Bottom Eyelash Extensions Do Exist!

One of the most common questions I get from both clients and newer lash artists is: "Can you do extensions on the bottom lashes too?" The answer is absolutely yes—and at Lash Affair, we've been advocates for bottom lash extensions since the beginning. They're the secret weapon behind those full, dramatic doe-eye looks that so many clients bring in as inspiration photos. Here's everything you need to know about offering and applying bottom lash extensions.

Why Bottom Lash Extensions Matter

Top lash extensions on their own can look stunning, but without complementary bottom lashes, the overall look can feel unbalanced—especially with dramatic volume sets. Bottom extensions complete the frame around the eye, creating that wide-eyed, polished finish clients are after. Think of it like this: top lashes without bottoms is like wearing a full face of makeup but skipping mascara on the lower lashes. The look is good, but not complete.

Choosing the Right Lashes for Bottom Extensions

Bottom lash extensions require a completely different approach than top lashes. The extensions should be significantly shorter—typically 5mm to 7mm—and thinner in diameter than what you'd use on top. I recommend using .07mm or .10mm diameter classic lash extensions for bottom applications. Anything thicker will look unnatural and put unnecessary weight on the delicate lower lashes. Stick with J or B curls for a natural look; stronger curls can poke or irritate the under-eye area.

Application Technique

Applying bottom lash extensions requires patience and a steady hand. The client keeps their eyes open during application—which is the opposite of top lash extensions and can feel strange for both artist and client at first. Use a gentle low-fume adhesive since you're working near open eyes. Isolate each lower natural lash carefully with your fine-tip tweezers and apply one extension per natural lash. Work slowly, especially when you're first learning—speed comes with practice. Taping the upper lashes out of the way with medical tape helps maintain a clear working area.

Setting Client Expectations

Bottom lash extensions have a shorter lifespan than top extensions because lower lashes have a faster growth cycle—typically two to three weeks compared to four to six weeks for upper lashes. Make sure clients understand they'll need more frequent touch-ups for their bottom lashes, or they may be disappointed when they shed faster than the top set. Some artists offer bottom lash extensions as an add-on service during regular fill appointments, which keeps the maintenance manageable for clients.

Pricing Your Bottom Lash Service

Bottom lash extensions should be priced as a separate add-on service. While the lash count is lower (typically 10 to 20 per eye), the precision required makes it a skilled service worth charging for. Most artists price bottom extensions at 30 to 50 percent of their full set cost, or offer a flat add-on fee. Position it as a premium enhancement that completes the look—clients who see the difference rarely go back to top-only sets.

Common Challenges and How to Handle Them

The biggest challenge with bottom lashes is client comfort. Working with eyes open, applying near the waterline, and managing the occasional watery eye all require patience. Have tissues ready, work in small sections, and reassure your client throughout the process. Some clients' eyes water more than others, which can affect adhesive cure time—using a nanomister between small sections helps. If a client is extremely sensitive, suggest trying just five to eight extensions per eye first to see how they tolerate it before committing to a full bottom set.

Aftercare for Bottom Lash Extensions

Bottom lash extensions require the same careful aftercare as top extensions, but clients need to be especially gentle when cleansing the under-eye area. Recommend a foaming lash cleanser applied with a soft brush, and remind clients to avoid rubbing their eyes or sleeping face-down. Oil-based makeup removers and heavy under-eye creams should be avoided near the lash line. Proper aftercare dramatically improves retention on both top and bottom sets.

Frequently Asked Questions

Are bottom lash extensions safe?

Yes, when applied correctly by a trained professional using appropriate products. The key safety considerations are using a low-fume adhesive (since the client's eyes are open), choosing lightweight extensions that won't stress the delicate lower lashes, and maintaining proper isolation to prevent lashes from sticking together. If you're new to bottom lash application, practice on a mannequin head before working on clients.

How long do bottom lash extensions last?

Bottom lash extensions typically last two to three weeks before needing a touch-up, compared to three to four weeks for top extensions. Lower lashes have a shorter natural growth cycle, so the extensions shed faster. Many clients schedule bottom lash touch-ups during their regular top lash fill appointments to keep everything looking fresh.

Can every client get bottom lash extensions?

Most clients are good candidates, but some may not be suitable. Clients with very sparse or short natural bottom lashes may not have enough to support extensions. Those with extremely sensitive eyes or conditions like blepharitis should consult with their eye care provider first. Always assess the natural bottom lashes during consultation before promising the service.

Do bottom lash extensions hurt?

No, properly applied bottom lash extensions should be completely painless. If a client feels any pinching or discomfort during application, stop immediately and check your placement. Pain usually means an extension has been applied too close to the skin or multiple natural lashes have been bonded together. Proper isolation and correct adhesive placement prevent any discomfort.
