To treat a kind of nail damage, this study proceeded with gel polish procedure oriented to 19 women in their twenties and thirties, dividing into three experimental groups, such as the A group with non-treatment (n=6), the B group taking Nutritional Convergent supplement (n=6), and the C group simultaneously taking Nutritional Convergent supplement and Nail Convergent Strengthener (n=7), and inquired into the superficial change of nails, changes of thickness, analysis of damage degree and satisfaction rate. The analysis shows that the C group simultaneously applied with dietary supplement and complex nail supplement presented the best result in all areas. As for the morphological changes of the surface of nails measured by the scanning electron microscope, there were definite changes as compared with the B group. According to the result, it is proved that complex dietary supplement helps to improve the thickness and the surface of damaged nails and it is reasoned that a higher effect can be expected when complex nail supplement is simultaneously used.

As the nail industry has grown, concerns on damages to natural nails due to nail services and interests on nail products have been increased. This study is on nail convergent strengtheners which reduce damages on natural nails, and especially focused on the use and awareness of nail strengtheners by nail technicians. First, documentary research on previous studies was conducted to define nail services, nail damages, and nail strengtheners. Preliminary survey and main survey was conducted by KSDC on-line survey tool and the result was analyzed by frequency analysis, cross analysis, and correlation analysis by KSDC advanced statistical program. As a result, nail technicians have the high level of awareness on characteristics, effects, how to use, and application process of nail strengtheners. Nail technicians are the mid level of awareness on the ingredients of nail strengtheners.
