FAQs

What are lash extension curls?

Lash extension curls are different shapes and degrees of curl applied to synthetic lashes to enhance the natural lashes. They range from subtle curls like J and B curls to dramatic curls like D and DD curls, each creating a unique eye-opening effect.

Can you curl lash extensions?

No, you should not curl lash extensions with a traditional eyelash curler because extensions come pre-curled by the manufacturer. Using a mechanical curler can damage or break the extensions. If you want a more pronounced curl, ask your lash technician to apply a curl style that suits your preference during your appointment.

How do I choose the right lash extension curl?

Choosing the right curl depends on your natural lash condition, eye shape, and desired look. For example, J and B curls are for a natural look, C and CC curls for moderate lift, and D or DD curls for dramatic volume. L and LC curls are ideal for downward-pointing lashes or hooded eyes.

How long do lash extension curls last?

Lash extension curls last as long as the extensions themselves, typically through the natural lash growth cycle of 6-8 weeks. Proper aftercare, such as avoiding oil-based products and not rubbing lashes, helps maintain the curl and prolong retention.

What is the difference between lash extension curls and a lash lift?

Lash extension curls refer to the pre-curled synthetic lashes applied to your natural lashes, while a lash lift is a treatment that curls your natural lashes from the base using a chemical solution. Extensions add length and volume, whereas a lash lift enhances the natural lash curl without adding length.
