The Nail Integrity Method: A Nail Plate Assessment Protocol and Comparative Testing of Base Gel Flexibility and Acidity
Year: 2026
Type: article
Abstract: Gel nail services are often performed with one standard base and preparation routine for every client, although natural nail plates differ in moisture behavior, thickness, and flexibility, and commercial base gels differ in cured flexibility and acidity in ways their labels do not reveal. This paper describes the Nail Integrity Method, a protocol developed by the author in professional practice and teaching, and reports preliminary comparative tests of commercial base gels. The method separates nail plate type (dry, normal, or moist), current condition, and the final assessment, which ends in one of three decisions: proceed, modify the service, or postpone and refer. Type is recognized from practical observations, including whitening of the periungual skin under the dehydrating cleanser, rapid return of surface moisture, e-file clogging, and a history of pinpoint micro-lifting. Base gels are classified on three independent axes (cured flexibility, consistency, and acidity) using a standardized bending test and a two-stage acidity assessment: ingredient analysis followed by a comparative indicator test of aqueous samples. In twelve commercial bases, indicator results ranged from approximately 2–3 to 6, and three products fell below the method’s working limit; one product marketed for oily nails and extreme lifting read near 6, showing that adhesion cannot be inferred from acidic response alone. For each plate type the method specifies base acidity and flexibility, the preparation sequence, auxiliary liquids, structural gel properties, and layer placement, with the lowest sufficient level of adhesion as the governing principle. The method has not yet been evaluated in a controlled study; directions for evaluation are proposed.
