1. Clean your lashes: make sure your lashes are free of any makeup, oils or debris.

2. Avoid caffeine: Refrain from consuming caffeine before your appointment, as it can cause your eyes to flutter, which making it challenging for the lash technician to apply the extensions.

3. Arrive make-up free: come to your appointment with no eye makeup on, including mascara and eyeliner, as this ensures a clean surface for the lash artist to work on.

4. Communicate your preferences : clearly communicate your desired lash look and concerns you may have with your lash artist before they start application process.

5. Schedule your day: plan your day before your appointment, as lash appointments may take up to couple of hours depends on the lash style you are getting, make sure you have enough time set aside.

By following these steps, you will be well-prepared for your lash appointment and ensure the best possible outcome.
