I believe thiis is just due to genetics, perhaps, thin
eyelashes are genetic as well... and one side being
longer than the other could be considered normal. After all, I have been told that hair tends to grow faster on one side than other. If this is so, why can't eyelashes? And I agree with Dr. Hagan, that this is related to anxiety. To my knowledge there is no cure for this. I've tried everything!
