During a pink and white overlay, what should a practitioner do if the white acrylic is clear and does not maintain its shape?

Applying a new bead is the appropriate action in this scenario because it allows the practitioner to correct the shape and structure of the overlay without starting from scratch. When the white acrylic is clear and lacks definition, it indicates that it might not have been applied effectively or has not set properly. By adding a new bead of white acrylic, the practitioner can reposition the product to create the desired shape and opacity.

This technique also helps to reinforce the structure of the overlay, ensuring it maintains its intended look and durability. Incorporating additional material strategically can lead to a more aesthetically pleasing and functional nail enhancement, allowing for proper shaping and better adherence to the natural nail.

The other options would not address the immediate need for correction as effectively. Sealing the acrylic with a top coat would not resolve the underlying shape issue. Continuing to shape the existing acrylic would likely not improve its clarity or structure. Removing the old acrylic entirely is a more drastic step and not necessary if the issue can be rectified with the addition of a new bead.
