GR-7 Professional Reviews 

Hi all,

I am writing this review in order to save more people from buying this product. I think that this is a complete scam. I have bought it after I saw the video from Bryan Johnson grey hair reversal success video. I have tried it for several days. It has caused a severe irritation to my scalp, the smell is awful like it contains chemicals that could be harmful for the health. After the third day and having a severe scalp irritation I have stopped using it.

Then I have decided to search for more stories related to GR-7 and it seems that according to the dermatologists it does not contain anything that can potentially lead to reversing grey hair.
There is a review from dr Dray on Youtube and she is explaining in details why Gr-7 cannot work. (The video review is called Bryan Johnson's GRAY HAIR REVERSAL SUCCESS)

Do your thorough research before buying anything and do not be fooled by the positive reviews as they might be fake.

This product doesn’t work and customer service only ignore the emails.
After using the product following the instructions to the letter, the product didn’t work.
The indications said that you should see results after 7 days so I thought let’s give it time but after 1 month and 2 anti-grey bottles, I give up. I contacted customer service but they didn’t even bother answering my emails. I have to say that I use the shampoo too and this is a good product but the point is that the anti-grey lotion didn’t work.
Since the product is very expensive, I expected a better customer service but I was wrong. All in all, a big disappointment and I won’t buy GR7 products anymore.
If this help to anyone who wants to buy the product, my hair is dark (used to be), long and a bit greasy.

My hair had greying/going white from the temples, down to behind the ears. This product has reversed it entirely! I didn’t wash my hair for several weeks, but did rinse in shower due to sweat caused by exercise.

It’s had a continued positive effect, generally lightening my brown hair, giving it more sheen. A female friend even asked if I dyed my hair because it looked so good (she swore it was meant in a good way haha).

Anyways, have had great success and plan to continue maintenance use!

Good product, but will not get hair 100% dark.
It will hide some grey, but will look faded.
I followed the directions to a T , and I'm still trying to get to 100% with what I have left after a month of use.
I wish it would work better, because it's simple to use. Just not sure if it will or not

I doesn't work on me after 20 days. I washed it probalbly few more times than suggested. But after almost 3 weed the white hair are exactely like the first day, so I'll stop.

Still can't believe it!
I used it religiously the first 7 days, twice a day. Its a miracle. The only struggle is the bottle, you need to be really careful as you apply the product to the roots, as the bottle is not ergonomic.
Couple of weeks after the miraculous results, i had to use it twice a week but i couldn't make it due to some health reasons. Some of the hair that i regained the original colour gone grey again, but not all of it. Now i will go back to regaining process and i will use it twice a day to regain all again. Now i understand how important it is to continue using the product to maintain the original colour. (*used 2 bottles by now, 1st bottle finished as i regained my original colour)
Please come back with a better packaging and a bottle that can be used easily.
I recommended this product everyone around me!

I found this product from a Youtube video by Bryan Johnson on gray hair. My mom has jet black hair, but finally started to grow some grays.

Pros:
- Fast Shipping. I live in the USA and it shipped from their Poland warehouse fairly fast.
- Instructions are clear. Do not wet your hair for first 7 days, and continue with regular routine after. This was the hardest part for someone who is used to washing at least 2x/week or every other day.
- So far, the grays have started to reverse on her head! I was pleasantly surprised at how effective it is.

Cons:
- The formula has an odd almost vinegar smell, so you would need to maybe mask it with something else like leave-in-conditioner at the tips of your hair
- BOTTLE DESIGN. (This is the reason for the 4-stars insteads of 5). The product spills quite a bit due to the bottle not having some sort of nozzle or application to put directly onto the scalp as required, which results in losing a lot of liquid when you try to use it. For the cost of the product, I think the company should invest in better bottle applicators so customers benefit from the entire product without losing liquid volume.

Overall: would recommend to give it a try. I bought four (4) bottles and looking forward to seeing how my mom's hair turns out once she's done with all of them :)

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.

well it does what thety say. i dont know how but my hair is dark again

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.
