A buzz cut (sometimes known as a wiffle or crew cut) is the American name for a type of haircut named after the sound of the electric razor, which is used to shear the hair very closely to the scalp. In the United Kingdom, the haircut is called a skinhead (although the skinhead hairstyle was originally called a skiffle). In the Philippines it's called semi, for semi-kalbo (bald), among Tagalogs or skinhead among Visayans. In Singapore it is often called a "GI (number)", with the number representing the seven different grades. In Australia the haircut is usually called a "crewcut".
It is one of the most rapid haircuts possible, and can take little more than a minute to cut when done with good quality clippers. Buzz cuts come in seven grades: #0 or bareblade (shortest), #1 (3 mm), #2 (6 mm), #3 (9 mm), #4 (12 mm), #5 (15 mm) and #6 (19 mm). These numbers correspond to eighths of an inch.
A buzz cut makes the face look more defined, and the jaw wider. The buzz cut is popular among men and women who want a short, low-maintenance hairstyle. A buzz cut is worn by some men to conceal thinning hair. Fewer women than men get their hair clipped off. In some countries, armed forces recruits are given buzz cuts when they enter training. The buzz cut has been popular in hip hop culture since the 1990s. In hip hop circles, the head is often covered by a bandana, do-rag or baseball cap. This hairstyle is contrary to common styles in previous decades, when it was more popular to grow and style one's hair.
There are many different variations of buzzcuts. One variation leaves some bangs so they can be spiked upwards using gel or other hair products. With side fades, the side hair slowly fades shorter and shorter until the hairline ends, or the shortest clipper number is reached.
