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.
This product has changed my look and my life. At first I wasn’t sure how it would affect my hair and what colour it would turn out. I had been expecting a bit of colour but this has been life changing. It’s exactly as advertised and I would highly recommend it.
Con me sta funzionando. Dopo 10 giorni di trattamento vedo grandi miglioramenti! Penso che proseguiró 2 settimane prima di fare il mantenimento
I had an effect after just a week of applying morning and before bed. Also only washing the hair every third day. The reason why I can't give it 5 stars is that there is easy way to apply the liquid in the scalp, so i had to try differens techniques. There was no recommended way of applying the liquid.
I thought I'd give this a go and am pleased to say that yes it absolutely works. I applied as directed for 21 days and now have my natural hair colour back instead of grey hair. Pretty amazing really!
This product really works. I am 56 and had some grey hairs, but they turned light brown like the rest of my hair. Blends it perfectly and looks absolutely natural. Been using it for two years now. Make sure you follow the usage instructions
Ordered a pack of 4 GR-7 bottles, package arrived open and 1 bottle was missing. Avoid the UK vendor, go to the EU site. Expect you will not receive the full order.
Honestly not what I hoped for. I switched to mayraki products because they are more natural and actually work.
I have been using GR-7for almost a month. All my grey gone but, still have yellow/redish hear. Hoping this will go in next few weeks.
Ten out of ten for this item, used once a week, I am 70 and would be a real grey if it wasn’t for GR7. But this is excellent the best I have tried. Been using it for 3 years now and would not use anything else.
I am very happy with GR-7. I am not quite done with the 21-day, once-a-day treatment, but my hair has quite a bit of color again. I had become completely gray due to aging. I'm 61 years old. My hair was originally blond, then gradually turned light brown over time, then finally gray. Now my hair is a combination of light brown with some red and golden, and of course some grays still. Some of the hard-core grays on the side of the head have turned kind of golden; you can tell they are grays with a hue, but just overall my hair looks so much better. I do not want to look dyed, so I like the mixed look GR-7 has given me. And yet, I think things are going to continue to change with GR-7. Another plus is that my scalp seems to be healthier as well. In particular, I had several of those stubborn so-called precancers (scabs) on my scalp; the kind that dermatologists like to cut or freeze out. I had already dealt them a pretty good blow using a combination of items I put on my head (vit C, castor oil, etc.). However, I noticed that the three that just would not completely go away, went away after about 2 weeks of applying GR-7 and massaging my scalp with it. That was a pretty nice unintended benefit! So, I will continue to use this. It's a little on the pricey side, but hey. There is the matter of the smell that some people complain about. It's really not bad at all. I made the mistake of telling my wife about a person I read about who quit using GR-7 due to his family complaining about the smell. I believe I predisposed my wife, and she gives me a hard time. To be honest, she would be giving me a hard time about something else, so it's built in. I believe, in part, she does not like her husband looking younger. And so it goes. My kids don't notice the smell at all, and they just roll their eyes when my wife complains. You can perceive a slight smell, nothing major, when you put it on, and for about 1 hour or so, but then the smell goes away once the hair dries. So, I recommend putting it on first thing in the AM. That way the smell will be gone, especially when yo go to sleep. Again, I am happy with this product. Very easy to apply, very good results.
