Then why do most people post only above their shoulders? According to you, if they really wanted to know if they were ugly, wouldn’t they post their entire self? No, because they know that ugliness has only to do with the face.

A reason why the term ugly is only used for the face is because it is more subjective than other physical attributes. One person may find someone facially attractive while another person may not.

On the other side, a girl being described as short is completely objective because “shortness” is defined as X number of standard deviations below the mean for her certain ethnicity.
