One fo the best products for men who like to keep beard and need to cover the grey hair.. amazingly easy to use.. the beard gets coloured in less than 10 minutes of time.. very economical, as the packet comes with 6 pouches.. so you can use it once every week.
Does not stain the skin at all. That's the best part !!!
