I am 69 years old. My eyelashes are still very blonde, as are my eyebrows. Do they 'match' my Redhair, not really but they do blend. I don't believe our eyelashes change color as we age. And I'm dubious about eyebrows changing colors, too. I have seen many a man with graying hair and their eyebrows are still the color their hair used to be. It is possible that a very old gent's eyebrows may start to grow white or gray in time. My hubby's are still brown, his beard is mostly white, now. With very little change to the hair on his head. Just my observation. Take it or leave it.
