I have been using often and colour returns to hair, grey disappears, stopped going to hairdressers to get hair coloured and hair seems thicker too.
Very good product and it does what it promise
gr7 does work the greys are disappearing and it’s certainly doing wonders🙂
For a long time I was tired of constantly dyeing my hair and growing roots, then I started looking for products that would somehow hide my gray hair. The dream was that they would eliminate them, but who believes in dreams today;) When searching for products, I was focused on something a bit more expensive but effective. After using GR7, according to the instructions from the leaflet, after a few days my gray hair started to lose and its color changed to a beautiful natural light brown, which, combined with the paint peeling in the area, creates a great ombre effect. I am very pleased with the colour and the possibility of quick use at home. Now I go to the hairdresser just for nice cuts. However, I would like the bottle to last longer. But what matters is the effect, and for it it's worth it.

Used it for a month twice a day no change to hair colour
GR-7 took a while to be effective, but finally worked for me. The customer service I got was caring, friendly and knowledgeable. The bottle arrived in 2 days and after two to three weeks, carefully observing the instructions most of my original colour has returned. This is really amazing and far better than dye (and grecian 2000)
My first concern was about not washing my hair for the first week of using this product. I thought it would be gross. Actually it wasn't that bad as somehow the product seemed to keep my hair somewhat clean each day. I'm on my second bottle now and I definitely noticed my greys getting back colour. They go a light brown/Amber first, then start getting darker each week. My natural colour is black so I'm going to keep trying it to see if I can get them all black again
I originally have dark brown hair, which is 60-70% already grey, and I think I have a lot more hair than average. The bottle is 125ml, so when I got it, I was a little bit disappointed because it seemed to me that one bottle would be enough for 1 week (in my case). I used it twice a day, the results started to show relatively slowly, but after 4 weeks and using the fourth bottle I am quite satisfied with it. I think the result also depends on the type of your skin, I almost completely regained my dark brown colour on the sides, but there are still greyish, blondish, brownish shades on top of my head. Surely everyone gets the result differently, so I say that whoever decides to start using it should be persistent and do it all the way through.
Was a bit skeptical of this product. I am only starting to get the odd grey hair so was not quite ready for dyeing my hair. But this seems to work. My odd grey hair is disappearing. Definitely would recommend. Only reason why I would not give it a 5 is this product is quite hard to put on and end up loosing a lot of product trying to put it on with your hands. I think that is one thing they could improve. A better way to get the product onto your scalp. I think a spray bottle personally would be better.
Seems to be working but slowly I think it will take at least 3 bottles= 3 months I’m happy to buy more and carry on using it also I had 95% grey when I started so I guess it also depends on the level of greying you have
It’s been a week now since I applied this product. I have 90% greys and used to colour twice a month. My original hair colour is dark almost black so when greys come through it’s very noticeable. To apply this product I had to grow my greys a little. I grew my greys about 2cm. I haven’t regained whole colour yet (as I said it’s just 7 days so far), but my greys started blended in which is amazing! I am looking forward to keeping applying this product and restoring my colours entirely. No harsh damage to your hair and scalp like hair colour with chemicals cause. I actually have less hair loss and scalp doesn’t get irritated these days. Good sign! Great product.
Best hair I had in a long time well happy 😁👊
