How to Apply Bottom Lash Extensions: Tips for Lash Artists

Adding bottom lash extensions to your services can make a huge difference in how your clients' lashes look. They’re perfect for those who want a fuller, more balanced effect but don’t want to deal with mascara smudging. The process may seem a bit tricky at first, but with the right technique, bottom lash extensions are a game-changer. This simple addition can elevate any lash set to a whole new level.

What Are Bottom Lash Extensions?

Bottom lash extensions are applied to the natural lashes on your lower eyelids, just like top lash extensions. However, the technique and materials used for bottom lashes are generally more delicate. Because lower lashes are shorter, thinner, and fewer in number than upper lashes, they need smaller, lighter extensions to look natural and to put no unnecessary tension on fragile lashes.

Types of Looks Bottom Lash Extensions Complement

Bottom lash extensions are a perfect complement to various lash styles. They assist in achieving a symmetrical, balanced look and can help maximize the preferred eye shape.

• Doll Eye: Bottom lash extensions add extra definition, making the eyes appear larger and rounder, similar to a doll's eye shape.
• Kim K Look: The bold, voluminous top lashes paired with soft, subtle bottom lash extensions provide a glamorous yet natural finish, enhancing the full, fluttery look.
• Anime Style: Bottom lashes add an exaggerated, animated effect that’s especially popular in dramatic, artistic lash designs.

Benefits of Bottom Lash Extensions

Bottom lash extensions have a few benefits that can take any lash set to the next level. To begin with, they give the lashes more definition, which frames the eyes and adds depth to the overall appearance. They are also great for clients who do not wish to have mascara smudging or constantly need touch-ups, especially for emotional occasions such as weddings or photo shoots. Bottom lash extensions render mascara obsolete, providing a flawless, all-day appearance.

Who Should Get Bottom Lash Extensions?

Ideal Candidates for Bottom Lash Extensions

Bottom lash extensions are a service that can fit a wonderful number of clients. They are perfect for someone who wishes to enhance their natural beauty or make the shape of their eyes look more defined and symmetrical. Following is a list of ideal candidates who will adore the full, fluttery look bottom lashes provide:

1. Brides – Ideal for brides who do not want to worry about mascara smudging during emotional moments or outdoor weddings.

2. Clients Who Love a Full, Fluttery Lash – Clients who enjoy dramatic lashes will find that bottom extensions enhance their top lashes beautifully.

These customers will appreciate the long-lasting, mascara-free look that is provided by bottom lash extensions, with no daily touch-ups.

When to Skip Bottom Lash Extensions

Bottom lash extensions are not for all clients. Here are some cases when you shouldn't apply them:

• Very Thin or Short Lower Lashes: If the lower lashes are too thin or too short, retention will be bad because the extensions will not have enough natural lashes to hold onto.
• Upward-Pointing Lower Lashes: These lashes can be difficult to apply extensions on and could be painful if not done correctly.
• Sensitive Eyes or Frequent Irritation: Clients with sensitive eyes or those who are more susceptible to irritation should skip bottom lash extensions. Thinner skin and lashes on the lower eye make it more prone to glue and extension irritation

Assessing Natural Bottom Lash Health

Before applying bottom lash extensions, it's crucial to evaluate the condition of your client’s natural bottom lashes. Here’s how to assess them:

• Length: The lower lashes must be long enough to hold an extension. If, for example, your client has extremely short lower lashes that are only a few millimeters long, it may be difficult to apply extensions without them looking too harsh or fake. The best length for extensions is 4-7mm, but the natural lashes should be fairly close to this measurement to get the best results.
• Density: Observe the fullness of the natural lashes. If the client has sparse or patchy bottom lashes, there might not be adequate lash to adhere extensions to. For instance, if very few lashes can be seen or they are fine, extensions might result in poor retention and an unbalanced look. If the lashes are too sparse, it is better to either skip the service or recommend lighter lash mapping.
• Strength: Determine if the natural lashes are strong enough to support the extensions' weight. For instance, if the lashes are thin and weak-looking, they might not be able to sustain even light extensions. If the natural lashes are healthy and thick, they can usually support 0.10mm–0.15mm extensions.

If the lower lashes are healthy, well-placed, and perfect for extensions, they will enhance the overall look beautifully. Otherwise, it is best to avoid this service or suggest something alternative.

How to Select the Right Lash Length, Thickness, and Curl for Bottom Lash Extensions

When applying bottom lash extensions, it's essential to choose the right specifications to ensure a natural look and optimal retention. Here's a detailed breakdown:

Lash Length

For bottom lashes, shorter lengths are advised in order to ensure a natural look and to avoid discomfort.

• Recommended Lengths: 4–7mm
• Placement: Employ shorter lengths (e.g., 4–5mm) on the inner corners and slightly longer lengths (e.g., 6–7mm) on the outer corners to achieve a balanced appearance.

Lash Thickness

Choosing the right thickness makes the extensions light and comfortable for the client.

Recommended Thicknesses:

• 0.10mm: Suitable for clients with sparse or fine natural lashes.
• 0.12mm: Ideal for clients who want a natural appearance with slightly more volume.
• 0.15mm: Gives a fuller look to those clients who have thicker natural lashes.

Lash Curl

The curl type impacts the way the extensions integrate with the natural lashes as well as the desired look.

Recommended Curl Types:

• J Curl: Provides a subtle lift, ideal for clients who want a natural enhancement.
• B Curl: Creates a soft curl, giving a soft definition without being too dramatic.
• C Curl: Gives a more dramatic lift, ideal for clients who want a more open-eyed appearance.

Lash Material

The material of the extensions affects their look and texture.

Recommended Material: Faux mink lashes are ideal for bottom lash extensions as they are extremely light in weight and have a natural finish.

How to Apply Bottom Lash Extensions: A Step-by-Step Guide

Step 1: Clean and Prime the Lashes

• Cleanse the Area: Carefully clean the lower lash line with an oil-free lash cleanser to clear out any makeup, oils, or particles. This is for the best adhesion of the extensions.
• Prime the Lashes: Use a lash primer on the lower lashes to cleanse them of any remaining oils and strengthen the adhesion between the natural lashes and the extensions.
• Protect the Upper Lashes: Use micropore tape to lift and secure the upper lashes, preventing them from interfering during the application process.

Step 2: Isolate Each Lash

• Use Fine-Tipped Tweezers: Gently separate each natural bottom lash so that only one extension is added per natural lash.
• Keep Proper Angle: Keep the tweezers at a suitable angle to prevent any discomfort to the client and to achieve accurate isolation.

Step 3: Apply the Extensions Precisely

• Select Proper Extensions: Select extensions that are 4–7mm long and 0.10–0.15mm thick to ensure a natural look.
• Pick Up Extensions Upside Down: In order to have the curl facing downwards, pick up the extensions from the tray upside down.
• Apply Adhesive: Submerge the base of the extension in a thin-viscosity adhesive and let it become minimally tacky prior to application.
• Place the Extension: Position the extension onto the isolated natural lash, making sure it does follow the natural downward trajectory.

Step 4: Seal and Finalize the Extensions

• Apply a Super Bonder: Apply a super bonder to close the adhesive, minimizing fumes and improving retention.
• Final Check: Make sure all extensions are fastened tightly and that the lash line is even and natural-looking.
• Client Aftercare Instructions: Inform the client to not rub their eyes, use oil-based products, or get the lashes wet for the initial 24 hours.

Common Mistakes to Avoid When Applying Bottom Lash Extensions

Applying bottom lash extensions requires precision and care. Avoiding common mistakes ensures a safe and effective application.

1. Skipping Lash Protection

Always use micropore tape or eye pads to protect the skin and prevent irritation. This prevents the sensitive area beneath the eye from potential adhesive contact and minimizes discomfort risk.

2. Not Isolating Lashes Properly

Separate each bottom lash gently so as not to bunch. Isolate lashes with fine-tipped tweezers so that extensions adhere to single natural lashes and not other extensions.

3. Eyes Open During Application

Have client's eyes closed to avoid exposure to glue fumes. Open eyes can result in irritation or allergic reactions from having the adhesive in close proximity to the eye.

How to Care for Bottom Lash Extensions

In order to preserve the longevity and appearance of bottom lash extensions, customers need to observe some crucial lash extensions aftercare tips, They should also follow the specific advice below:

• Avoid Getting Them Wet in the First 24 Hours: This will allow the adhesive to fully set, creating a strong bond.
• Use Oil-Free Products: Oil removers and cleansers can weaken the adhesive bond. Use oil-free products instead to maintain retention.
• Low-Key Cleaning: Clean the lash area once a day with a mild, lash-friendly cleaner to sweep away debris and prevent accumulation.
• No Rubbing or Pulling: Refrain from touching, rubbing, or pulling on the lashes to prevent early loss.
• Touch-Ups: Schedule refill visits every 2–3 weeks to maintain the fullness and appearance of the extensions.

How Long Do Bottom Lash Extensions Last?

Bottom lash extensions last shorter than upper lash extensions, typically 1 to 2 weeks. This is because the lower lashes are more exposed to facial oils, moisture, and natural shedding, causing the extensions to break down faster.

What Affects the Longevity of Bottom Lash Extensions?

There are several reasons that affect the longevity of bottom lash extensions. Firstly, bottom lashes have a faster shedding cycle than upper lashes, so the extensions naturally fall out sooner as well. The zone under the eyes is more prone to oils and dampness, which can dissolve the adhesive and dislodge the extensions. Also, sleeping on the side or touching your eyes can dislodge the extensions prematurely.

How to Make Bottom Lash Extensions Last Longer

• Gentle Cleansing: Clean the area with an oil-free, lash-safe cleanser so that the adhesive does not break down.
• Avoid Oil-Based Products: Stay away from oil-based makeup and skincare products on the lower lash line for longer-lasting extensions.
• Proper Aftercare: Advise your clients to avoid rubbing their eyes and recommend sleeping on their backs to minimize friction on the lashes. Regular Touch-Ups: Because lower lashes fall out quicker, get clients to return every 2 to 3 weeks for refills to maintain the fresh look.

A little extra care goes a long way in maintaining their natural beauty. Don’t forget to remind your clients about regular touch-ups for the best results!

How Long Do Bottom Lash Extensions Take?

The application of bottom lash extensions typically takes between 15 and 30 minutes, depending on factors like the number of lashes applied and the client's natural lash condition. This process is faster compared to applying a full set of upper lash extensions, making it a great add-on service during regular appointments.
