How does it work?

Inactive melanin
Hair follicles contain melanin, which is responsible for the colour of your hair.

Why is melanin not active?
Age, stress, addictives, your genes – they all can make melanin in your hair bulbs less effective.

Here comes GR-7
It kicks melanin back into action. Naturally. You just need to let GR-7 reach your hair bulbs and do its job.

Give it some time
Two to three weeks is when most people will see their hair colour change back to natural.
Your natural colour in four simple steps

Apply to the scalp twice a day, in the morning and before bed

Rub it in evenly and thoroughly onto your scalp

Avoid washing or wetting your hair for the first few days

Repeat the treatment until your natural color is restored
