Input (English): [header] How to razor cut your own hair [title] Purchase a razor comb and razors. [step] A razor comb is typically divided into three sections. The end of the comb contains a regular comb. <sep> (A) The front of the comb is divided into two different sides: the small-toothed side and the wide-toothed side. The wide-toothed side can be used to create choppy layers. (B) [substeps] The comb's steel lock has two looped ends and the other end contains a nylon-toothed lock. The nylon-toothed locks the razor directly from the comb's teeth. (C) You will need to use it each time you cut your hair. They measure 1 to 2 inches (2.5 to 5.1 cm). (D) This is important because if you don't cut a long section of hair, it will create more hair that will start to irritate your skin. Also, a comb can injure your skin by pulling your hair apart and irritating the skin.
