Which procedure is vital before starting an eyelash extension application?

The procedure that is essential before initiating an eyelash extension application is conducting a pre-application consultation with the client. This step allows the technician to gather crucial information regarding the client's preferences, eye shape, and specific needs. It creates an opportunity to discuss any potential allergies, sensitivities, or medical conditions that may affect the application process.

During this consultation, the technician can also explain the different styles and lengths available, ensuring that the client has realistic expectations and is well-informed about the process. Having this dialogue not only builds trust between the technician and client but also ensures that both parties are aligned on the outcome, enhancing customer satisfaction.

The other processes, such as conducting a patch test or selecting the types of lashes, are important but are typically secondary to the comprehensive understanding that comes from a thorough pre-application consultation. A patch test, while useful for identifying any potential allergies, may not be necessary for all clients and is often performed separately. Choosing lash types, while crucial for the desired aesthetic, follows after understanding the client’s preferences and needs from the consultation.
