The 'GR-7 No More Grey Hair' product worked well on my grey hair. I am a young guy, 34, but still managed to reduce my gray hair by probably 50%. The bottle lasted me for 16 days (twice/day). Next time I will test it on beard too.
While expensive to ship to Canada, I'm happy with the product.
I was really sceptical of this initially. But when recommended by Bryan Johnson I decided to give it a go. I've had greying in my temples going for about 5 years. After applying this twice daily, I started seeing yellowing of the greys after about 5-6 days. I found applying the liquid was the most effective by tilting the bottle while at the same time holding it onto the scalp. I'm about 1/2 bottle in at 10 days now and the greys are FAR less prominent on both temples. on my left temple, I can't seem to even find the grey patch previously visible. Will keep going with this. Hoping to only apply it once weekly for maintenance after the initial period. Read the instructions carefully and be systematic in your approach.
it works!!!
I’m not satisfied with product and it’s doesn’t not deliver what’s promised regarding reverting gray hair to original colour. I have followed the instructions and 8 days in without seeing any results! I regret the purchase!
After two weeks you see a change. But I needed rather 3- 4 weeks (two bottles) to have all the grey disappeared. For the rest, it works amazingly
I only purchased one bottle per Bryan Johnson’s recommendation. GR-7 seemed to have worked modestly in the area where I applied the product. It has been one month. I decided to buy two more bottles and see how it eventually turn out to be.
After first week of daily applications have not noticed any change.
something that might actually work
Great product, been using for a month now and noticing a difference with the colour of the hair coming through.
At first few days of using I thought my hair was breaking and falling off and then after which I continued I saw improvement in the thickness of my hair and also my grey hair has become better but still not turned completely dark .,almost I finished my first bottle planning to order again and hopefully to see one hundred percent resukt ..it helps it does help
