✔ Great for Hooded Eyes – The strong curl keeps lashes visible even with heavy eyelids.

- Those with straight, stubborn lashes that don’t hold a curl well.
- Hooded or monolid eyes needing extra lift and definition.

FAQ
What’s the fundamental difference between C and D curl lashes?
The primary difference lies in their curvature and lifting effect. C Curl features a medium curve resembling the letter “C”, providing a natural-looking lift that enhances eyes subtly. D Curl has a significantly tighter curl, forming almost a 90-degree angle at the base like the letter “D”, which creates a more dramatic, wide-eyed effect. While C Curl offers about 50-60% lift, D Curl delivers 70-80% lift, making it ideal for those wanting bold, attention-grabbing lashes.
Which eye shapes are most suitable for each curl type?
C Curl works beautifully for almond-shaped, round, and slightly hooded eyes, as it provides balanced enhancement without overwhelming natural features. D Curl is particularly flattering for monolid, deep-set, and heavily hooded eyes, where its strong lifting power helps open up the eye area. However, those with protruding eyes should generally avoid D Curl as it may make eyes appear even more prominent.
How do I know which curl will look best on me?
Consider both your natural eye shape and desired look. If you prefer a soft, natural enhancement that subtly defines your eyes, C Curl is ideal. Opt for D Curl if you want noticeable drama and maximum eye-opening effect. Your lash technician can apply sample lashes of each curl during consultation to help you visualize the difference. Those with straight natural lashes often benefit more from D Curl’s stronger hold.
Can these curls be combined in one set?
Absolutely! Many skilled artists create custom looks by blending curls. A popular technique uses C Curl for inner corners (40-50% of the eye) transitioning to D Curl toward the outer corners. This “curl gradient” technique gives natural softness near the nose while adding drama at the outer edges, creating beautiful dimension. Another approach is using C Curl for bottom layers and D Curl for top layers in volume sets.
Which curl is better for first-time lash clients?
For first-timers, C Curl is generally recommended as it provides noticeable enhancement without feeling dramatically different. It allows clients to gradually adjust to extensions. However, if a client has very straight or downturned natural lashes or specifically requests bold lashes, D Curl may be appropriate. A patch test with both curls can help determine comfort level before committing to a full set.
How does each curl affect lash retention?
D Curl typically offers slightly better retention (lasting 3-4 weeks) because its tighter grip adheres more securely to natural lashes, especially beneficial for those with oily eyelids. C Curl may require more frequent touch-ups (every 2-3 weeks) as its gentler curve allows more natural movement. Proper application technique and aftercare significantly impact retention for both curl types.
Conclusion
Choosing between C Curl and D Curl depends on the client’s desired look, eye shape, and lifestyle. C Curl is perfect for subtle enhancement, while D Curl delivers bold, eye-opening drama. Many lash artists mix both curls (e.g., C on inner corners and D on outer corners) for a customized effect.
For lash technicians, stocking both curls ensures versatility in styling. As a manufacturer, we provide high-quality C and D curl lashes in various lengths and thicknesses to meet all professional needs.
