Ive started doing this with my beard recently. I'm amazed at how much better it works than actually washing my beard with warm/hot water. I fill up a container with cold water and mix in some raw apple cider vinegar (as a conditioner. Takes out tangles. Balances Ph level of the skin underneath the beard) and then dunk the beard in for 30 seconds. Its never looked so good! Ive been doing this for about 2 weeks now and will continue!!
