Lash extensions have become one of the most popular beauty trends in recent years, allowing individuals to achieve longer, fuller, and more voluminous lashes. While top lash extensions are widely known, bottom lash extensions are gaining popularity for those who want to enhance their entire eye area.
In this post, we’ll dive into everything you need to know about top and bottom lash extensions, compare the differences between them, and recommend the best types of lashes for each.
Top lash extensions: How they work
Top lash extensions are applied on the upper lash line using a specialized adhesive. They come in a variety of materials, lengths, colors, and curls to cater to different preferences.
How to use top lash extensions?
When it comes to top lash extensions, there are several techniques to choose from, each offering a unique look tailored to your client’s preferences. Classic lash extensions provide a natural, subtle enhancement by applying a single extension to each natural lash, perfect for those wanting a simple, refined look.
If you’re aiming for a bit more volume and texture, hybrid lashes mix classic and volume techniques for a fuller yet still soft appearance. For clients craving more drama, volume lashes add multiple lightweight extensions to each natural lash, creating a fluffy and bold effect. And if you want to take it up a notch, mega volume lashes offer ultra-dense, full lashes that make a serious statement.
Plus, lash artists can play around with different lash maps like the doll eye or cat eye to customize the style even further, giving each client a look that’s uniquely theirs! Whether you’re going for natural or full-on glam, there’s a lash technique that’s perfect for everyone.
Bottom lash extensions: How they work
Bottom lash extensions are applied individually to each natural lower lash, just like top lash extensions, but with more precision to match the natural look of your bottom lashes. These extensions tend to be shorter, thinner, and have a more subtle curl to ensure a natural appearance.
How to use bottom lash extensions?
For bottom lash extensions, we highly recommend going with the classic 1:1 technique. The classic 1:1 approach is perfect for bottom lashes because it adds just the right amount of length and volume without making things too heavy or overwhelming. Since the lower lashes tend to be finer and shorter, this method helps them blend smoothly with the natural lashes, creating a soft, elegant result.
The great thing about using the classic 1:1 technique is that it prevents clumping or adding too much weight to the delicate bottom lashes, so everything stays comfortable and looking natural. They are also widely used in Anime lash styles or wispy lash sets

Differences between top and bottom lash extensions
1. Length, curl and thickness
When it comes to top lash extensions, you have a lot of flexibility! You can choose any length, curl, and thickness based on your client’s preferences and their natural lash health. Whether your client wants long, dramatic lashes or something more natural, top lash extensions offer a wide variety of options to create a custom look.
However, bottom lashes are typically thinner and more delicate than the top lashes. To keep things looking natural and avoid any damage, it’s important to use shorter, thinner, and lighter extensions. This ensures that the bottom lashes blend well with the rest of the lash set without putting too much strain on the fragile lower lashes.
For bottom lashes, we recommend using lightweight extensions such as Faux Mink lashes in thicknesses of 0.10, 0.12, and 0.15, with lengths ranging from 4-7 mm. As for curls, options like J, B, or C provide a natural curve that enhances the eye without overwhelming the lash line. The goal is to create a harmonious look that complements the top lash extensions while maintaining the integrity of the lower lash line.
2. Retention
When comparing the retention of top and bottom lash extensions, upper lash extensions tend to last longer, usually around 3-4 weeks. While bottom lash extensions tend to fall out faster due to blinking and the natural shedding of lower lashes. Typically, bottom lashes last around 1-2 weeks before needing a refill.
3. Application time
For top lash extensions, the time it takes can vary depending on the technique you choose. For a classic set, lash artists typically spend around 1 hour to apply the extensions. However, if you’re going for a volume or mega volume look, or using a more customized lash map, it can take anywhere from 1.5 to 2 hours to get everything just right.
As for bottom lash extensions, the process is much quicker since there are fewer lashes to work with. Usually, it takes about 15 to 30 minutes to apply bottom lashes, depending on the experience of the lash artist and how many extensions are being added. It’s a pretty fast procedure, which makes it easy for clients to achieve gorgeous bottom lashes without spending too much time in the chair!
4. Application technique
As we mention above, the application process for upper lash extensions offers more versatility in styling, allowing for looks like cat-eye, doll-eye, squirrel-eye, colored lashes, or a natural lash look. Various techniques, including wispy, classic, volume, and hybrid applications, can be used to achieve different effects.
For bottom lash extensions, we highly recommend going with the classic 1:1 technique. The classic 1:1 approach is perfect to prevent clumping or add too much weight to the delicate bottom lashes.
5. Density
The upper lash line can handle a higher density of extensions, allowing for a fuller, more dramatic look. In contrast, bottom lashes require a lighter, less dense application to keep the overall appearance balanced and natural without overpowering the eyes.

FAQs about bottom and top lash extensions

Yes! When applied correctly, bottom lash extensions are completely safe.

Choosing the right length, thickness, and curl is also key to keeping them safe and natural-looking. Always go to a trained professional to avoid any irritation or damage to your natural lashes!
