Improper nail preparation is a leading cause of most types of nail enhancement product ____.

Improper nail preparation is a critical factor that leads to lifting of nail enhancement products. Lifting occurs when the product does not properly adhere to the natural nail surface, creating a gap between the enhancement and the nail. This can happen if the nail is not adequately cleaned, filed, or dried before product application.

Good nail preparation involves ensuring that the natural nail is free from oil, moisture, and debris, which allows for optimal bonding of the enhancement product. If this step is neglected, it compromises the integrity of the bond, leading to the product lifting away from the nail. Proper nail prep techniques are essential for achieving a long-lasting and aesthetically pleasing manicure, emphasizing the importance of this practice in the nail care process.

Other options, while they may be related to nail enhancements, do not directly connect to the concept of improper preparation as strongly as lifting does. Discoloration can result from factors like the ingredients in the enhancement product or staining from external substances. Allergies are more often caused by sensitivities to chemicals rather than preparation methods. Cracking can occur due to factors such as product formulation flaws or excessive stress on the nails, but again, pulling back to preparation leads to lifting as the primary issue when integrity is compromised.
