1. Number 0: 1/16 inch or 1.5mm
The number 0 in terms of haircuts and clipper sizes refers to a very short length of hair. It is equivalent to 1/16 inch or 1.5mm in length.
This particular clipper size is commonly used for buzz cuts or to create a very close shave. The number 0 guard or attachment is often used by individuals who prefer a clean, low-maintenance hairstyle.
It provides a nearly bald look, with very minimal hair remaining on the scalp. The number 0 haircut is also popular among men who want to showcase a well-defined hairline or highlight facial features.
However, it is important to note that using a number 0 clipper size requires precision and careful handling to achieve the desired outcome.
