Final answer:
After dividing the hair into sections, a hairstylist begins by establishing a guideline for the desired length and then cuts the hair in successive sections, maintaining consistency in angle and elevation while checking for symmetry and blend.
Step-by-step explanation:
After dividing the hair into sections in haircutting, you should begin cutting the hair. Typically, you start by selecting one of the sections as your guideline—the section where the first cut is made to indicate the intended length of the haircut. Once you have established this initial guideline, you should proceed by cutting the hair in the next section, following the guideline to ensure even length throughout. Be sure to comb the hair smoothly and hold it at the correct tension between your fingers or with a clip before cutting. Consistency in the angle and elevation at which you hold the hair is crucial for maintaining the desired shape and length of the cut. Repeat the process, checking the symmetry and blend between sections, until you have worked through all the hair sections and completed the desired style.
