There is a common debate amongst lash artists: B vs C curl lashes. Which should you use? And, what is the difference?


We’ve got the quick and dirty for our novice lash lovers that want to learn more about lash extensions or want to settle the debate of B vs C curl lashes.

B vs C Curl: Which One Should You Use?

B Curl

Classically wispy is what comes to mind when we think of the coveted B curl eyelash extension. The base of this lash extension is fairly straight; however, has a slight lift at the end of the lash. Like the J curl, this extension resembles the look of a natural lash. Because of this, the B curl lash is the perfect extension for clients who want an effortlessly natural look! Overall, this extension will add substantial volume and length-but not curl!- without appearing overly dramatic.


Quick: Natural curl. Mimics the look of a naturally uncurled eyelash.

Best For:

Clients who want a subtle enhancement.

Creating a natural “no-makeup” lash look.

Pairing with straight or slightly curved natural lashes.

Pros of B Curls:

Perfect for clients who prefer a low-key style.

Ideal for mature clients or those who wear glasses (no lash bumping!).

Great for blending with natural lashes for a seamless finish.

Cons of B Curls:

Won’t create a dramatic or lifted effect.

May look too subtle for clients with down

C Curl

The C curl eyelash extensionis the lash that keeps giving! This lash extension has a short and straight base with a natural curl at the end of the extension. Even better, this extension complements all eye shapes! From almond to downturned eyes, you can’t go wrong with mixing and matching these natural. It’s no wonder that this eyelash extension is one of the most used extensions on the market.


Quick: Appearance similar to that of an eyelash curled by an eyelash curler.

Lifting and brightening the eyes.

Pairing with natural lashes that already have some curl.

How to Choose Between B Curl and C Curl Extensions

When deciding between B curl vs. C curl for your clients, there are a few factors to consider:

1. Eye Shape
B curls are great for almond-shaped or deep-set eyes, where less lift is needed.
C curls work beautifully on round or hooded eyes to create a more open look.

2. Natural Lash Shape
If the client’s natural lashes are straight, B curls blend seamlessly.
For naturally curled lashes, C curls enhance the lift without overdoing it.

3. Client Preference
Always ask your client how they want their lashes to look. Some prefer a natural vibe, while others want that wow factor!

4. Lifestyle
B curls are ideal for clients with active lifestyles or those who wear glasses.
C curls add a touch of glam but still feel comfortable for everyday wear.
