Question: what is number 1 haircut?
Answer: Haircut numbers refer to clipper guard sizes, and you can find the number etched into the guard itself. ... Similarly, a “Number 1 Haircut” is a very short cut that corresponds to a 1/8 inch length; a “Number 3 Haircut” cut to 3/8 inch; and a “Number 4” is the medium length of 1/2 inch.
