Junction

For a perfect realization of your hairstyle, the plate obligatorily will be joined to dimensioned and the nape of the neck.

No place one will have abrupt difference in length.

The junctions will be often square at the men, rounder at the women, but at any time there will be break.

NB: Some very structured cuts tolerate "not-junctions", in particular the squares with shaven napes of the neck, but in this case, this "not-junction" is voluntarily accentuated.
