How should metrology be conducted before a nail service?

Conducting metrology before a nail service involves assessing the natural nail for length and shape preferences. This step is crucial as it helps the nail technician understand the client's desired outcome based on their individual style and the natural characteristics of their nails. By evaluating the natural nail, the technician can provide recommendations that align with the client's preferences while ensuring the health and integrity of the nails are maintained.

Assessing the length and shape preferences also allows for a customized approach to the service, ensuring that the final result enhances the client’s hand and overall appearance. This understanding is foundational before moving forward with any type of nail enhancements or services.

While measuring the client's finger size, observing nail health, and discussing color preferences are relevant to the nail service, they do not specifically address the direct assessment of the natural nail, which is a key component in metrology for achieving the best and most satisfying results for the client.
