GR-7 Professional Reviews 

No white hair after 10 days!
Beard needed longer!!!
Top product!!
Thanks a lot. Max

Some parts of my hair are showing some yellowing from gray, which I assume is a good sign. I am not sure if this will work to my expectations, but can only keep trying.

I did use the product for 3 days without a shower but had to re-start my daily workouts and showers and made sure to apply after my shower and before bedtime. Unfortunately the product made no difference. Only thing i can try next is to not excercise, shower or get my hair wet for maybe 7+ days and see if it works. I didn't know your hair can't even get wet. I recommend a long tube be added to the bottle for application so it gets to your scalp better and not in your hair since this stuff is soo expensive!

Been dying my hair for over 10 years until now! This product really works !!

The product works incredibly well. I bought the No More Grey Hair and it is mind blowing! Highly recomended. Also I wrote an email to the team and the reply was fast, efficient and super kind. So for me, it is more than perfect.

I first heard of GR-7 products on Bryan Johnson's Blueprint Protocol site. I've been dying my grays for years and the No More Greys hair treatment sounded like a dream! If a product can unwind time, why not?! I purchased one bottle of the No More Greys hair treatment and two bottles of the Anti Hair Loss Lotion (I had planned to give a bottle to my mom).

Shipment to the US was quick, especially around the Christmas season. I was excited to try after reading many positive reviews. The application was easy to apply. Christmas was the perfect time to use this product. The instructions recommended to not wash hair for 7 days. For the best results, apply morning and night. I followed the instructions and wear a shower cap to sleep. Nothing happened. My grays were still gray. My hair was clumpy and smelled like something was burnt. It transferred to my clothes, pillow cover, towels. To this day, I still can't remove the odor.

The Anti Hair Loss Lotion is a spray. It smells like a cheap man's cologne. The smell stays with you throughout the day/night. It'll also causes you to cough after only a few sprays.

I emailed the company with the above experience and asked for a refund, they replied with, "While we take all customer feedback seriously, I would like to reassure you that the active ingredients in GR-7 products, are safe for use on your scalp and hair. However, we understand that individual preferences may vary, and we apologize for any discomfort caused." I never mentioned whether it was safe or unsafe. They don't issue refunds.

This product is not a one size fits all that works for everyone. If they believed their own product is amazing and it works, why not refund for the subset of people it didn't work for? I don't understand their business model or their product. The experience was awful. Save yourself the headache. Look elsewhere.

I have used it for two months and it changed my grey hair to a partial yellowish red. That's it. I have used two bottles but there's no change. Lost hope, I think it is not effective.

The product worked just as promised. I was anticipating the worst, but was pleasantly surprised. It was easy to use and the results are very good. I'll keep buying.

Early days yet but impressed by the ingredients which make up the product, I think they will actually bring additional health benefits.

I see it's working. In my case it's a bit slow, i have done it for 2 weeks now and i just start to see some results.

I’ve had grey hair for 30 years, this product is working however I am using Hyperbearic oxygen, Nmn, spermidine with it. The results are truly amazing. I can see a 70 percent improvement in the first 5 days. Will keep using it for a month.

I'm on day 15. So far I see a very slow shift in my mostly gray hair to a light orange shade. I look forward to continuing this treatment with the next bottle until the hair darkens closer to my original dark brown color, and hopefully go into maintenance mode after. Putting it on is messy and it tarnished my silver rings. Hope they can figure out a better way to pour out the liquid.

Amazing, in 7 days it worked! Will keep using this great product.

Ipak 4 zvjezdice, na početku sam dala 5 zvjezdica jer nakon što 3 tjedan ovo koristite redovito i kao je na uputama, vama će sigurno vratiti se boja, ostat će pokoja sijeda no rezultat je impresivan. Sad kad sam prestala koristiti vidim da mi ponovo raste sijeda :( tužna sam, očekivala sam ipak malo dužu promjenu, ovako izgleda da djeluje kao neka vrsta farbe. Iako sam razočarana što nisam dobila ono što sam mislila da ću dobiti, kupit ću ponovo i tretirati opet. :)

10 days in. Bottle nearly gone. I can’t tell if it’s doing anything yet. I think I’ll order another bottle.

I love the Hair Support vitamins I have noticed a big difference in my hair loss after a few weeks already. It doesn’t upset my stomach and so far no breakouts from this formula. Great product and will be ordering more.

I gave this as a gift to my dad and he loves it!

Product ships quickly in spite of my continued speculation it works, in my case hair color is not consistent but I would be mostly white.

It really works! Brings back naturally look colours and this just as far as after 10 days of use, 2 applications per day 5/7 and 2/7 1 application per day. Now I will move to 1 per week as per instructions.

Ordering is easy. No results yet it has only been a month
