Why might a client experience a sensation after primer is applied?

When primer is applied excessively, it can lead to a heightened sensation on the client's nail. Primers are designed to help enhance adhesion between the natural nail and artificial enhancements, but if applied in larger amounts than necessary, they can cause irritation or a tingling feeling. This is particularly relevant if the primer contains acidic components, which serve to dehydrate the nail surface and increase bonding.

In contrast, other factors such as moisture on the nail can often reduce the effectiveness of the primer rather than cause a sensation. Allergies to primer ingredients may lead to discomfort, but the sensation might be more related to a specific reaction rather than just the application of the primer itself. Incorrect application techniques could lead to a range of issues, but excessive application specifically focuses on the application amount rather than the method of application. Therefore, excessive application directly correlates with the client's experience of sensation after primer use.
