When most people think of eyelash extensions, the focus is naturally on the top lash line. But as the "Clean Girl" and "Manga Lash" aesthetics take over Perth and the rest of Australia in 2026, a common question is popping up in DMs and consultation chairs: "Can you get eyelash extensions on bottom lashes?"
The short answer is a resounding yes—but it’s not as simple as flipping your technique upside down. Bottom lash extensions are a specialised service that requires a delicate touch, the right Posh Deluxe supplies, and a solid understanding of eye anatomy.
In this guide, we’re breaking down the "nitty-gritty" of lower lash sets so you can offer this high-end add-on with total confidence.
What Exactly Are Bottom Lash Extensions?
Bottom lash extensions are ultra-lightweight fibres applied to the lower natural lashes. Unlike the top lashes, where we often play with dramatic lengths and volume fans, the goal here is balance and definition.
When you’re working on the lower lid, the extensions are typically:
- Shorter in length: Think 4mm to 7mm.
- Finer in diameter: Usually 0.05mm or even 0.03mm.
- Subtle in curl: Generally J or B curls are used to avoid the lashes poking the client's skin or looking "spidery."
Because lower lashes are naturally finer and have a shorter growth cycle, this is considered an advanced service. It’s the "finishing touch" that transforms a great set into a masterpiece.
Can You Apply Them Safely?
Safety is the "be-all and end-all" here. Because the lower lashes sit so close to the delicate skin of the under-eye, there is zero room for error. You can safely offer this service if:
- The client has healthy natural lowers: If they’re too sparse or fragile, the weight (even a 0.05) might be too much.
- You’ve mastered isolation: A "sticky" on the bottom lash line is significantly more uncomfortable than on the top.
- You use low-fume adhesive: The eyes are often slightly more exposed during bottom lash application, so using a high-quality, professional-grade adhesive is a must to prevent "red eye."
When to Recommend (and When to Walk Away)
Not every client is a candidate for bottom lashes. At Posh Deluxe, we recommend them for:
- The "Full Frame" Look: Clients who have a dark, dramatic top set and want to avoid looking "top-heavy."
- Special Events: Brides or clients heading to a photoshoot who want that "perfectly symmetrical" eye.
- The Mascara-Free Lifestyle: For the Perth active types who want to hit the gym or the beach without lower-lash mascara smudging.
When to say "no": If a client is a chronic eye-rubber, has extremely watery eyes, or has very "upturned" lower lashes that grow toward the eyeball, it’s best to skip the service. Part of being a professional is knowing when a treatment won't serve the client’s comfort.
The Posh Deluxe Kit: What You’ll Need
You can't just use your standard top-lash kit and expect a win. To get that "spectacular" finish, you need specialised tools.
1. Ultra-Fine Posh Deluxe Extensions
Bottom lashes require the softest fibres. Our Posh Deluxe classic eyelash extensions in shorter lengths are perfect for this. They provide that "mascara-look" without the weight. Using a B curl is often the "sweet spot" for Australian eye shapes—it provides just enough lift without looking unnatural.
2. Precision Tweezers
Isolation on the bottom is a whole different ball game. You’re working in a much tighter space. We recommend a high-precision, slim-profile isolation tweezer. This allows you to get deep into the inner corners without the tool blocking your line of sight.
3. Proper Taping Supplies
To access the bottom lashes, you’ll need to "tape up" the top lashes. Using a low-tack, sensitive tape is essential to ensure the client is comfortable and their top extensions aren't damaged during the process.
Technical Tips for a Flawless Finish
- Isolation is King: Because bottom lashes sit closer together and can grow in various directions, you must work methodically. Isolate one lash, apply, and let it dry completely before moving to its neighbour to avoid "stickies."
- Less is More: You don't need to lash every single bottom hair. Often, a 50-70% coverage is enough to create a beautiful, airy frame.
- The Adhesive Ratio: Use the "bead-less" technique. You want just enough adhesive to create a bond, but not so much that it creates a visible "bump" on such a fine hair.
Managing Client Expectations: The Retention Reality
Here is the "fair dinkum" truth: bottom lashes do not last as long as top lashes.
- Growth Cycle: Lower lashes shed faster.
- Friction: We touch our lower lids more often than our tops.
- Moisture: Tears and eye creams settle on the lower lash line first.
Typically, bottom lashes look "fresh" for about 1 to 2 weeks. We always recommend telling your clients this upfront so they aren't disappointed. It’s often best marketed as a "special occasion" add-on or a "mini-refresh" for their standard infill.
Bottom lash extensions can add polish and balance to a lash set — but they’re not a one-size-fits-all service. Success depends on technique, product choice, and realistic expectations.
For lash artists, understanding when and how to apply bottom lash extensions is just as important as knowing when to say no.
