How to Prepare for a Lash Extension Appointment
Simple steps to prepare for your lash extension appointment, so your set applies cleanly, feels comfortable, and lasts.
Reviewed by Son, Founder of Sonthuy Beauty
Whether this is your first lash extension appointment or you're returning for a new set, the way you prepare can help your lash artist work more cleanly, map your set more accurately, and give you a calmer experience.
At Sonthuy Beauty, lash extensions are applied with UV lash technology, but the basics still matter: clean lashes, clear communication, realistic expectations, and proper aftercare.
The short answer
Arrive with clean lashes, no mascara, no heavy eye makeup, and no oil-based products around the eyes. Give yourself enough time for the appointment, and be ready to lie still with your eyes closed while your lash artist maps, isolates, and applies your extensions. If you wear contacts, have sensitive eyes, or have had past reactions, let your lash artist know before the appointment.
Before your appointment
Arrive with clean lashes, free of mascara, eyeliner, eyeshadow, strip lash glue, oil-based makeup remover, and heavy skincare around the eyes. Avoid oil-based products around the eyes, and skip heavy eye makeup entirely, your lash artist needs clear access to your natural lashes.
- ★Arrive with clean lashes
- ★Avoid oil-based products around the eyes
- ★Skip heavy eye makeup
- ★Bring glasses if you wear them
- ★Mention contacts, sensitivities, or past reactions
Think about your lash goal
Before your appointment, it helps to think about the finish you want:
- ★Soft and natural
- ★More noticeable but still polished
- ★Fuller and more dramatic
- ★Lifted and eye-opening
- ★Everyday wearable
What to expect during the appointment
Your lash artist will look at your natural lashes, talk through your desired look, and choose a style that fits your eye shape. During the service, you'll lie down with your eyes closed while the artist maps, isolates, applies, and UV-cures your set.
What not to do before a lash appointment
- ★Wearing mascara
- ★Wearing heavy eyeliner or eyeshadow
- ★Using oily makeup remover before the appointment
- ★Applying heavy eye cream near the lash line
- ★Arriving rushed or late
- ★Booking if your eyes are actively irritated
Aftercare starts before you leave
A good lash appointment includes aftercare education. Before you leave, make sure you understand when and how to cleanse your lashes, what products to avoid, how often fills are recommended, how to brush your lashes gently, and why picking, pulling, or rubbing can affect retention.
Lash extensions are a partnership between the artist's application and the client's daily care. Retention still depends on your natural lash cycle, aftercare, lifestyle, oil exposure, skin products, sleeping habits, and fill timing.
Common questions.
Should I wash my lashes before a lash extension appointment?
Yes. Arriving with clean lashes and no mascara helps your lash artist work more cleanly and see your natural lashes clearly.
Can I wear contacts during a lash extension appointment?
Some clients prefer to remove contacts during the service. If you wear contacts or have sensitive eyes, bring your glasses or contact case and mention it before the appointment.
How long does a lash extension appointment take?
Timing depends on the set and whether you're booking a full set or fill. A full set usually takes longer because the artist is mapping and applying a complete lash design.
Does Sonthuy use UV lash technology?
Yes. Sonthuy Beauty applies lash extensions with UV lash technology. UV refers to the adhesive curing method, while "Lash Extensions" remains the service name.
