Final answer:
During the procedure phase of hair design, it is necessary to distribute hair in the desired directions to ensure a consistent and intentional style.
Step-by-step explanation:
The necessary action during the procedure phase of the hair design is A. Distribute hair in desired directions. This step involves arranging the hair to create the intended style or pattern. It is a crucial part of achieving the final hair design, which requires precision and attention to detail to ensure that the results are as desired. Distributing hair in random or over-directed directions will not give the consistency and pattern necessary for a polished look, and therefore, options B and C are not appropriate actions for this stage of hair designing.
