Induction cut

An induction cut is the shortest possible hairstyle without shaving the head with a razor. The style is so named as it is traditionally the first haircut given to new male recruits during initial entry into many of the world's armed forces.

Some Army drill sergeants have referred to this cut as the "Mighty Fine." Other names for this haircut are a "buzz cut" or a "number zero", "on the floor" and "the Army's #1 haircut".

The term buzzcut is used to generically describe all hairstyles where the hair is cut short to a consistent length all over using clippers. The induction cut is distinguishable by the clippers being used without any guard or attachment, resulting in the shortest possible cut. The scalp is not shaved with a razor, but only very short stubble is left. Some people may refer to this haircut as a number 0.

As with many other short hairstyles, including a shaved head, the induction cut is becoming increasingly popular as an everyday hairstyle. It is one of the hairstyles that balding men often choose.

In the French Foreign Legion (Légion Étrangère), this form of haircut, used by all recruits and many légionnaires is termed 'boule á zéro' (zero ball). In recent years, the U.S. military style of high and tight has also become popular in the Légion.
