A short hair half updo is a hairstyle that involves lifting the top half of short hair away from the nape of the neck and securing it at the crown, leaving some of the hair down. A common example is the "half ponytail" where the top half is tied with an elastic.
The short hair half updo is a popular hairstyle because it is easy to do, versatile, and can be dressed up or down. It is also a good way to get hair out of the face without having to tie it all up. The style has been around for centuries, with depictions of women wearing it in ancient Greece and Rome.
