How long does it take to see results?

The listing says visible black results come in minutes per wash. In practice shampoo dyes usually deepen over several uses, so expect a gradual build rather than a single dramatic change.

Will it cover gray completely?

It is designed to cover gray, light and faded hair. Coverage on resistant gray often takes repeated washes, and results vary by hair porosity.

Can I use it on my beard?

Yes. It is made for both scalp hair and beards, which is why it is sold as a hair and beard color cleanser.

Yes, the formula is ammonia-free and paraben-free, and it contains keratin. It is still a dye product, so patch-test before first use.

How long will a 500ml bottle last?

That depends on how often you wash and how much color you need. Used a few times a week on hair and beard, a 500ml bottle should last weeks to a couple of months.
