Most commonly, Kylie goes for a 'mixed' set, using a blend of both classic and volume lashes. Classic lashes are a one-to-one application of extensions to natural lashes, giving a more understated appearance. Volume lashes, on the other hand, are fan-shaped clusters applied to each lash, providing dramatic fullness.

Polybutylene Terephthalate (PBT) is a high performance engineering polymer. It's more expensive, trickier to colour and manufacture but lashes made from this material are soft, strong and have a gorgeous, natural glossy sheen.

Permanent lash extensions are implants of new lashes along your upper and lower lid. Because you're not receiving an extension on your current lash, they don't fall out with your other lashes. Instead, you receive new follicles that stimulate and encourage new lash growth.

Lash extensions are fibers that are glued onto the natural eyelashes to create a thicker, longer eyelash. However, lash extensions can damage or rip the natural lashes. If natural eyelashes are lost due to lash extensions, they typically grow back in a few months.
