Let’s demystify the myths right away: trimming eyelashes hardly promotes their regrowth. The complex biology of eyelashes does not conform to this popular belief. Eyelashes, like other body hair, follow a precise growth cycle that is independent of our will. The impact of trimming eyelashes can be detrimental, potentially leading to hesitant regrowth or even permanent alteration. In short, far from stimulating their regrowth, cutting eyelashes can instead condemn them to stagnant growth. Thus, let’s reveal the truth: for healthy eyelashes, spare them from scissors.
Demystifying the Myths: Eyelash Cutting
It is common to see many myths circulating about eyelashes and their length. Women, in particular, are often the target of these false ideas spread by word of mouth or the internet. What if we took a moment to shed light on this issue?

Generally speaking, people think that the longer their eyelashes are, the prettier they are. But is this really a reality? The myth that having long eyelashes is naturally synonymous with beauty needs to be demystified. The notion of attractive appearance varies from person to person and primarily depends on personal taste.
Another common myth is that false eyelashes would damage our real eyelashes. In reality, this can happen, but only if you do not use your false eyelashes correctly or if you overuse them daily without giving your real eyelashes a well-deserved break.

About two months after regular application of false eyelashes, be sure to renew them healthily, as each eyelash needs a complete cycle (which includes birth, growth, and shedding) to grow properly.
A Scientific Overview: The Biology of Eyelash Growth
The biology of eyelashes, those tiny hairs that line our eyelids, is a fascinating research subject for scientists. Thus, understanding their growth piques the interest of many researchers due to the potential implications in various fields such as regenerative medicine or the development of new cosmetic strategies.
To begin deciphering this mystery, you need to understand the anatomy of an eyelash. An eyelash is not just a hair; it has a complex structure that includes the shaft (the visible part), the bulb (hidden under the skin and containing the producing stem cells), and the hair follicle. The last two elements are essential for eyelash growth.
The factors influencing eyelash growth are numerous. One of them is genetic: some individuals are born with genes that favor faster or slower growth. However, other factors can also play a significant role, such as diet—adequate nutrition can promote better hair health—hormones—especially the menstrual phase in women—but also age and even certain personal behaviors like frequently rubbing the eyes.
Recent scientific studies on this issue indicate that a protein called “sonic hedgehog” (shh) plays a crucial role in the eyelash growth process.
Eyelash Cutting: Impact and Consequences
For a long time, eyelashes have been considered a detraction from our eyes. It should be noted that the length of eyelashes has a direct impact on their primary function: protecting the eye from dust and other volatile particles present in our environment.
The ideal length of eyelashes generally ranges from 8 to 12mm. According to various scientific studies, this measurement corresponds to one-third of the width of the eye. This ratio would optimize their protective role while minimizing potential negative effects such as dry eyes.
When the eyelashes are too short, they may not fulfill their protective mission properly. The main risk is that a larger amount of dust and other foreign bodies can enter the eye, which can cause irritations, redness, or infections such as conjunctivitis and blepharitis.
Conversely, when the eyelashes are excessively long, they tend to create a barrier that is difficult for the tear film (a thin layer of liquid that covers the surface of the eye) to cross. By blinking less easily—an action that allows the tear film to spread properly—we promote dry eyes along with its associated discomforts: the sensation of having a grain of sand in the eye, itching, blurred vision…
The Revealed Truth: Stimulating or Stagnating Eyelash Regrowth
It is often accepted that eyelashes play a fundamental role in our appearance. They frame our eyes, the mirrors of the soul, and their density can greatly influence how others perceive us. That is why so many individuals seek to promote their regrowth or, conversely, to stop it. So what are the latest discoveries on this thorny subject?
Stimulating eyelash regrowth is a concern that drives many people who have experienced significant loss or whose natural eyelashes are sparse. Methods can range from pharmaceutical treatments to home remedies, as well as using specific cosmetic products like strengthening mascara.
Medical treatments prescribed by a doctor should be used with caution and only when necessary, as they can have undesirable side effects such as itchy eyes or even a change in iris color.
For those hesitant about this drastic solution but eager to improve the appearance of their eyelashes, there is a wide range of gentler solutions. Some may turn to strengthening mascara, which promises not only to visually lengthen your eyelashes but also to stimulate growth thanks to its specific formulation.
For those preferring to avoid any potentially irritating chemical products for the eyes, be aware that there are several natural remedies that can help stimulate eyelash regrowth.
