Clipper Cuts & Length Guards

A: Well, yes and no. The term "Number 2 haircut" refers to a clipper cut given using the #2 length guard on the clippers. This cuts the hair to a uniform 1/4-inch or six millimeters length. So, while your hairdresser would cut your hair very short - perhaps shorter than you might have expected - your head wouldn't be completely shaved, nor would it be as short as some clipper cuts can be.
These length guards are numbered, and each number corresponds to a specific length. There may be slight variation in the exact length of a guard across different brands, but they are generally standardized. This makes it possible for a person who usually keeps his or her hair very short to go to a barber in a new town and say "I want a #2 (or whichever) cut" and end up with something at least very close to what he or she normally wears.

• #1 - one-eighth of an inch or three millimeters
• #2 - one-quarter of an inch or six millimeters
• #3 - three-eighths of an inch or ten millimeters
• #4 - one-half of an inch or thirteen millimeters
• #5 - five-eighths of an inch or sixteen millimeters
• #6 - three-quarters of an inch or nineteen millimeters
• #7 - seven-eighths of an inch or twenty-two millimeters
• #8 - one inch or twenty-five millimeters
Below is a comparison chart for the clipper guard lengths (also known as cutting guides, guide combs, or guide attachments) of five popular brands for clippers: Andis, BaBylissPRO, Oster, Remington, and Wahl. As you can see, there is little to no difference between the brands.

There has been a resurgence in the popularity of super short buzz cuts. This low-maintenance haircut has captivated the hearts of both men and women, who appreciate the unparalleled convenience it offers. Gone are the days of spending hours styling and blow-drying. With a buzz cut, a simple towel dry after a shower is all it takes to be ready to go.
One of the remarkable aspects of these ultra-short cuts is how they complement individuals with thinning hair. By keeping the hair extremely short, the focus shifts from the quantity of hair to the person's features, resulting in a bold and confident look.
