Research Paper : A Comparative Experiment of Nail Damage According to Removal Methods

Eun Young Shin, Jeoung Min Lee

Abstract

Artificial nails should be removed from the natural ones after a certain period of time. It is during the removal process that the natural nails, which once had artificial ones attached to them, go through physical and chemical changes. Under the goal of investigating nail damage according to removal methods, this study compared two types of nails of the same company in the domestic nail market for changes to the nail shape and nail damage according to removal methods. The products were gel nails that could be removed through filing and the ones through a special solution or acetone. A group of women, who showed no special problems with their health, maintained a relatively good state of health, and were 25 or 28, was convenience sampled. Total six subjects were chosen who included three that were 25 and another three were 28. Both the age groups received no nail treatment for the last two months. The subjects were given a number from A to F. Before the experiment, their nails were measured in thickness. The middle finger thickness that was the closest to the mean was chosen as the experiment sample. Before treating the gel nails, the free edge of the nail was cut by 2 mm to measure its condition. Since there is no widely accepted method to measure nail damage, the investigator made the natural nails before attaching artificial ones the control group and did four treatments of artificial nails on the same nails every two weeks for eight weeks. The experiment group included the gathered sample nails. A multilateral experimental analysis was carried out in shape changes, strength, and thickness to understand the influences on the structural changes of the natural nails.
