FAQ – frequently asked questions
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.
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.
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.
How long does a bottle last?
Can I use GR-7 on my beard?
GR-7 was primarily developed to be used on the scalp, but we had some of our clients use it on their beards and they were happy with the results. However, the safety and effectiveness studies conducted by Eurofins were conducted for the use of GR-7 on the scalp only, which is why we cannot recommend the use of GR-7 on the beard. If you would like to use it on your facial hair, we would recommend performing a patch test first, as the skin on the face is more sensitive.
