Mastering Eyelash Infill Appointments: A Beginner Lash Artist’s Guide

As a beginner lash artist, mastering infill appointments is essential for retaining clients and ensuring their eyelash extensions look flawless between full sets. Infills aren’t just about adding more eyelash extensions - they’re about refining, correcting, and maintaining the integrity of the lash set. Understanding when and how to perform an eyelash infill properly will set you apart as a professional and keep your clients coming back.

What Is a Lash Infill and Why Is It Important?

Eyelash extensions are semi-permanent, meaning they naturally shed along with the client’s natural lashes. Since each lash is on its own growth cycle, some extensions will fall out sooner than others, creating gaps. An infill appointment is designed to replace these lost lashes, remove overgrown eyelash extensions, and refresh the overall look.

Why Lash Infills Matter for Lash Artists:

  • Client Retention – Well-maintained eyelash extensions mean happy, returning clients.
  • Lash Health – Removing overgrown lash extensions prevents damage and discomfort.
  • Professional Reputation – Clients will trust you more if their lashes always look neat and balanced.

As a beginner, learning how to properly execute an efficient and clean infill will improve your skill set and help you build a loyal client base.

How Often Should Clients Get Lash Infills?

Each client’s natural lash cycle is different, but as a rule of thumb, infills should be done every 2–4 weeks. The goal is to perform an eyelash infill when at least 40% of the eyelash extensions remain intact.

Factors That Affect Lash Retention:

  • Natural Lash Growth Cycle – Some clients shed faster than others.
  • Eyelash Aftercare Routine – Clients who cleanse properly and avoid oil-based products will retain lashes longer.
  • Lifestyle – Frequent sweating, swimming, or rubbing the eyes can shorten lash extensions retention.
  • Lash Extension Glue & Application Technique – Using a strong eyelash glue like I AM Lash Touch Lash Adhesive ensures better retention, but proper isolation and attachment are key.

Step-by-Step Guide to Performing an Lash Infill Appointment

1. Lash Assessment

Before starting, inspect the client’s lashes to determine:

  • How many eyelash extensions are still attache
  • How many eyelash extensions need to be removed due to overgrowth
  • Any gaps that need extra attention

This will help you decide the best approach for filling in the lashes.

2. Removing Outgrown Eyelash Extensions

Lashes that have grown too long or lost direction should be removed using I AM Lash Pro Curved Tweezers or a gentle Gel Remover. Avoid tugging on natural lashes - only remove extensions that are no longer aligned properly.

3. Cleansing & Prepping Lashes

A clean lash line ensures better eyelash extensions retention. Always cleanse the lashes using I AM Lash Cleansing Foam and prime them with Lash Pre-treatment and Primer, if needed to remove any oils or debris before eyelash extensions application.

4. Isolating & Applying New Eyelash Extensions

Using Isolation Tweezers, carefully isolate each natural lash and apply fresh eyelash extensions where needed. Make sure to:

  • Match the length, curl, and thickness of the original set.
  • Place the extension 0.5-1mm away from the lash line for comfort and proper attachment.
  • Use the right amount of lash extension glue - too much eyelash glue can cause stickies, while too little lash glue can result in poor retention.

5. Checking for Balance & Symmetry

Once all necessary lashes are filled in, step back and check for:

  • Even distribution and fullness
  • Any twisted or misaligned extensions
  • Lash direction and symmetry
  • Lash stickies

Make adjustments if needed before finishing the eyelash appointment.

6. Final Brushing & Aftercare Advice

Brush through the lashes using a Lash Brush to separate and fluff them. Provide eyelash extensions aftercare instructions to your client to help them maintain their lash extensions until the next infill.
