Both lash fills and full sets are essential parts of maintaining beautiful, long-lasting lash extensions. A full set gets you started, and fills help you keep the look going strong.

Eyelashes, also known as cilia, are a type of hair that grows from the eyelid. Like all hair, eyelashes have a growth cycle that consists of three phases: anagen, catagen, and telogen. The anagen phase is the active growth phase, during which the lash grows rapidly. This phase can last anywhere from 30 to 45 days, depending on the individual.
