You mean it looks like a thick caterpillar crawling above your eyes. That's called unibrow.
When you get a hair cut you can ask them to cut an aisle between them. Instead my brother just shaves them off - NOT a good look for anyone.
As people tend to get older(men and women) usually the brows thin out and disappear at the far ends. Mine did that a million years ago. I know you can fill in with eyebrow pencil but, it generally wipes off or runs off and you've got one long brow and one skimpy one.
I just ignore them.
I did read a few times that it meant thyroid trouble but, I've been tested several times over the past few years and it's always normal . I fail to believe that one "normal" range covers millions of people - bah humbug!!
