Does Latisse Grow New Lashes?

No, Latisse does not grow new lashes in places that none existed before, but what it does do is to make the existing lashes grow longer, thicker and darker. This effectively makes it appear that new lashes have grown, but in fact it requires the follicle to already be present but just "dormant" and the Latisse increases and emphasizes the active phase of your lashes.

Latisse works not by growing new eyelashes but by prolonging the growth phase of your existing lashes. All body hair goes through an active growth phase and a dormant phase. By increasing the growth phase the lashes will get longer, thicker and darker.
You probably have a very short active phase and that is why your lashes are sparse. Try Latisse but patient. It takes about 14 weeks to work.

Latisse can appear to make new eyelashes grow but these were most likely in a dormant state. There are approximately 100 to 150 eyelashes on each upper eyelid. The growth of eyelashes is cyclical, going through 3 stages: a growth phase, a transition phase, and a resting phase. At any given time, numerous hair follicles can be found in each of the different stages. The growth phase of an average eyelash hair is approximately 1 to 2 months. Latisse has been shown to increase the amount of time each eyelash hair remains in the growing phase. The application of Latisse has also been scientifically proven to increase the thickness of eyelash hair as well as the darkness of each hair. This is most likely due to an increased production of pigment within each hair follicle. Typically, within 4 months of application, Latisse can increase the length, thickness, and darkness of eyelashes and improve all the traits that are associated with greater prominence and overall attractiveness of the eyelashes.

Ten years ago my wife lost all of her eyelashes due to allergies, none of which regrew. After using Latisse for approximately one year, she has now regrown the majority of her eyelashes.
