Applying a full set of lashes takes about two hours, and can be maintained year-round with touch-ups recommended every three to four weeks. A half set of lashes are an economical alternative to achieve a similarly dramatic effect, applied as filler to thicken natural lashes, or applied outward from the eye for a specialized look.
Everyone has different lashes, and depending on the condition of your own natural lashes, lash experts can only go a certain length or thickness. (This is to ensure that your own lashes remain healthy.) For example, if your natural lashes are on the shorter, thinner side, you won't be able to get a crazy, dramatic Kim Kardashian look
, because it won't last. It's better to start out with a half set (50 to 60 percent of your top lashes) if you aren't sure or it's your first time. It's easier to add more than to remove lashes!
