Are 0.18mm classic lash extensions suitable for everyday wear? They can be, but 0.18mm classic lashes are best suited for clients with strong natural lashes. For everyday lash wear on most clients, 0.15mm classic lash extensions are the safer and more comfortable choice. Which curl gives the most dramatic effect with 0.18mm classic lashes? D curl creates the most open-eye, dramatic classic lash look. CC curl is slightly more wearable for everyday lash drama while still delivering bold classic lash definition. Can I use 0.18mm classic lash extensions in a hybrid lash set? Yes — use 0.18mm as the classic lash base for a bold hybrid lash set and add Easy Fanning Lashes 0.07mm fans for texture and volume. What length and curl options are available for 0.18 classic lashes? This tray includes an 8–15mm mix with C, CC, and D curls, so you can create a softer lift, everyday definition, or a more dramatic open-eye effect. Who are 0.18 classic lashes best for? They are best for clients with strong, healthy natural lashes who want a bolder classic lash line than 0.15mm, while staying in a 1:1 application. Is this a single length or mixed tray? This product is an 8–15mm mix tray, giving you multiple lengths in one tray for flexible classic lash mapping.
