12. A client has arrived for a gel manicure. After nail preparation and applying the base coat, the technician notices that the client's hands are slightly damp from perspiration, despite wiping them down. What is the most crucial step the technician should take NEXT to ensure proper adhesion and longevity of the gel polish?
Nail Care and Services
A.Increase the UV/LED lamp curing time for the base coat to ensure it dries completely.
B.Apply an extra layer of base coat to create a stronger bond.
C.Use a dehydrator or nail cleanser to thoroughly remove moisture and oils.
D.Proceed with the color application, as the base coat will seal any remaining dampness.
Show answerAnswer
C. Use a dehydrator or nail cleanser to thoroughly remove moisture and oils.
Moisture and oils on the nail plate are primary causes of gel polish lifting and poor adhesion. A dehydrator or nail cleanser is specifically designed to remove these residues, ensuring a clean, dry surface for optimal gel application. Applying more base coat, ignoring the dampness, or simply increasing cure time will not address the underlying issue of surface contamination.
13. A cosmetologist is preparing to perform a chemical texture service on a client whose hair has been previously colored with a permanent hair color. What is the most critical pre-service test to perform to ensure the hair's integrity and prevent damage?
