GR-7 Professional

Very bad, after 2 months the product did not arrive. I even paid customs. In the other hand, my friend bought the product and did not work. In summary, I have seriou doubts and concerns about logistics and efficacy

I've been using this product over the 3 weeks and it just doesn't work. I still have the grey hair and my scalp is more dry now than before. Be careful with this product 😞

I'm very happy with product. Start see difference in about 2 weeks, after 3 weeks almost all grey hairs gone.

I've been using this for about a month now and I can say it does work. I have had a lot of grey hair over the years primarily due to stress, but since using it, they've become less obvious. I'm hoping that with time and frequent application, GR-7 completely restores my hair back to normal. But from my short experience, I'd recommend it.

I am very happy, it works, at the beginning I had some hair left on my hands, but the gray hair is gone, and I must say that I was smoking cigarettes and drinking strong coffee normally. I wish I had taken pictures of my hair before and now after 21 days, and I used GR7 once a day and washed my head every 4-5 days. I recommend it, it worked for me. My natural color come back 😉

I would deffinatly recommend gr7 to anyone who has grey hair.I have been using this product now since the beginning of lock down and it certainly has got rid of my silver/grey roots.I now have my natural medium brown shade back.Im very impressed and will continue to use.It saves me lots of money going to the hairdressers to gave my hair coloured.Big thanks to gr7

Satisfied with this preparation, it works. Hair regains its color. I didn't have any side effects while using it

After some 4 days , hair started to turn yellowish, which scared me a bit, but that was the sign of change. Now hair is back to normal colour - 95%.

Quick delivery. Great product. It works but takes a bit of effort for the first few weeks. Once it is working its simple to use and much better for my hair than hair dye.

This does absolutely work yes.Its not an overnight fix,so if you want that,forget this and buy some Just For Men or similar. I used it twice a day for three weeks,which was,for me,one bottle.It gives you your own natural colour back,but as iv said,you have to be consistent and patient.It does what it says on the tin!

Amazing product. It works! Hair lost 90% of grey.

It hasn’t worked for me yet and Iv used it for 8 days now but can see a bit off progress just waiting for results, since this review above I’m starting to see results

After developing an allergy for hair dye I looked for alternatives to cover my gray hairs. I found GR-7. I was a little sceptical in the beginning, but it really works! No more gray hairs and no allergic reactions.

Effective product, but it needs time to see the expected results, more than 21 days.

Good product

Effective product

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.
