What does the end paper technique in perming ensure?

The end paper technique in perming is essential for ensuring that the perm solution is evenly distributed throughout the hair. By using end papers, stylists can control how the hair wraps around the perm rod and help prevent any inconsistencies in the curl formation. This technique allows for a smoother application of the perm solution, leading to a more uniform curl pattern and reducing the likelihood of uneven or patchy results.

The technique also helps to secure the ends of the hair during the rolling process, which is critical for achieving the desired curl shape and definition. This method is pivotal in providing a consistent base for the chemical reaction that will alter the hair's structure, leading to a successful perm.
