GR-7 Professional Reviews 

Took 6 weeks to receive the product. It is like they had Christopher Columbus transport it on the Mayflower and then used horse and buggy to get it to my house. And charged me a delivery fee for that privilege! INSANE
I get orders from China in 2 maybe 3 weeks with free shipping. So totally unacceptable.

So far so good. Interesting product. It seems to sort of bring out the natural colour of the hair itself rather than from the follicles. I shaved a bit to close and it went back to grey. So basically it activates some sort of colour pigment in the grey hairs to turn them the natural colour rather than dying them.

Delivery was good, as expected. The product really does work for me. It took like 3 weeks as described and you really need to be consistent. Not sure if I used more then is actually needed and if that matters much versus consistency of application

Both me and my wife have been using the product for 3 weeks and have noticed our hair thicker. I also use the gray removal solution now for 1 week only and am noticing a difference. I am very impressed with the product and seems to be delivering.

Used for about a month now, notable reduction in white hair

I think I might see a difference, but need to continue to be sure

Seems to work. I have only used it for a couple of weeks now, but my hair looks nice and natural. Not sure if the color is restored or if it's a dye though. Either way it's pretty easy to use and results are good. I wish there was some applicator on the bottle.

Still testing the anti-grey & hair regrowth products..Products are inexpensive & will continue to use them

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.

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!

Have been enjoying this product for 4 weeks now. Have seen a shift starting in a few weeks, even though subtle.

It seems working, after a few days. Let's go ahead.

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.
