My guess is the length of the beard makes a lot of differences. I think previous studies have shown long stubble to short-cropped beards doing best with the ladies.
Ha, I “tried” growing a beard twice, years apart while injured and unable to easily shave, and long enough for it to grow out a few inches.
It was thin, curly hair, that seemed to need to be combed all the time and looked silly, especially with the two bald patches where dimples would be if I had them.
Most of the male Hallmark main characters seem to have the 7 pm shadow thing going, mostly with makeup.
