Why is it important to apply primer before attaching nail tips?

Applying primer before attaching nail tips is essential because it enhances adhesion. Primer works to create a stronger bond between the natural nail and the artificial tip. This bond is crucial for ensuring that the nail tips stay securely in place during wear, which helps to prevent lifting or separation over time.

When primer is used, it prepares the natural nail by removing oils and moisture, which can interfere with how well the nail tip adheres. By creating a more receptive surface, the primer helps the adhesive or the gel used later to grip the nail tip more effectively. This step is fundamental to achieving a long-lasting and durable nail enhancement.

The other options do not relate to the primary function of primer in this context. Softening the nail and promoting growth are not relevant to the attachment of nail tips. Changing nail color does not pertain to the adhesion process either, as the primer's role is strictly to ensure a secure attachment rather than altering the appearance of the nails.
