Final answer:
Sanitizing a client's nails is crucial to prevent infections, ensure proper adhesion, and remove oils and debris, which are essential for the longevity and safety of sculptured nail applications.
Step-by-step explanation:
It is important to sanitize a client's nails before applying sculptured nails to prevent the risk of infections due to bacteria, fungi, and viruses that can readily grow in the warm, moist environment underneath the nail enhancements. Proper sanitization ensures that any potential pathogens are eradicated, thereby providing a clean and safe starting point for the nail application. Additionally, this step aids in the adhesion of the sculptured nails as oils and debris are removed, which might otherwise lead to lifting or the failure of the nail enhancements to properly adhere.
