What makes eyelashes grow?

Several factors, including genetics, hormones and the immune system, can contribute to eyelash growth.¹ Lifestyle factors like diet and the products you apply to your lashes can affect their health and growth.²

How fast do eyelashes grow naturally?

The lifecycle of an eyelash is approximately four to 11 months and grows between 0.12 and 0.14 millimeters per day. There are three stages to eyelash growth:³

• The growth phase (anagen phase) lasts between four and 10 weeks.

• Degradation phase (catagen phase). The eyelash stops growing and the hair follicle starts to shrink.

• The resting phase (telogen phase) is when the eyelash falls out.

Does crying make your eyelashes longer?

There is no evidence that crying makes eyelashes longer. However, tears may temporarily provide a visual effect of darker or straighter lashes because of the moisture.⁴
