What is a nail dehydration step and why is it important?

• A. Applying a light moisturizer to nails prior to dehydration.
• B. Removing surface moisture and oils to improve adhesion of enhancements.
• C. Polishing nails to a shine.
• D. Buffing cuticle.

Answer: (B)

A nail dehydration step is the process of removing surface moisture and oils from the nail plate so the adhesive can bond properly. This creates a clean, dry surface, allowing the bonding agent to grip the nail rather than sit on a slick layer of moisture or oils. When dehydration is done well, it helps the enhancements adhere firmly and reduces lifting and early failure.

Moisturizing would leave oils on the surface, which undermines adhesion. Polishing nails to a shine focuses on appearance and smoothness but doesn’t reliably remove moisture or oils from the nail surface. Buffing the cuticle tackles the cuticle area and isn’t the step used to prepare the nail plate for bonding.
