gr-7 uk no more grey hair 1
1.Will GR-7 Professional work on dyed hair?

GR-7 Professional restores the natural colour to hair that has gone grey, which is why it will not work on dyed hair. We recommend having at least a 2 cm growth of natural hair before starting the treatment to see the effects. 

2.How will I know if I am not allergic to it?

GR-7 is a safe product, but as any cosmetic in some cases an allergic reaction may occur, which is why we recommend performing a patch test on your skin 24h before using it to avoid potential side effects.

3.How long will it take for GR-7 to work?

The first effects of the treatment should be visible within the first 7 days. The speed of regaining your natural hair colour depends on various factors, such as the amount of grey hair, lifestyle, age and cause of greying. Overall, it takes anywhere from 14-21 days to fully regain your natural hair colour. It is also crucial to be systematic and closely follow the directions for use.

4. Can I get a discount on my first order to try it?

Yes, if you want to try GR-7 you can use the code generator available on our website to get 30% off your first bottle. (Works for single bottle orders only). Sign up for the discount!

5.Once I regain my hair colour do I have to keep using GR-7?

Once your natural hair colour is fully regained after the initial treatment we recommend using GR-7 once a week to maintain the effect. More information can be found here.

6.I would like to start the treatment but I still want to wash my hair. How will that influence the effects?

Washing your hair during treatment will slow the process down. We recommend not washing your hair for at least 3-4 days to a week, after you first start using GR-7 for best effects. More information on the application can be found here.

7.My hair has turned a little yellow at the beginning of the treatment. Is it a bad sign?

Not at all, it’s a natural process! In the first stage of the treatment, your hair will be gradually darkening. It might initially change to what can be described as a “yellow-ish” colour, but do not worry, it is part of the process and only lasts for a few days. 

8.How long does a bottle last?
One GR-7 bottle is normally enough to go through the entire first stage of the treatment, so to fully regain the natural colour. To maintain the effect you will only need to use a little bit once a week, which makes the bottle last much longer.
