Nails are continuously damaged and injured during our lifetime. Recently artificial nail art procedures can give severe damage to the natural nail. Thus, nail guard (also called nail strengthener/hardener) should be used to protect the nail from any artificial nail treatments. Experiments were intended to study the effect of nail guards products on the surface and cut section of the damaged nail.1) Three cosmetical nail guards products were selected considering the price, ease of operation and popularity. The group members applied the nail guard
everyday to the damaged nail for two weeks. The morphological changes of nail surface and a cutting plane were monitored and analyzed using scanning electron microscope (SEM). Many side effects of nail art treatment have been confirmed by the morphological change and questionnaire survey. The damaged portion of the upper part is more severe than that of the lower part. The lamella structure of the damaged nail showed the serious crack. The nail guards
products gave a temporal strengthening effect to the damaged nail. Among the ingredients of the nail guards products, the protein and moisturizing components are considered to be participated in the hardening of the nail.
