You may be thinking why would I title my review "Great wash" and only give it four stars? Well, for my gray beard, it's way too stripping to use it daily.
When I use it, my beard is very squeaky clean. That tells me it's stripping everything off, including all the good oils, etc. that I've applied already, not just the dirt/pollen/etc on the surface. I will only be using this one about 1x/week when I need to strip everything off and start again. When I use it, I HAVE to follow up with a conditioner.
It's a great product, just too harsh for a daily wash, at least for me.
