Well, I looked at your profile again, hoping to see "examples", LOL.
No freshly dyed beard pics there, right?

I have dyed mine a few times, because it tends to have sooo many colors in it, LOL....it really does have pretty much almost every natural hair color you can have, other than super-light blond. That is just too "busy" for my fag tastes, visually speaking. So I've dyed it closer to all one color , a few times in the past. Black. Dark brown. Medium brown.
It's o-kayyy (*shrugs*) dyed, but to me, it still looks "artificial", even if you know something about the "right" way to dye hair...which I do. I think it could look good if a person took way more time with the proces than I do, or maybe, LOL, if their beard was more "normally colored" in the first place, and didn't have 9 different colors. I think I notice the change more than other people would, because to me it's like "uhh, now I have one color here---- ten minutes ago it didn't look anything like that".

If you decide to dye it blond, be careful---- you will have to bleach the hell out of it first, and that can be tough on your skin. But if you bleach it, you then aren't tied to "natural" colors---- and can have a nice burgandy or green or purple or all of the above beard.
;)

One thing, as hairdresser I know this, it's the art of dyeing, unless you mean to expire while tinting your beard...
Yeah, I dye mine all the time. My once black hair and beard are gone quite grey now, and I'm only 40. I usually use a semi-permanent color, which has no ammonia or peroxide, so I don't get any weird orange tone. I also go a few shades lighter brown than I used to be, so the grey hairs pick up some color, but it doesn't look so harsh when it starts to grow in again. I tried once or twice to go really dark, like I'd been in my youth, but I just looked like a bad Elvis impersonator. I like keeping some grey in it- stripes, if you will- that I grow longer and trim it all into a sort of "Swallow's Tail" look.
