When to Get Lash Refills: The Ultimate Guide

Lash extensions are a beauty investment — and like any investment, they require upkeep. One of the most common questions lash clients ask is: When should I get a lash refill?

In this guide, you’ll learn how often to get refills, what signs to look for, and how to maintain your extensions between appointments for maximum retention.

How Often Should You Get Lash Refills?

Most lash artists recommend scheduling a lash refill every 2 to 3 weeks. This timing helps replace extensions that have naturally fallen out and keeps your lash line looking full and even.

Factors that affect refill timing:

• Your natural lash growth cycle

• How well you follow your aftercare routine

• Your lifestyle (e.g., workouts, sleeping position, exposure to water/steam)

Signs You Need a Lash Refill

Not sure if it’s time? Watch for these signs:

• Noticeable gaps in your lash line

• Twisted or grown-out extensions

• Less than 40% of lashes remaining

• Lashes look uneven or less voluminous

• You find yourself using mascara to compensate

If you’re seeing any of these, it’s probably time to book your refill.

What Happens During a Lash Refill Appointment?

A lash refill isn’t just a quick fix—it’s a mini-refresh for your entire lash set.

During a refill, your lash artist will:

• Remove outgrown or loose extensions

• Clean and prep the natural lashes

• Apply new extensions to restore fullness

Refills are quicker and more affordable than a full set — but only if done on time.

Why Timing Matters

Waiting too long between refills may lead to:

• Loss of shape or volume

• Increased shedding

• The need for a full set instead of a refill

• Additional cost and time

To avoid that, most lash techs require at least 40% of your extensions to be intact for a refill appointment.

How to Extend the Time Between Refills

Want to stretch the time between appointments without sacrificing your look?

Tips to help your lashes last:

• Follow a strict aftercare routine

• Avoid oil-based products and waterproof makeup

• Sleep on your back with a silk pillowcase

• Gently brush your lashes daily

• Use lash-safe cleansers and products

Final Thoughts

Knowing when to get lash refills is key to keeping your lashes full, fresh, and flawless. By sticking to a consistent schedule and practicing good lash habits, you can enjoy your extensions without constant upkeep.

Pro Tip: Book your next refill right after your appointment to secure your preferred time.

FAQ: Lash Refill Timing

How many lashes should I have before a refill?

You should have at least 40–50% of your extensions left. If fewer remain, you may need a full set.

What happens if I wait too long for a refill?

You may experience sparse lashes, uneven appearance, or have to book a full set at a higher cost.

Can I go more than 3 weeks without a refill?

It depends on your lash growth and aftercare. Most clients need a refill by week 3 to maintain a full look.

Is it okay to remove grown-out lash extensions at home?

No. Always let your lash technician handle removal to avoid damaging your natural lashes.

What if I lose more lashes on one eye?

This is common — sleeping on one side can cause more friction. A lash artist can balance it during your refill.
