Eyelash Extension Fills: Ultimate Guideline From Start to Finish

2025.09.11

Extensión de pestañas fills are a crucial part of maintaining a beautiful, full lash line. They are not just a cosmetic touch-up—they’re essential for keeping the extensions looking fresh and healthy between full sets. Lash fills are a part of routing lash maintenance. For lash artists, understanding the nuances of when and how to perform fills can significantly impact client satisfaction and retention.

When Do You Need Eyelash Extension Fills?

Once your client has a full set of eyelash extensions, they will need to come in periodically for fills. The general recommendation is every two to four weeks, depending on individual lash shedding cycles and lifestyle factors. In general, it’s best to perform a refill service when the client has at least 40% of the lash extensions left from the full set.

Clients who wait longer may require more time during their appointment or even a new set altogether. However, some lash artists find it easier to remove all the remaining lashes and start a new set at the cost of refill.

Lash Extension Fill: Tips and Tricks

When performing an eyelash extension fill, several key steps ensure quality results:

Tidy up the eyelash extensions that are still on the client’s eyes
Remove lashes that are overgrown and ready to fall out due to the natural growth cycle
Remove any weak bonding lashes
Fix any obvious cavities between lashes & lash extensions

This process ensures that only secure, properly aligned lashes remain before applying new extensions.

What Makes Lash Extensions Fall Out?

Several factors contribute to premature lash loss:

Naturally Grown Out Lashes

Does your client know that, with or without lash extensions, most of us shed 70-80 of our natural lashes every two weeks? This natural shedding cycle makes regular fills essential.

Client’s Lash Aftercare Routine

The bond between the client’s natural lashes and the eyelash extension weakens over time due to oil or other impurities. Improper aftercare can accelerate this process. Key culprits include:

  • Excessive makeup use

  • Oily products like removers

  • Sleeping face-down or on one side

  • Aggressive face washing

  • Exposure to heat or water

Using products like lash nourishing Lash Shampoo can help maintain cleanliness and bond strength.

Wrong Application

Application errors by the technician can also lead to early fallout:

The lash extensions are not attached properly.
You are using glue that dries too fast.
You didn’t clean or prime the lashes properly.
The product you are using is expired or your lash room is not in optimal condition.

Proper training and high-quality products like those from ESSI LASH can significantly reduce these issues.

Step by Step: How to Remove & Fill Lash Extensions

Performing a fill correctly begins with proper removal:

  1. Remove overgrown lash extensions by using tweezers or a remover.

  2. Deep clean the lashes using lash shampoo and remove all the oil and skin/makeup debris.

  3. Prime the lashes.

  4. Apply new lashes.

Partial Lash Removal Methods Before a Refill

Lash Removal with Tweezers

Using tweezers to remove lash extensions is generally not recommended as it can be too forceful and can result in bent or damaged natural lashes.

Banana Peel Method

Using two sets of tweezers, grab one natural lash with one tweezer and one extension with the other, then gently separate them vertically into two directions.

Lash Extension Remover

While slower than tweezers, using a lash remover is a much safer and less damaging way to do it. Two effective techniques include:

  • Isolate and hold the neighboring lashes and apply the lash remover. Wait 2-3 minutes and clean off the remover

  • Use a cotton pad or tape to isolate and hold the overgrown lashes.

Client’s Lash Aftercare Routine

Client education is vital for long-lasting results. Remind them that:

This weakening of the bond depends on your client’s lash care habits. If they’re not careful, it can happen much faster.

Encourage clients to avoid oil-based products, sleep on their back if possible, gently cleanse their face daily, and use dedicated cleansers like ESSI LASH Foam Cleanser.

Why Do Some Lashes Stick Out So Much After a Few Weeks?

This common issue stems from applying extensions onto fast-growing natural lashes. The reason behind this is because you lashed on natural lashes that are in their fast-growth phase.

To prevent this: either don’t apply lash extensions on these tiny lashes or apply an extension 1-2mm shorter than the neighboring lash extensions.

How Much Should I Charge for a Lash Refill?

Pricing varies by salon but generally follows this guideline: most salons charge 50% of the full set price for a fill as long as the client comes within 2-3 weeks. Some salons also charge per added extension or based on appointment duration.

Can I Continuously Fill the Lashes Instead of Doing a Full Set?

While tempting for cost-conscious clients, continuous fills aren’t ideal for long-term health. If you continuously fill the set, it is inevitable that some dirt, oil, or debris from the products can remain between the lashes. Additionally, even strong natural lashes need occasional rest.

ESSI LASH recommends removing all extensions after two fills before applying a fresh set.
