Taking the previous style in its entirety, this look adds one simple
feature: a razor-cut ponytail. Now, it is as equally likely that the second style was the first creation and that the ponytail seen
here was simply removed to create the fully cropped look as it is that the ponytail you see here was grafted onto the hair as
extensions.
If it is, indeed, extensions, it is likely that the extensions are applied using the fusion method for a secure bond
to the shorter lengths. The hair is too short for the track and sew method and the area seems potentially too small for tape-on or glue-bonding methods.
