When it comes to eyelash extensions, most of the attention goes to the upper lashes. But in recent years, a niche service has been making waves: bottom lash extensions. While not as commonly offered as classic or volume sets, lower lash extensions are becoming a conversation topic among lash artists and clients alike. The question is — should you offer them in your salon?
What Are Bottom Lash Extensions?
Bottom lash extensions are lightweight synthetic fibers applied to the client’s lower lashes. Unlike upper extensions, which focus on creating length, curl, and volume, bottom lashes are subtle enhancements designed to add definition to the eyes. The result is a more balanced look that complements a full upper lash line.
Lower lashes can visually enlarge the eyes, make mascara unnecessary, and provide a polished look for clients who want their lashes to look styled from every angle. While not for everyone, this service has a dedicated following among beauty enthusiasts, models, and clients who frequently wear extensions on their upper lashes.
Why Bottom Lash Extensions Are Trending
Several factors explain why bottom lash extensions are becoming a hot topic in 2025:
- Social media influence: Platforms like Instagram and TikTok showcase dramatic before-and-after transformations featuring lower lash sets.
- Full-face aesthetics: More clients are asking for treatments that complete their overall look, rather than focusing on one feature alone.
- Fashion and festival beauty: Bold looks, including colored and accented bottom lashes, are popping up on runways and in editorial shoots.
- Innovation in lash products: Brands are developing thinner fibers and gentler adhesives that make bottom lash applications safer and easier.
Just like other lash trends, bottom lashes are driven by a demand for personalization. Many clients don’t just want fuller upper lashes — they want an eye look tailored to their personality and lifestyle.
Who Is a Good Candidate for Bottom Lash Extensions?
Not every client is the right fit for bottom lash extensions. Here are some situations where this service can work well:
- Clients with strong natural bottom lashes: They need enough lash strength to support the extensions.
- Clients who wear lash extensions on their upper lashes: Lower lashes help balance the look for a more natural finish.
- Special event clients: Weddings, photo shoots, or fashion events are perfect occasions for this enhancement.
- Clients who want to ditch mascara: Lower lashes provide definition without the smudging or flaking of mascara.
On the other hand, clients with very sparse lower lashes, sensitive eyes, or a history of eye irritation may not be good candidates. In these cases, offering alternatives — such as lash tinting — might be more appropriate.
How Bottom Lash Extensions Are Applied
Application is a delicate process that requires advanced skills. The steps usually include:
- Preparation: The lower lashes are cleaned, dried, and separated using eye pads or tape to protect the skin.
- Selection of lashes: Technicians typically use thinner diameters (0.10 mm or less) and shorter lengths (5–8 mm) to ensure comfort.
- Application: Using precise isolation, the lash artist applies 20 – 40 extensions per eye, depending on the client’s natural lash density.
- Finishing touches: Once dried, the lashes are brushed and checked for even spacing and comfort.
Compared to upper lash extensions, the process can be trickier due to the smaller lash surface and the sensitivity of the lower eyelid area.
Benefits of Offering Bottom Lash Extensions
When done correctly, bottom lashes can elevate your lash services in several ways:
- Enhances symmetry: Creates a more balanced and complete lash look.
- Adds definition: Clients get the effect of mascara without the mess.
- Upsells your services: Offering bottom lashes as an add-on can increase appointment value and client satisfaction.
- Differentiates your salon: Not every lash artist offers this, making it a niche specialty that sets you apart.
Risks and Challenges to Consider
Despite the benefits, bottom lash extensions are not without challenges:
- Retention issues: Lower lashes are finer and more prone to shedding, so the extensions may not last as long as upper sets.
- Client comfort: The eyes are more likely to water during application, which can affect adhesive bonding.
- Increased sensitivity: Some clients may feel irritation due to adhesive fumes being closer to the eye surface.
- Time and skill required: The service demands precision and patience, which may increase appointment times.
Because of these challenges, many lash artists recommend bottom lash extensions only to experienced extension wearers or for special occasions.
Aftercare for Bottom Lash Extensions
Proper aftercare is critical to keeping bottom lash extensions looking their best:
- Avoid rubbing the eyes or pulling on the lashes.
- Use an oil-free lash cleanser daily to remove dirt and oils.
- Avoid heavy eye creams or products near the lash line.
- Book touch-ups more frequently, since retention may be shorter than upper lashes.
Clients should be educated about realistic expectations — these lashes may only last one to two weeks compared to the two to three weeks typical of upper lash refills.
Should You Offer Bottom Lash Extensions?
Deciding whether to include bottom lash extensions in your salon menu depends on your skill set, client base, and business goals. If your clients love bold or complete lash looks, adding this service could make sense. However, if most of your clients prioritize low-maintenance beauty, the extra cost and upkeep may not be worth it.
For lash artists, offering bottom lash extensions can expand your expertise and position you as a trend leader in the industry. But before promoting it widely, consider doing trial sets with trusted clients to master the technique and assess demand.
Final Thoughts
Bottom lash extensions are not for everyone, but they are a creative and high-fashion service that continues to gain attention. Whether you decide to add them to your menu or not, staying informed about lash trends ensures your clients see you as an expert who keeps up with the latest in beauty.
