Sigh. This picture managed to get itself tagged with both short_hair and long_hair. It can't be both, people.

My personal opinion is that short_hair doesn't apply once its past chin-length or so, but if we actually have guidelines about this, do let me know.

In general the dividing line between hair lengths is pretty gray. There has been at least one thread about this, but in the end I don't believe it went anywhere. The problem is how people define their hair length. Some people for the most part only have 2 divisions for female hair, while others have 3 or even 4 divisions of hair length.

For me I wouldn't consider this either short hair or long hair.

The only hair length that has a length definition is very_long_hair.

If the hair does not visibly reach beyond the shoulders, then it is not long.
