The awareness of the importance of appearance is becoming high and branches of beauty are becoming specialized in modern society. People have recently been more interested in nail art than any other branches of beauty. Among types of nail art, gel nail art is becoming the center of those. People's higher interest in gel nail art is causing frequent nail damage. The purpose of this study is to find out the effect of nail strengthener on the nail damaged from a gel polish procedure. A gel polish procedure was performed on 26 women with relatively undamaged nails in their 20s and 30s. After the procedure, a nail strengthener was applied onto their nails, and then the surface and thickness change of the nails were evaluated 1, 4, 7, 8, and 11 week following the procedure and treatment. A Scanning Electron Microscope (SEM) was used to measure the surface change and a Digital Calipers was used to measure the thickness change. Satisfaction of the procedure was also investigated. The result was that the surface damage figures for the group of the subjects who did not have the nail strengthener treatment increased (week 1 - 3.70, week 4 - 3.90, week 7 - 3.80, week 8 - 4.23, week 11 - 4.30) while the nail damage figures for the group of the subjects who had the nail strengthener treatment increased. (week 1 - 3.38, week 4 - 3.33, week 7 - 2.50, week8 - 2.82, week 11 - 1.92) The thickness figures for the group of the subjects who did not have the nail strengthener treatment decreased (week 1 - 0.31, week 4 - 0.26, week 7 - 0.27, week 8 -0.26, week 11 -0.24) while those for the group of the subjects who had the nail strengthener treatment increased. (week 1 - 0.32, week 4 -0.37, week 7 - 0.39, week 8 -0.37, week 11 -0.40) In a survey on satisfaction after the experiment, in terms of the degree of nail damage after the gel polish procedure the subjects who did not have the nail strengthener treatment thought 85.7% of their nail on average was damaged after the gel polish procedure while the subjects who had the nail strengthener treatment thought their nails were not damaged after the gel polish procedure. The subjects who had the nail strengthener treatment thought the treatment became effective for improving the state of their damaged nails in two weeks and all of them wanted to have a gel polish procedure with a nail strengthener treatment again in the future.
