How to Choose the Perfect Lash Curl and Thickness for Your Clients — A Complete TDANCE Lash Artist’s Guide
Choosing the right curl and thickness for lash extensions may seem like a small detail, but it’s one of the most important decisions a lash artist makes. These choices define the overall style, comfort, and durability of the set — and can completely transform how a client looks and feels.
At TDANCE, we know that one size never fits all. That’s why we offer a wide variety of curls, thicknesses, lengths, and specialty lash types — giving lash artists the flexibility to tailor every set to each unique client.
In this blog, we’ll walk you through the fundamentals of lash curl and thickness selection, with real-world examples and expert tips from the TDANCE lash community.
Understanding Lash Curls: From Subtle to Dramatic
Lash curls are what give the extension its personality. Choosing the right curl affects not only the visual impact of the lashes, but also how they interact with the client’s natural lashes and eye shape.
Here’s a quick breakdown of TDANCE’s most popular curls:
- J Curl – Almost straight with a soft bend. Best for natural-looking sets or clients who want a “mascara” effect without the curl. Often used in bottom lash extensions.
- B Curl – Slightly more curved than J curl. Great for clients with naturally straight lashes or those wanting a soft enhancement.
- C Curl – The most versatile and widely used curl. Perfect for creating a lifted, open-eye effect. Works well on most clients and blends easily with natural lashes.
- CC Curl – A step up from C curl, offering a more visible lift and drama while still looking wearable for everyday clients.
- D Curl – Deeply curled for a glamorous, eye-catching finish. Ideal for clients who love bold looks or have downward-pointing lashes.
- L & L+ Curl – Sharp upward lift with a flat base. These are perfect for monolids, hooded eyes, or straight Asian lashes. They create a wide-open effect with maximum retention.

✨ Pro Tip: Don’t be afraid to mix curls across the lash line — for example, using C in the inner corners and D on the outer corners for a natural cat-eye effect.
Choosing the Right Thickness: It’s All About Balance
The thickness (or diameter) of lash extensions plays a big role in both the look and the health of your client’s natural lashes.
TDANCE offers multiple diameter options designed to suit every lash style and skill level:

💡 Always assess your client’s natural lash strength. Applying extensions that are too heavy can lead to premature shedding or lash damage.
Matching Curl & Thickness to Eye Shape and Client Goals
Every client is unique — and that’s what makes lashing so creative! Here’s a simplified reference to help guide your decision:

🎨 Remember to ask clients about their lifestyle and preferences — do they wear makeup daily? Want something bold for events? Or soft for everyday? This will help you recommend the best curl-thickness combo.
