B Curl vs. J Curl: How to Choose the Perfect Eyelash Extension Curl

February 18, 2021 by The Lash Professional. 

Let’s talk about one of the trickiest decisions we lash artists face—choosing the right curl for our clients. Today, we’re diving into the subtle yet significant differences between B curl vs. J curl. These two styles may seem similar, but each one brings a unique vibe to the lash game.


As a lash artist repping The Lash Professional, I’ve seen how mastering these subtle curls can create stunning, personalized looks. Whether your client is all about natural beauty or looking for a soft, polished enhancement, let’s explore how to decide between these two classics.

What is a B Curl?

B curl extensions are the happy middle ground between natural and noticeable. With a slight curve, they add a touch of lift while still looking incredibly natural. Think of them as the “everyday glam” curl that fits most lash goals.


Best For:

-Clients who want a natural enhancement with a bit of polish.

-Blending seamlessly with straight or slightly curved natural lashes.

-Creating a soft, effortless look.


Pros of B Curl Extensions:

-Perfect for clients who want subtle, everyday lashes.

-Adds length and definition without looking overdone.

-Ideal for mature clients or those who prefer a low-key style.


Cons of B Curl Extensions:

Not dramatic enough for clients seeking a bold, lifted effect.

May look too subtle on downward-facing lashes.

What is a J Curl?

J curl extensions are the most natural-looking of all the lash curls. With only a slight lift, they mimic the shape of natural lashes, making them perfect for clients who want a barely-there enhancement.


Best For:

-Clients who want their lashes to look as natural as possible.

-Enhancing naturally curved lashes with a touch of length.

-Professional or minimalist styles.


Pros of J Curl Extensions:

-Creates an ultra-natural look that’s hard to detect.

-Great for blending with natural lashes.

-Perfect for clients who are new to lash extensions and want a subtle start.


Cons of J Curl Extensions:

-Doesn’t add much lift, which can make eyes appear less open.

-Not ideal for clients with straight or downward-facing natural lashes.
