scent, so it was pleasant to use.
The delivery was prompt, even in the United States. The product works! I shared before and after pictures (after 3 weeks of use) and there is a noticeable difference. The change is natural, and the hair does not look fake and dyed. I look forward to continuing to use the product and see results after longer use.

Whilst browsing the independent "Don't die" "Blueprint Protocol" webpage I found a link to GR-7's 'No More Grey Hair' product under 'CASE NOTES DECEMBER 2021' which said: 'We’ve made some meaningful progress with this formulation'. I was very sceptical, not least because if it's so good, why isn't the entire World singing the praise of a product that has been in use for almost 2 years? Recognising other health-related suggestions on the Don't die website with what appear to be honest appraisals that match my own experiments in the past, I decided to try it out. Poland-based manufacturer GR-7's website explains how it works and their UK distributor promptly answered all of my questions. I bought what I could justify spending to find out whether or not it worked. After 2 weeks of daily application I was pleased to find a very visible change of a large amount of grey hair around my temples back to its normal dark brown colour. I can't guarantee GR-7 No More Grey Hair will work for everybody but it does work for me. You must however follow its instructions to the letter and given it's not cheap, I did exactly that. I highly recommend trying this product if you want a healthy way of restoring the natural colour of your hair.
Tried this sceptically, but to my shock and amazement, wow! The results after only one week were incredible. Followed the instructions and avoided washing my hair and used twice a day for the first week and almost all of my grey is gone in only one week.
This actually (surprisingly!!!) works!!! Takes about 7-10 days to see result but it does work! Color is coming back!!!
The best product
The GR7 Real Shades definitely does work and reversed around 95% of grey to original brown color by 3.5 weeks. The temple area is stubbornly resistant, changing slower. I stopped leaving it in 24 hours a day after the 5th day because I couldn't stand the smell and texture while sleeping. So my results are with 12 hours a day and washing hair each night. You have to be patient and keep with it.
I started using it and I could start to see the change after a few days. I am only in the early phases but will update my review as I see more progress 😃
I started to have lots of white hair and instead of coloring them i wanted to try this product. It’s been a month now (first week without washing+ using twice a day then once every other night) -1bottle last for the first week intensive application, i then bought a second one since the delivery is pretty fast! -> The application is easy and dry fast if your hair gets wet without getting heavy -> I definitely see an scalp and hair quality improvement which I’m super happy about after 1month -> white hairs are way less visible and seems getting slowly color back Interressting product and composition . Trusting the process
Started with absolutely white hair. After 3 days of using GR7 in the morning and evening there was a darker shade in the hair. After a week hair turned a bit gold colour which fits good because I have been a very light blonde as a kid. It also worked on the beard, which is amazing. Looking 10yrs younger now. 1 bootle and still like a third left to use it once or twice a week.
5 stars for how quick (and well) the Real Shades of Hair works which is the most important thing; within two days I could see the colour start to change. However, 2 stars for the bottle design, the squirt applicator is not good and causes a lot of wastage, a spray nozzle like the Anti Hair Loss treatment bottle would be much better.
On the side of my head i had a few greys im 37 and they disappeared after 14 days of use. I haven't as yet left it for a period of time to see how long this works before you need to reapply. Ive also used on my beard but i have seen minimal improvements im going to keep apply for another 2 weeks on that area and see if it just needs longer. I brought this for the greys on my head so im happy that this worked if it does help with my beard that would be a bonus. But im unsure why this hasn't had as much exposure in the media.
Fast delivery. Product seemed to work first week. Decided to buy the shampoo too to compliment and hopefully synergistically work better than just the lotion alone.
Very happy with my purchase have been using for 3 yrs + now , just wish you did larger bootles .
I am age of 32 and my all hair turning grey and i used many hair oils and creams and some medicine but didn’t help . But this one GR-7 anti grey helps me alot and i can see the difference now . My hair start turning to black now to its original colour
2 weeks and all grey gone !
