Eyelash Growth Related to Climate or Genetic Issue

Long eyelashes have been a symbol of beauty for many cultures. Long eyelashes are believed to form a contrast between the eye and the eyelid, making your eyes look visibly bigger and thus more attractive. Biologically, eyelashes protect our eyes from dust, debris, and other environmental particles. The lash length is influenced by genetics, but other factors can affect it, too.

Eyelash growth is a natural process that takes place in three stages: the anagen (growth) phase, the catagen (transition) phase, and the telogen (resting) phase. During the growth phase, the hair follicle produces new hair, lasting up to 30 to 45 days in the case of eyelashes.

The catagen phase of the lash hair follicle cycle, during which the eyelash hair follicle shrinks and the hair stops growing. Finally, the resting phase, in which hair follicles remain inactive or several months before the old hair falls out and a new cycle starts.


According to scientists, eyelashes have an optimal length of a third of the eye’s width. This length helps your eyes stay wet and cleaner. This also means if you have big eyes, you may have long lash strands, too. This condition is often referred to as trichomegaly. Eyelash trichomegaly can have several different causes. These causes can include both environmental and inheritance causes (including side effects of certain medications). Sometimes, trichomegaly occurs as part of a congenital disease or syndrome. These conditions are present from the time you are born, either due to genetics or otherwise. Cornelia de Lange syndrome and Oliver Mcfarlane syndrome contribute to the growth of long lashes. If both mother and father have long lashes, you have a high chance of inheriting them.


Ethnicity does not have an impact on your lash length. Asian people and those of Spanish and Eastern European descent tend to have straight lash strands, while others commonly have curlier eyelashes. Not having double eyelid creases causes straight eyelashes. Having a monolid causes those little strands to grow downward and out rather than out and upwards. 

Nutritional deficiency

Severe malnutrition can give rise to chronic hair loss. Hypoproteinemia contributes to hair loss by early onset of telogen (resting phase of eyelash hair follicle cycle). Zinc deficiencies like acrodermatitis enteropathica can contribute to the loss of eyelash hair. Other nutritional deficiencies like iron, biotin, and iron make it possible to lose hair. 

Age, hormones, and Diseases

Aging and menopause are the leading factors that cause inadequate or shorter eyelashes due to specific hormonal imbalances that directly impact the growth cycle of hair follicles. Other conditions may also contribute to the loss of eyelashes. These include drug side effects, various skin diseases, metabolic abnormalities, endocrine disorders, inflammations, psychiatric disorders, traumatic insults, toxins, and systemic disease. 


There are several other ways to improve the length and shape of eyelashes. These include extensions,  tint, lift, and curling. Before deciding on any of these treatments, choose a reliable platform with estheticians specializing in lash extensions. This is important because incorrectly applied extension can contribute to premature loss of lashes, while curling your delicate strands can break them in half.

Therefore, it is recommended to use a lash growth serum that will not only grow long lashes but also strengthen them and help minimize the damaging effects often noticeable with the prolonged use of extensions.

Long lashes caused by certain drugs

Moreover, it is not just genetics that can cause long and luscious eyelashes. Certain drugs can make it possible, too. A drug known as Bimatoprost careprost , which is used to treat glaucoma, can promote lash growth. Bimatoprost stimulates hair follicles, extending their growth phase and increasing lash length. Careprost Bimatoprost is sold as a prostaglandin lash serum that helps to grow lashes longer, darker, and thicker. 

Erlonib, a medication used to treat lung cancer, has also been shown to cause trichomegaly. It also causes stimulation of hair follicles, leading to abnormal lash growth. As mentioned above, trichomegaly can have several different causes; some are genetics, and some do not have an association with genetics.                

The bottom line!

While long eyelashes are the clear winner in beauty and protecting eyes, short or inadequate eyelashes disappoint many. In addition to being considered less attractive, being too short or having inadequate lashes can also be a medical issue. After all, short lashes aren’t sufficient enough to protect the eye from dust and foreign particles. Short eyelashes are a common physical characteristic from various causes, including genetics, hereditary factors, cosmetics usage, illnesses, medications, and aging.

Consult a doctor to understand which option could be best for you to boost eyelash length without or with minimal side effects. You can buy careprost online from your longer, thicker and darker eyelashes.
