Background  About 90% of women worldwide use nail care products, including manicure ones. A manicure procedure results in nail damage, therefore it is necessary to search for new, objective methods of assessing the impact of the procedures and products applied within the nail plate. In this study, an attempt was made to quantify the impact of manicure procedures on the nail plate condition.    Materials and methods  Twenty thumb nail plates were examined. Before the manicure procedures, alginate casts were prepared for each of the subjects. The analysis of the three‐dimensional (3D) nail surface structure included the assessment of the nail sections and the assessment of differences in the nail structure after superposition of 3D images of the nail plates before and after the manicure procedures.    Results  The obtained results show that the nail plate structure changed to a similar extent in each measured section after the manicure procedure. A change in the height of the nails is not a desirable phenomenon as it suggests damage to the nail caused by the substances included in the preparations applied to the nails, acetone, or filing the nail plate. This proves the great influence of the technique of removing artificial nails on the structure of the natural plate.    Conclusion  The use of a 3D scanner allows for precise, biometric, quantitative, and repeatable measurements of changes in the nail structure after a manicure procedure. The use of the hybrid and gel manicure procedure causes significant damage to the nail plate, especially in its distal portion.
