I had a full mixture of brown, red, gray and white facial hair.
Because so much of it was gray and white, I "assumed" that electrolysis was my only path.
After having invested a lot of time in electrolysis, a comment from a dermatologist on an unrelated visit prompted me to look into laser again.
So I did and have had 5 laser treatments since July. I still have some white and gray hairs that only the electro will remove, but the laser removed virtually ALL of the dark hair making my face at least appear much clearer. And did so much faster than electro would have done. There is NO evidence of beard shadow any more, but after a couple of days there is still rough stubble.
I give at least a week off of electro before a laser session and a week after and it has worked well for me.
