Lash Extension FAQ
Professional Guide by Sense Lashes
Question 01 What is the difference between C curl and D curl lashes, and how should I choose?
C curl offers a natural arch suitable for daily wear and most eye shapes, while D curl has a stronger curve for dramatic effects ideal for parties or drooping lashes. You can also mix both by using C curl at the inner corner for transition and D curl at the outer corner to create a natural yet layered cat-eye effect.
Question 02 Which curl is suitable for inner double eyelids or swollen eyes?
L curl or LC curl is recommended for inner double eyelids or swollen eyes. L curl has a flat base and sharp lift to prevent lashes from being pressed down by eyelids, while LC curl combines L's support with C's softness to open up the eyes while maintaining a natural look suitable for daily wear.
Question 03 Which curl is least likely to go wrong for first-time lash extensions?
Beginners should start with J curl or B curl. J curl closely matches natural lashes for a no-makeup look with no burden, while B curl adds a slight lift for a bit of movement without being obvious. Both have high adaptability and fault tolerance, making them ideal for first-time experiences or clients preferring a light look.
Question 04 Can I mix different curls in one set, and how to make it look natural?
Yes, mixing curls is a common professional technique for creating dimension. Transitioning from J or B at the inner corner to C in the middle and D or CC at the outer corner creates a natural gradient, while using L or LD for local drooping areas and C elsewhere ensures coordination.
Question 05 Does lash curl affect retention?
Curl type does not directly determine retention, but matching the natural lash growth direction reduces stress and improves retention. True retention depends on glue quality, technician skill, and aftercare.
