Re-balancing a nail during a fill-in service involves blending which areas?

• A. Old product to new growth area
• B. New product to old growth area
• C. Natural nail to cuticle
• D. Product to tip

Answer: (A)

Re-balancing during a fill-in focuses on feathering the boundary where the natural nail has grown out into the existing product, blending the old product toward the new growth area. This creates a smooth transition, restores even thickness, and helps prevent lifting at the growth line. The described approach—merging the old product into the new growth area—best captures this idea. The other scenarios don’t describe smoothing the boundary between the existing product and the natural growth, such as applying new product toward the old growth, prepping the natural nail at the cuticle, or laying product toward the tip.
