In the world of beauty, lash infills are one of the most essential services a lash technician provides. As a lash artist, you’ll quickly find that infills are the bread and butter of your eyelash extensions career. They not only maintain the appearance and structure of a client’s lashes but also boost client retention and help build a strong reputation for your lash business.
Whether you’re applying classic lash extensions, hybrid lash extensions, anime lash extensions, or volume eyelash extensions, mastering the infill process is vital. This complete guide covers everything lash technicians need to know—from lash tools and lash maps to adhesive tips and client education. If you’re building a beauty career and wondering how to become a lash technician that clients rave about, start here.
What Are Lash Infills?
Lash infills are maintenance appointments scheduled after the application of a full set of lashes. These appointments replenish lost or grown-out lash extensions caused by the natural lash cycle. Most clients lose 2 to 5 natural lashes per eye daily, which means extensions will begin to thin out after about two weeks.
Infills allow you to:
- Remove twisted or outgrown extensions
- Fill in sparse gaps
- Maintain style consistency (e.g., classic, hybrid, anime, volume)
- Extend the longevity/retention of the lash set
Without infills, a full set of lashes can look uneven, patchy, and lose its initial wow factor. As a lash technician, it’s your job to help clients maintain their lash extensions through proper infill services.
How Often Should Clients Get Lash Infills?
Clients should schedule lash infills every 2–3 weeks. However, this depends on several factors:
- Their natural lash cycle
- Aftercare habits
- Lash extension style
- Use of lash-safe makeup or mascara
It’s also important to assess how much of the original set remains. If less than 40% of the lashes are intact, it’s often better to perform a full set.
Essential Lash Tools for Infills
To perform a flawless infill, every lash artist should be equipped with the following professional lash tools:
- Isolation tweezers and volume tweezers
- High-retention lash glue
- Lash fans (for volume or hybrid sets)
- Eyelash extensions in various curls, lengths, and diameters
- Lash map and client records
- Mascara wand/spoolie brush
- Gel pads or micropore tape
- Oil-free lash cleanser
- Lash adhesive remover
Using high-quality tools ensures better retention, comfort, and client satisfaction.
Step-by-Step: How to Perform a Lash Infill
Whether you’re working with volume eyelash extensions or classic lash extensions, the process for infills remains fairly consistent. Here’s a breakdown of each step:
1. Clean the Lashes
Begin by cleaning your client’s lashes thoroughly using a lash cleanser. Remove oils, makeup, and debris to ensure optimal adhesive bonding.
2. Assess Lash Retention and Health
Check how many extensions remain and examine the health of natural lashes. Use your lash map to track growth patterns and identify sparse areas.
3. Remove Outgrown Extensions
Use tweezers to isolate and gently remove lashes that have grown too far from the lash line. Apply a lash remover if needed, but be cautious to avoid damaging the natural lash.
4. Update Lash Mapping
Adjust your lash map if your client wants to change styles. If they’re sticking to the same look—like classic or anime lash extensions—follow the original lash chart.
5. Isolate and Apply New Extensions
Use tweezers to isolate each healthy natural lash. Dip a new extension into lash glue and apply 0.5–1mm from the eyelid. Be sure to match the curl and length to existing lashes for a seamless finish.
6. Brush and Separate
Use a clean mascara wand to brush through the lashes. Ensure that all lashes are separated and pointing in the correct direction.
7. Educate Your Client
Remind your client about aftercare:
- Avoid oil-based makeup and skincare
- Don’t rub or tug on lashes
- Clean lashes daily
- Avoid waterproof mascara
Client education enhances retention and helps establish you as a knowledgeable beauty professional.
Lash Infill Tips for Different Extension Styles
Classic Lash Extensions
- One extension per natural lash
- Ideal for clients wanting a natural look
- Focus on replacing lashes lost to the growth cycle
Hybrid Lash Extensions
- A mix of classic and volume fans
- Balance fullness and definition
- Ensure you alternate fan and classic lash placements
Volume Eyelash Extensions
- Use premade or handmade fans
- Fill in gaps with appropriate fan sizes to maintain density
Anime Lash Extensions
- Often require longer spikes and specific styling
- Re-map as needed for symmetry
- Pay attention to spacing between bold lash sections
How to Know When a Full Set Is Needed Instead of an Infill
An infill won’t always suffice. Recommend a full set of lashes if:
- Less than 40% of lashes remain
- Multiple lash layers are missing
- There’s excess adhesive buildup
- Your client wants a style change
Doing so ensures the integrity of your lash work and avoids compromising lash health.
Growing Your Beauty Career Through Lash Infills
Consistently executing quality infills is a powerful way to grow your eyelash extensions career. It leads to:
- Repeat clients
- Positive reviews and referrals
- Better client results
- Professional growth as a lash artist
A strong foundation in infills also makes it easier to upsell new lash styles like anime or hybrid extensions.
