GR-7 Professional Reviews 

Love it. Easy to use. Unlike Mayraki it didn't stink and it didn't stain

It really works, and quickly. Goes a long way. Once hair is at the darkness you want, can top up less often. Can leave a grey/white streak if you like. The shampoo is also very good.

I have started 3 weeks ago , my grey hair is become a light brown but i will use at least 3 months , I am really happy and I will share the results asap.

started using it and saw results within 9 days. My greys are still there not much less noticeable. I will continue using.

It works. Without any dye my hair goes back to brown, and the little greys go away.

Amazing. This is like pure magic. It’s perfect for hair but if you want to do your beard or other parts just know it may take longer as that hair grows differently. I highly recommend this product. Just follow the instructions.

I love this it works brings my natural colour back it’s like magic

Très agréablement surpris ! J’ai pu voir le résultat dès la première semaine !!! L’odeur n’est pas terrible mais ça vaut le coup et certains cheveux sont passés de jaune à marron puis enfin la couleur naturelle. Je recommande !

It works, it is amazing !

Great product, just wish it has a darker colour option for black haired people, otherwise happy with the product

Within 7 days, my hair was turning darker. I was heavily grey on my sides and now it is starting to turn! Hoping in a couple of weeks it is fully natural dark hair again!

Quick service,
Fast delivery

I ordered a product which I never received. After contacting customer service (which was consistently rude and unhelpful), I requested a refund. It took countless emails before I received only a partial refund.

They claim to have sent the remaining amount in euros, but used their own currency conversion, which resulted in me getting less than what I originally paid. Very unprofessional handling and misleading refund practices. Avoid.

The best thing i ever tried .

I'd love to give a positive recommendation as the product works for me. But this time, importing it into Thailand caused the product to be impounded and only to be potentially released through a weeks-long process and costing double the original price of the product plus shipment. I therefore had to abandon the product with customs.

I find it inconvenient that the product “GR7 Real Shades of Hair”doesn’t come with a dropper or a pointed tip for easier application. After 2 weeks of regular use (morning and evening) and washing my hair once a week, I noticed that the hair near the crown seems slightly darker at the roots, but not on the temples — possibly due to slower growth. I will continue using it for another 2 months to assess the results. So far, no visible changes despite strictly following the instructions. I recommend including a dropper or redesigning the bottle tip for easier root application — like in hair growth sprays, which are much more user-friendly.

It works. But you need to be patient and commited to it. I bought first just 2 for grey hair. I saw results but after like 3-4 weeks. But like i said i was very commited to it. Then i bought 4 pieces at once (cheaper for the delivery). Now im using it like 2 times per week and im happy about the result. i can recommand it easily

I’ve been using GR7 for about 3 weeks. Skeptical at the beginning but after three weeks I can see difference. Very good product I highly recommend it.

I’ve been using GR-7 for a while now and I’m extremely satisfied with the results. It works exactly as advertised, delivering noticeable improvements without any side effects. I was a bit skeptical at first, but after consistent use, I can confidently say that this product does what it promises.

I've been using it for a month now, but I haven't been seeing much results..I'll keep going for another while, but so far I'm not sure.
