What Are Classic Lash Extensions?

Classic lash extensions are the foundation of most lash services. They're applied using the 1:1 technique—one extension per natural lash—making them ideal for clients looking to enhance their natural lashes with added length and curl. Classic lashes typically have a round base, which can give them a slightly thicker and more noticeable appearance.

This style is perfect for clients who have naturally thick or full lashes and want a subtle enhancement. The added curl and length help give the eyes more definition without drastically changing the natural look.

 

Benefits of Classic Lash Extensions:

• Added Length and Curl: Perfect for clients with natural volume who want a little extra length and lift.

• Faster Application: Since you only apply one extension per lash, the process can be quicker for experienced artists.

• Affordable: Classic lash extensions are often more budget-friendly for clients who are new to lash services.

• Great for Beginners: Many lash artists start their career by mastering classic lash extensions because of their straightforward technique.

 

What Are Flat Lashes?

Flat lashes, also known as ellipse or cashmere lashes, are a modern upgrade to classic lash extensions. These lashes feature a flat base, which allows for better retention and a lighter feel. While still applied in the classic 1:1 style, their unique shape makes them an ideal choice for clients who want a more dramatic yet comfortable look.

The flat base hugs the natural lash better than the traditional round base, resulting in a stronger bond and longer-lasting extensions. This means less adhesive is needed, which can make the process gentler on the natural lash.

 

Benefits of Flat Lashes:

• Lighter Weight: Perfect for clients with fine or weak lashes, as flat lashes apply less strain on the natural lash.

• Better Retention: The flatter base offers more surface area for adhesive, making the lashes last longer.

• Enhanced Eyeliner Effect: Flat lashes create a fuller, more dramatic look, similar to wearing eyeliner without any makeup.

• Less Adhesive Required: The broader base allows for more even adhesive spread, minimizing the amount of product needed.

When to Use Classic Lash Extensions vs. Flat Lashes

As a lash artist, it’s important to understand when each type of lash extension is appropriate to use.

Addressing Common Client Concerns

Clients often ask how these lash types affect wearability and long-term lash health. Classic lash extensions can sometimes feel heavier, especially on fine lashes. 

For clients with weaker natural lashes, flat lashes offer a safer, lighter alternative with better longevity.

Moreover, flat lashes give off a darker, more striking appearance due to their concave shape, which mimics the look of eyeliner. This makes them a popular choice for clients seeking a bold but effortless appearance.

Application Tips for Lash Artists

The difference in base shape between classic and flat lashes means you might need to adjust your application techniques slightly. 

Here are some tips:

For Classic Lashes: Since these have a round base, focus on precise alignment when attaching the extension to the natural lash. The round base requires a secure bond for optimal retention.

For Flat Lashes: The flatter base makes adhesion easier, so you may find your application process quicker and cleaner over time. Ensure the extension aligns with the natural lash for maximum surface area contact and better retention.

Conclusion: Which Is Better?

As a lash artist, choosing between classic lash extensions and flat lashes comes down to understanding your client's needs and lash health. Flat lashes are often considered superior in terms of comfort, retention, and appearance. Their lightweight nature and ability to create a dramatic, natural look make them a fantastic option, particularly for clients with delicate lashes.

However, classic lash extensions remain a go-to for clients who prefer simplicity and a subtle enhancement. They are affordable, easier to apply, and deliver reliable results for many lash artists.

Ultimately, the best choice depends on your client's natural lash condition and desired look. Keep both options in your portfolio to cater to a wide range of clients and elevate your lash game!
