When should a dehydrating product be applied to the nail?

• A. After applying the nail form
• B. Before applying the nail form
• C. After applying primer
• D. During filing

Answer: (B)

Dehydrating products prep the nail by removing surface oils and moisture, creating a clean, dry surface for a strong bond. Using the dehydrator before placing the nail form ensures the natural nail surface is ready to bond directly with the form and subsequent product. If the form goes on first, moisture trapped under the form can weaken adhesion and lead to lifting later. This step is part of the initial prep and isn’t done after primer or during filing, because those stages rely on already dry, clean surface for optimal bonding.
