Hey guys.
So, my brother (in his early thirties) is feeling quite insecure these days about the white hair in his beard. It bothers him a lot and although I've been encouraging him to embrace it and go for the silverfox look, he's not so adamant.
Anyways, he's been looking for long-lasting products that will dye his beard, he's tried those mascara-like products and the beard powders too, all of them wash off with water/sweat. I just wanted to ask men in general what products would you recommend? Is there any good dye which would last, because beard grows in like 2-3 days, right? Maybe some sort of salon treatment or other sort of product that would be helpful and long-lasting?
Thank you
Would really appreciate any help that I can get.
