I've had beards of varying lengths for years and during that time, I've had flareups of beard dandruff, or what's commonly referred to as beardruff. It usually starts out with some itching and then, after a while, I notice that my face skin that's under the beard turns red and inflamed. It's pretty terrible. I've tried washing my beard well, but that doesn't do anything. After a while, the flakes begin and it's like I've got dandruff falling out of my beard all day. I once scratched my beard for a minute or so over my lap and it looked like it snowed. I can't believe how much dead skin came out of it. It was so gross. So my question is, how do I get rid of my beard dandruff (beardruff)? Is there anything I can do at home, such as a home remedy? Or do I need to see a doctor or get some special shampoo?
